This article focuses on that portion of zoomusicoligical studies called processes, i.e. behavioural patterns belonging to the realm of the para-musical, including the whole cultural dimension of making music, its rituals, social rules and so on. A particular attention will be given to the processes displaying the establishment of a relation between animals and space (i.e., music as a ritual and social occasion; music and bodily movement; number of performers; the cultural dimension of music;and the management of soundscape, primarily the musical imitation of it). The analysis is transpecific, in that it compares the appearance and the developments of the mentioned traits across different species (the so-called musical universals), notably including the human one.
Key words: Universalia, social space, social interaction
To a large, sometimes cosmological, extent, the problem of musical universals often inhabited the speculations of several philosophers of the past (see Kircher’s Musurgia universalis). In strictly scientific and systematic terms, however, and thus unfortunately in its uniquely human dimension, the question arose again in the 1970s, mainly within the field of ethnomusicology. The urge to investigate the universal characteristics of music went hand in hand with an interest in “other”, non-western musics. Wondering about the universality of music implies wondering about music itself:
It seems to us that there are [many] reasons why ethnomusicology is concerned with the question of the universals of music: first of all, because this discipline … contains an essential comparative dimension; this being the case, ethnomusicologists do not seem yet to have encountered any civilisations without music and are thus led to pose the question: ‘What is music as a universal phenomenon?’, which, in itself, could constitute a first universal feature of music (Nattiez 1977: 92-93).
Universals constitute a theoretical problem that has not found yet a single solution. Various scholars discussed the possible existence of archetypical musical structures, and even whether such a question made sense or not. Among other things, this means that most of the theoretical material that I illustrate from now on is under constant revision or discussion. Yet, I feel it crucial to draw a fair picture of this heterogeneous theoretical landscape: in itself, heterogeneity should not be considered a limit.
First of all, the search for universals in music poses a crucial philosophical question: What is required of a musical element in order to define it as universal? In principle, one can distinguish between two main possibilities:
1. An uncontradictable coherence of given musical traits across all communities ;
2. A continuity at the pragmatic level, i.e., in the way those musical traits work, or in the principles that motivate their appearance within certain (not necessarily all) communities .
Kwabena Nketia (1984: 15) tries to incorporate both hypotheses within the so-called absolute universals (“unrestricted, unconditional universals”) and universal consequents (“the tuning, tonal and metric systems, for example, developed in music through time and cross-culturally are myriad, but that does not mean that the musical working-out of the consequences of such properties will also be myriad in number. Consequential relationships of a universal nature imply common tendencies in both the response to and development of musical materials, not a commonality in the choice of the material themselves”). Ellen Koskoff (1984: 80) has also drawn a possible list of categories concerned with “absolute hard-edged” universals, and “near-universals” (see Table 1)
Universals A (absolute hard-edged)
Universals B (near-universals, easier to find)
- communicated and heard by human ears;
- aspect of form (a. dynamic contour, or b. pitch contour, or c. repetition);
- purposeful (i.e., organised-modulated) presentation;
- stress and release;
- beginning and end
- communication of human feelings;
- projection through physical human effort;
- rhythmic elements;
Table 1 ¯ Koskoff’s classification of musical universals (1984)
Further, Nketia observes that an artistic world-view of music is of qualitative, rather than quantitative type. The approach is rather empirical than general, and it proceeds from the general to the particular. Diversity is certainly inevitable in music, but “it is accommodated in creative and conceptual terms through 1) the postulate of an archetypical source; 2) the concept of music as a world-wide art of which individual cultures are particular expressions; 3) the notion of complementarity and alternative modes of expression; and 4) the universality of aesthetic experience” (Nketia 1984: 6).
There seem to be good reasons to back this position. We shall not call universal only those musical traits displayed by every single musical culture, otherwise the search for universality in music becomes quite a hopeless task. As Mâche reminds,
It is all too easy to show that music is not a ‘universal language’, since the learning of its diverse dialects is always laborious: it involves passing from excessive ethnocentricity to an accepted and perpetuated anarchy. No one has ever imagined … that all musics are alike. It is not essential for data to match up in every detail, without exception, for them to be qualified as universal. It is enough that they should appear in independent contexts, and that their functioning presents analogies too precise to be put down to chance. (Mâche 1992: 42).
Perhaps this is the right way to proceed. We cannot be 100% sure, but it is very likely that Homo sapiens and, for instance, Megaptera novaeangliae constitute “independent musical contexts” . At the same time, it is not in principle problematic that a musical trait shared by humans and humpback whales is not also shared by, say, nightingales.
In classifying universals, zoomusicology adopts the same basic tripartition proposed by ethnomusicologists:
1. Structures. The musical traits in themselves. Analysis of this level implies a large use of sound material, such as recordings and spectrograms, and aims to define the organisation of sounds in the species observed; e.g., range of sounds covered, recurrent intervals, timbres, and so on. Mâche (1992) proposes exactly this typology of research.
2. Processes. Acts and behavioural patterns related to the structures, in the fields of emission and reception. It is the realm of the para-musical, and it includes the whole cultural dimension of making music, with its rituals, social rules and so on. This level constitutes the best-known part of zoomusicological research, with many of its aspects having already been investigated by ethology. The same kind of analysis can be found in Sebeok's Play of Musement (1981), in the chapter entitled “Musical Signs”.
3. Experience. The level that scholars like Stefani, Delalande, and Tagg have proposed in their discussions about musical universals. Since musical experiences may be considered a general experience that takes place between a subject (human or other animal) and an object (musical event), they advanced the idea that a universal feature in each experience is the restatement of particular conducts and competences. With similar presuppositions, this view may be used for zoomusicological purposes. If the first level was that of the objective, and the second of the cultural, this one is surely the level of subjectivity, the investigation of music as an experience lived by an individual (although it is clear that many of these experiences follow general rules).
This essay will focus on the musical processes, and particularly those that have to do with the management of space, in different respects: indeed, the contexts of zoomusicology. Studying musical processes firstly implies that the subject of investigation is not only the sound object itself, for the latter becomes music only as it comes into relation with an animal. Processes constitute this relation, which is the ethological, behavioural aspect of musical activity. Hence, processes concern the use and function of music, its social character, the way it becomes an “event”, a cultural occasion, the way it is performed, the tools it is performed with, the role played by performers and listeners, the relation between such subjects, and so forth. Quite evidently, in many of these occasions, space plays a crucial role. Where does music happen? How important are body, posture, movement? Are there specific musical positions or spaces?
At least the following musical processes concern these matters:
1) the social character of music, i.e., music as a cultural, ritual and social occasion;
2) the crucial relation between music and bodily movement, particularly dance;
3) the musical phenomenon as related to the number of performers, from soloists to duets to groups. In addition to purely structural issues (unisons, polyphony, etc.), the topic carries interesting ethological implications, since its manifestations are strictly related to the function of each musical event;
4) the cultural dimension of music, i.e., what establishes conventions common to a whole community or species, in opposition to individual nuances, which result from different personalities, interests and sensibilities;
5) imitation, what is probably more a non-human than human musical issue, although it will soon become clear how basic this practice is for all musical activity, human or not.
Music and social life are very closely related. Before codifying music as a system of sounds and their organisation, humans and other animals must have codified their music as a system of social rules, from very basic ones, like phatic coordination. That is to say, they establish, through music, certain roles and relations within the members of a community.
According to John Blacking, the emerging of such rules is not totally exclusive of each society, i.e., some universal patterns underlie the setting of those rules:
Evidence of music-making in many different social and cultural contexts convinces me that patterns of music, and people’s uses of them and responses to them, are not entirely arbitrary, that music’s existence as a social fact is more than a result of purely contractual agreements in different societies, and that not only can human beings share feelings but this capacity is fundamental to human evolution (Blacking 1977: 17).
Three main forms of music-social life relation can be distinguished:
1. Music as a support of social facts. Very often, music is chosen as a mere decoration or enhancement of social events. As Gourlay puts it, music is “inseparable from the occasion and purpose for which it is produced” (Gourlay 1984: 35). A large number of social occasions is supported by the use of music; from formal and informal ceremonies to commercial or ideological advertising. The best example, within the animal kingdom, is the celebratory usage of the howling that wolves perform after a successful hunt. In that case, music, as a manifestation of joy, “celebrates” and “enhances” a social occasion, i.e., the pack, safe and warm, gathering after the hunt.
2. Music as a causative factor for social facts. Not only is music the “result” of a social occasion. Sometimes ¯ quite often, in fact ¯ is also the cause of it . Music can be used to establish certain social relations or social roles, thus playing an active role within a community, and interlocking with the more functional role illustrated in the previous point. Examples are many, but a good summary is provided by Frank Harrison (1977: 35), who classifies a typology of the uses and functions of music, emphasising five main categories: reservation, communication heightening, invocation of the supernatural, multiple participation, message sending. Among non-human animals, the obvious instance is mating-related songs, which are a distinctive sign for healthy and skilled males and ¯ through the females’ choice ¯ establish a new social relation between two specimens. Evidently, the same principle applies to group singing, when performed in order to improve communication or enhance group-feeling;
3. Music as exteroceptively related with social facts. Music, in itself, can be a sort of metaphor of social facts, i.e., it may portrait ¯ through structural elements ¯ given social occasions or behaviours. As Lomax puts it, “[…] the models of coordination and cooperation in singing, mirror and support the key patterns of everyday co-action, tradition by tradition, so that, in this way, art and social life are closely linked” (Lomax 1977: 119). In this case, the relation between music and social facts is exteroceptive, i.e., musical structures reflect ¯ mainly through certain topoi ¯ the outer, non-musical world. The production of musical sense occurs also through models and processes achieved from social practices (see Stefani 1998: 17). In imitative practices among birds, for instance, the use of diverse musical sources as part of an individual composition, apart from displaying performers’ skills, mirrors the variety and the events of the surrounding environment. Still among birds, antiphonal and mostly “alternating” duets are a metaphor of the relation established between two mates.
As Bruno Nettl says, “nowhere do we find dancing completely without musical accompaniment” (1977: 5). Along with few other traits, dancing is a really universal phenomenon, whose manifestations can be detected everywhere, in humans and in other animals.
Before any specific consideration of dance it is worth sketching a brief outline of the general use of body in musical activities, and that involves posture, movements aimed to “keep the rhythm”, and so forth. Humpback whales, for instance perform within 40-50 metres of the surface, with both flippers outstretched, and the whole body inclined forward at a 45-degree angle (see Payne 1982: 472). In wolves, the typical “head up” howling position is very well known. And so on. According to some scholars, these musical positions are related to the global meaning that each species attributes to its own singing (e.g., courting, competition with other males). In other words, the musical positions could be a ritualised visual aspect, comparable to a peacock wheel. In this case, cultural-aesthetic interpretations, at least in the ethological sense, are possible.
According to Payne (1996: 154), humpback whales adopt their position in order to allow blood to flow faster to their brain, helping them to recall their songs, which are notoriously long and complex. Thus, it shall be interesting to verify whether certain positions belong to a more complex cultural dimension or a specifically musical one. We know that among many species, singing occurs not only in the mating period. We also know that every now and then, not always, the male’s exhibition is followed by a “romantic encounter” with a female. In addition, the time between singing performance and mating can be so long that one might view the two activities as not necessarily being in a causal relation. If this is true, then the musical position is not necessarily part of the courting strategy ¯ not only, at least. Thus, why not think about specifically musical positions? Human beings, even when only amateur musicians, know that certain postures help them to exploit their vocal resources, and know even better that certain postures make them “look” like real singers (eyes closed, hand on heart, the gestures of rock stars, etc.). If whales are smart enough to help their blood flow to their brain, then why should they not be a little exhibitionists as well?
Let us now focus on dance in the strict sense of the term. According to the many kinaesthetic manifestations of various civilisations, dancing often appears as related to spiritual and/or supernatural issues. As Kurath reminds,
The prime function of dance is transfiguration, identification of the ego with other creatures of the visible and invisible world. Dancers effect transformation by mime of revered animals, of other human beings, of supernatural [entities]. They reach for the spirit world in healing trance or euphoria. They accomplish their aims by means of the universal tool, the human body, moving according to basic physical principles, in space and time. Thus they manipulate the same tool for all techniques, for traditional, regional folkdances and for ubiquitous modern art dances (Kurath 1977: 43).
It is a widely-held opinion that such issues are a strongly species-specific characteristic of the human species, and ¯ despite remarks by Darwin (1871 and 1872) and others ¯ that can hardly be denied. Yet, vague forms of somehow spiritually-connoted aesthetic performances are detectable in other animals, as well. Perhaps not by chance, a convincing example comes from chimpanzees, the closest relatives of humans. Jane Goodall, during her very long and well-known experience with great apes in their habitat, provides an extensive description of what she calls a “rain dance” (Goodall 1971: 54). Of course, as Sebeok (1981: 219) remarks, the meaning of this behavioural pattern is not at all clear. However, what seems to be certain is that chimps dislike rain, thus their dance is possibly not a way ¯ as it is with humans ¯ to invoke water. Is it then to make it stop? We do not know: the “rain dance” as a display of disappointment is probably the simplest option. But one cannot exclude a certain rough degree of spirituality (i.e., the claim that the very act of rain-dancing has some kind of influence on the weather conditions). In both cases, there should be no doubt that we are talking about an aesthetic behavioural pattern.
Another universal in dance is the circle figure. Kurath notices that
The geometric ground plans of group progressions are variations on basic principles, the use of curves or straight lines. Circles are universal, be they closed or open, may the dancers face a central object or the direction of progression. Open circles are really lines that curve into arcs and can develop into meanders or spirals under the guidance of a leader. The direction of circling is important (Kurath 1977: 47)
A good instance of this universal kinaesthetic feature can be found in chimpanzees, who display a peculiar performance that Curt Sachs described as a “genuine round dance”:
In mock fighting two of them drag each other about on the ground until they come near a post. Their frolicking and romping quiets down as they begin to circle about, using the post as a pivot. One after another the rest of the animals appear, join the circle, and finally the whole group, one behind another, is marching in orderly fashion around the post. Now their movements change quickly. They are no longer walking but trotting. Stamping with one foot and putting the other down lightly, they beat out what approaches a distinct rhythm, with each of them tending to keep step with the rest. When two posts or boxes stand close to each other, they like to use these as a centre, and in this case the ring dance around both takes the form of an ellipse. In these dances the chimpanzee likes to bedeck his body with all sorts of things, especially strings, vines, and rags that dangle and swing in the air as he moves about. (Sachs 1937: 10)
Apart from the idea of the circle, this report recalls another aspect that is universal, culturally-related, and erroneously considered exclusively human: body adornment. This feature is displayed not only by apes, but by many bird species, too.
One of the main elements in dance, as in all other forms of art that involve groups rather than individuals, is organisation, in the sense of coordination and cooperation between members of a homogeneous group (see Kurath 1977: 48). Consider this description of dancing performance of a group of cranes, as reported by Anya Royce:
There were some hundreds of them, and their dance was in the manner of a quadrille, but in the matter of rhythm and grace excelling any quadrille that ever was. In groups of a score or more they advanced and retreated, lifting high their long legs and standing on their toes, now and then bowing gracefully to one another, now and then one pair encircling with prancing daintiness a group whose heads moved upwards and downwards and sideways in time to the stepping of the pair. At times they formed into one great prancing mass, with their long necks thrust upward; and the wide swaying of their backs was like unto the swaying of the sea. Then, suddenly, as in response to an imperative command, they would sway apart, some of them to rise in low, encircling flight, and some to stand as in little gossiping groups; and presently they would form in pairs or sets of pairs, and the prancing and bowing, and advancing and retreating would begin all over again. (Royce 1977: 3-4)
The presence of spectators, standing before or around the performers, is characteristic not only of dance, but of music and theatre, too. Spectatorship is a very culturally-connoted aspect in artistic performance, and mostly a display of aesthetic pleasure and amusement.
[A] group of some twenty mountain chickens of a brilliant orange-yellow colour, gathered together in a kind of dance characteristic of these beautiful birds. In the centre one of the cocks executed the dance-like movements, as he hopped about the open place with wings extended and tail outspread. On the branches of the bushes round about, the others sat and expressed their admiration of the dancer with the strangest sounds. As soon as one cock was exhausted, he joined the spectators, uttering a peculiar cry, and another took his place. (Sebeok 1981: 218)
Most interestingly, this example puts into evidence a few points:
1. The above-mentioned idea of performers-spectators: a culturally-crucial feature of the performing arts;
2. The performer in the middle/spectators around set-up: a sheer universal, found in many popular traditions, both in dance and music;
3. The idea of the “event”, the show: the birds actually gather in that place in order to perform; whether or not the dance is for mating purposes, the point is that the twenty cocks and chickens group together in order for each one to exhibit;
4. The idea of applause: as each bird would perform, the others “expressed their admiration of the dancer with the strangest sounds” (Sebeok 1981: 218).
From these observations, the phatic dimension of dance emerges quite prominently. A most interesting case comes from the geese of the species Anser anser, and it is called “ceremony of triumph” (Mainardi 1992: 122-123). In its simplest form, the ceremony occurs as a couple of mates, with or without offspring, meet an unknown male of the same species, who may or may not be invading their territory, but is estimated to represent a threat for the female. The male of the couple then furiously attacks the intruder, arching his neck over him. Usually no fights occur, for the intruder hardly has aggressive purposes. Yet even in the case of challenge, for the same reasons, he does not keep up the fight for long, and soon leaves. The aggressor soon turns towards his mate, then both an apparently euphoric dance, by quickly moving their heads and necks up and down, and uttering their typical nasal sounds.
Insects, too, display an incredibly wide range of dancing performances, most of which are closely related to mating. Nymphalid butterflies are among the most creative dancers.
First, [the male] flutters his wings in front of the female. Then he slightly raises his wings to show the beautiful white black-rimmed spots. He opens and closes his wings rhythmically, his antennae quivering. This lasts from several seconds to one minute. Then (and this is the most gallant posture) the nymphalid male raises his fore wings, opens them wide, and bows deeply. Next, still bowing, he folds his wings back, tenderly pressing the antennae of the female between them. This is a butterfly kiss! And it is not only a posture: on the male’s wings, exactly where he is pressing the female’s antennae, are scent glands ¯ a sign of his masculine maturity. He opens his wings, turns around and a fast dance: he circles around the female with the air of a very successful suitor (Akimushkin 1988: 106-107).
Spiders, too, seem to be very well trained dancers. Igor Akimushkin is tempted to compare some of their performances with classical ballet:
The dance of the small spider Attulus (it is only 3.5 millimetres long) is reminiscent of classical ballet. Propped up by his three pairs of legs (spiders are endowed with long legs indeed) he extends his two front legs to the sky and, sweeping them gracefully, skips sideways to the right. Then he freezes for a second, skips to the left, swaying his 'arms' coquettishly (Akimushkin 1988: 107-108).
These latter performances, which reflect the ordinary movements of the everyday life of these insects, should be related to another universal of dancing: very often, the movements of daily tasks or activities are ‘aestheticised’, then converted into some dance form (see Kurath 1977: 44).
Still among insects, there is an interesting example in which dancing is not only the ideal aesthetic accompaniment to mating-related singing, but also a useful strategy for continuing courtship, in the place of singing. This is the case of green grasshoppers (see Hart 1996: 48-49). Instead of attracting females, a male grasshopper who performs a mating song runs the risk of signalling his presence to a bat, one of his main predators. The typical thrilling staccato, composed of a wide range of frequencies, is an easily locatable signal. Male grasshoppers face the problem in two ways: first, they perform much higher or lower kinds of trills (thus reducing the range of frequencies); second, as soon as they locate a female, they stop singing and complete the mating ritual with a silent dance.
Another, curious, example comes from cichlid fishes:
The mating ceremonies of cichlids, such as Tilapia and Haplochromis, begin by staking out a plot at the bottom. There the male lies flat, beats his tail against the water and spins on the spot to dig a small depression in the sand. Then he sets off in search of a female. As soon as he finds her, the male performs his dance. A Tilapia male slowly swims sideways in front of the female, bending his head at 30° to 60° angle. If the female stops, he waits for her. And then again, in the same strange posture with his head down, he swims sideways towards his hollow leading his mate (Akimushkin 1988: 113-114).
This performance ¯ and, in fact, all the others ¯ stresses on the importance of the dancer’s contact with space. She “moves in certain directions, cuts lines in the air with his body and arms, and with these lines he creates decorative designs and evoke emotions” (Kurath 1977: 47).
What about the previously-mentioned humpback whales? Do such enormous animals actually dance? The word Megaptera derives from ancient Greek, and stands for “big wings”. The humpback whale’s big wings are of course its pectoral flippers, quite bigger than those of any other species of whale, and vaguely recalling bird wings. In 1979, Roger Payne, Sylvia Earle and Al Giddings (see Earle, 1979) first, and Jacques Cousteau eventually (Cousteau and Paccalet 1987: 237), discovered a particular use of the “big wings” when singing. “Al [Giddings] located the singer some fifty or sixty feet down. As it sang, the whale lifted its great flippers forward, then back, in rhythm with phrases of the song” (Earle 1979: 5).
Zoomusicologically speaking, such a behavioural pattern can be interpreted in two ways (either separately or at the same time). On the one hand, there is a merely musical motivation. Humpback whales often deal with rhythmical elements within or in opposition to the strictly melodic parts of their songs (see Payne 1996: 155-156). Thus, the lifting of flippers may be a) a percussive element; b) an attempt to rhythmically frame the song; or c) an attempt to produce further sounds (like splashes) to include as part of the song. On the other hand, this pattern can be interpreted as a mere game, i.e., quite simply, an attempt to make the whole thing more amusing and rich.
The at once subjective and social character of music is well demonstrated by the presence of individual and/or group performances. Animal species, to different extents, perform in both ways. Statistically, solo performances are the more numerous, which also applies to humans; group performances of music occur less often than all the diverse solo performances (from conservatory practicing to singing in the shower). On the other hand, sharing aesthetic experiences with various numbers of one's fellows is a typical characteristic of music and musicality, possibly more than of other art forms, such as painting or sculpturing.
In analysing group performances, a distinction is to be made between duets and groups (i.e., from trios on). A separate treatment for duets is necessary since the characteristics of this type of group musical organisation are quite idiosyncratic and autonomous as compared with the other ones. In birds, certainly the class best known for singing in pairs, several types of duets can be distinguished:
1. Antiphonal, i.e., when singers alternate during the performance. Antiphons may be performed on the same pitch or, more interestingly, at different pitch levels. In such a case, “one of the partners, instead of completing the common phrase, repeats it by transposing it. Among these examples, which inevitably recall human musics, we can cite the duet of African wood-owls Ciccabi woodfordi […], in which the pair holds a peaceful dialogue by repeating the same melodic-rhythmic ritornello, but exactly an octave apart. The African scops-owl Otus senegalensis does the same, but at an interval which is slightly more than a tone [away]” (Mâche 1992: 145). Further, an antiphon does not necessarily consist in the repetition of the same melodic part, but rather in each performer making its own sounds.
2. Unison. Sometimes the singers are perfectly coordinated and perform identical melodies so that it is very difficult to discern that the song is actually a duet and not a solo. This type of duets have gone unnoticed (and considered solo performances) exactly because of their perfect unisonic coordination. As Mâche underlines, “this is particularly the case with several duets in which the notes alternate and complement one another very rapidly [so as] to create a very precise figure. Whether or not they serve to eliminate adulterous suitors from the couple, the sound result is exactly that of the medieval hocket. Percussive duets have also been spotted among storks and some American woodpeckers” (Mâche 1992: 147).
3. Countersinging, finally, occurs when the singers perform at the same time, but with different rhythmic and/or melodic parts.
These distinctions do not imply the priority of one practice over another:
The notes of the duet constitute polyphonic singing, such that the pitch, timing, and phrasing can, to a large extent, be controlled very exactly, but can also be varied by the singers. Either sex can and the other finish, either bird can sing the whole pattern alone if the partner is absent, and, when the partner returns, the two birds can either duplicate in perfect time or resume antiphonal singing. (Sebeok 1981: 224)
In terms of function, one shall distinguish among five types of duets. In all of them, the spatial dimension (especially interpersonal distance) plays a crucial role:
1. Duels. These occur between two different species or between two members of the same species or community. They consist in a musical challenge, in which the most enduring or inventive performer wins, by reducing the opponent to silence . Duels should not be confused with territorial duets, which fulfil a different, more biological function. The plausible explanation of duels is pure amusement  and, probably, training for serious singing (i.e., territorial or mating songs). In fact, both functions should be considered as one: within the whole animal kingdom, thus including humans, having fun is also a way for children and adults to learn useful activities.
2. Territorial duets occur at the moment of territorial division, and basically consist of countersinging or antiphonal singing . The communicative function is thus connative.
3. Mating duets take place during the process of courting and can involve either male and female, or two males competing for the same female.
4. Phatic duets have the explicit function of enhancing the feeling of union between a couple ¯ a John and Yoko kind of thing, if you like.
5. Referential duets occur especially in tropical areas, where dense vegetation prevents animals from seeing each other. In such a case, singing signals or synchronises each one’s position, as in the following case of the platyrrhine monkey Callicebus moloch: “When two or more individuals are within twenty or thirty feet of one another, their songs tend to be very closely synchronised, note by note; synchronisation usually breaks down as the distance between individuals increases. This sort of timing probably has one important advantage, to enable singing individuals to judge, with very great precision, their relative positions vis-à-vis one another” (Sebeok 1981: 227).
Even among amphibians, interesting forms of countersinging may occur. Mâche illustrates an interspecific duet between the Mexican smilisca Hyla Baudini and the burrowing tree frog Pternohyla fodiens. Their countersinging is organised like “a short piece of music in which, after their successive entries, the two voices with their bassoon-like timbre become superimposed with a quasi-scholastic rigour” (Mâche 1992: 145).
Occasionally, among tree frogs, a third singer joins in to form an apparently well coordinated trio. The technique is that of alternating the parts, not necessarily in a strict antiphonal fashion, i.e., not the identical repetition of melodic parts. From a human perspective, the result is hardly intelligible as music .
The latter example opens the door to group performances. Insects, amphibians, canidae and cetaceans are probably the animals most devoted to group singing, at least quantitatively speaking: humpback whales can sing as soloists, duets, trios, “or even choruses of dozens of interweaving voices” (Earle 1979: 19). Birds, as mentioned, are more specialised in duets, but may often perform in larger groups. Marsh warblers are a good example, since they often gather in order to perform together:
We know of duets, trios, quarters and even quintets between males of neighbouring territories. This activity, called ‘social singing’, evokes the human practices of chamber music. It only develops in sunny and still weather, for about five to ten minutes, perhaps ten times shorter than ordinary territorial song. As soon as it is the time for one of the participants to go to relieve his female guarding the nest, and he has returned, all the participants are silent. Some travel daily more than 200 metres from their position to participate in this musical get-together. Others stay away; but many return to the venue of the ‘concert’, generally a neutral zone on the boundaries of several territories, to resume their part as soon as they have been replaced by the female on the nest. The daily concert is gradually abandoned, even if it is fine, when the number of participants becomes insufficient: absenteeism is rife in birds too, and compromises this activity for which zoologists have found no justification other than an aesthetic one. (Mâche 1992: 147)
From duets to ensembles, animals manage their group performances more or less as do humans: countersinging, unison, antiphonal singing ¯ between a duet and also between a soloist and a choir ¯ and even group performances “enriched by solo virtuosisms” (Cousteau and Paccalet 1987: 237).
The presence of individual musical traits in certain non-human animals is not limited only to species that possess a wide collection of sounds and songs:
Individuality is as common in birds with small repertoires as in those with large ones. It occurs, for example, in chirping sparrows that have only one song per individual … and in mistle thrushes and blackbirds, with large individual repertoires [---]. In view of the increasing attention being given to the use of song in classification of the taxonomically difficult tyrannid flycatchers, it is worth remark[ing] that each individual pewee sings his own kind of song every morning; his individual traits persist throughout the season. The individual traits concern every characteristic of the singing. Songs of individual ovenbirds differ in pitch, speed, and details of phrasing [---]. Oregon juncos show great individuality in the structure of the syllables from which the song is made up [---]. Two individuals rarely share identical songs. (Hamilton and Marler 1966: 447)
The balance between individual traits and common features is not necessarily weighted in favour of the latter. In certain species, the diversity of singing patterns within a population is so great that only a few elementary properties of the singing pattern are shared by its members. In the brown towhee, whose main part of the song is a trill of repeated syllables, scholars have described an extraordinary range of syllable types within one population (see Hamilton and Marler 1966: 447). Within a basic framework of patterns that resemble each other in terms of structure and duration, a high degree of intra-population variability is displayed.
The cultural aspects detectable in animal singing are also interesting. It is widely known that birdsong is almost totally a learnt skill. Experiments have demonstrated that, if a bird is raised outside contact with its own family or even species, it will learn the repertoire of its adoptive parents; and further, the new songs will be transmitted from generation to generation. Specimens that become deaf soon after birth develop very poor and incomplete songs (thus proving that singing is also/only partly innate). Finally, the existence of widespread practices such as imitation and vocal mimicry proves how crucial the learning element is among animals.
What is significant for the topic discussed in the present essay is the presence of dialects. Members of a given species from one community tend to resemble one another (usually quite closely) in certain traits of their singing; and those from a community located much further away tend to have a progressively different pattern of average singing traits. As noticed by Thorpe,
sometimes such dialects often seem to serve no particular function, being no more than an accidental outcome of the way in which the song matures. Perhaps … they help to make the song signal more effective by reducing local variability. But in certain cases they must surely help in the early stages of genetic divergence. (Thorpe 1972: 160)
Dialects also seem to be fundamental in terms of individual recognition:
… within the local dialect the individual birds can develop their own peculiarities of song so that this can now serve the additional function of individual distinctiveness. An interesting case of this is shown by songs of the bou-bou shrike Lanarius aethiopicus major (Fig. 5). Here, the members of a pair learn to perform duets with one another and, while adopting certain phrases and rhythms which are characteristic of the locality, work out between themselves the duets which are sufficiently individualistic to enable the bird to distinguish and keep contact with its mate by singing duets with it - or, to be more exact, singing antiphonally with it - in the dense vegetation in which they usually live. (Thorpe 1972: 160-161)
Examples of dialects occur among practically all mammals, but the paradigmatic case of cultural transmission of songs in humpback whales certainly allows to make general observations about the whole issue. The extreme complexity and constant variability of whale singing is well known. Humpback whales’ songs are far from monotonous, and each specimen provides them with several, progressive and individual changes. As soon as modifications occur, the innovations of a song are learnt by all males in the same mating area, so that, at some point, everyone is performing more or less the same version. Singers constantly change their songs to keep in step with the group. As males change area, a not rare event, songs and repertoires are exchanged in several zones, and specimens from the same ocean end up singing quite similar tunes (see Payne 1996: 161). The process of variation and geographical exchange in singing, thus, follows the same rules of the folk songs of oral traditions. Each community has its own repertoire, but this latter is flexible and mixable with others, up to not only including new songs, but also to providing more or less evident modifications of the old ones.
For the record: the geographical characterisation of musical dialects is so evident that it is nowadays more useful for population surveys than are traditional methods. In practice, instead of collecting data through the sighting of specimens, many scholars have to base their information on each specimen according to the type of song it performs (see Payne 1982: 464).
Sound imitation normally implies re-elaboration, abstraction, arrangement, ritualisation, organisation, plus playing and having fun with sounds. All of these activities are fundamental aspects in music-making. Music in itself is a form of imitation, when one considers the use of musical models, conventions and archetypes. Musicians take inspiration from the soundscape that surrounds them, and very often their musical attempts are conscious reproductions of it. (Messiaen’s use of birdsong in his compositions is a most revealing instance).
Birds are no doubt the class mostly devoted to imitation.
[There are] species which mimic widely: the mocking bird (Mimus polyglottos) in the United States, the starling (Sturnus vulgaris) in Europe, and the racquet-tailed drongo (Dicrurus paradiseus) in India are good examples. These birds are something of a puzzle since it is not at all clear what biological advantage is achieved by imitating other species. The Indian mynah Gracula religiosa, however … shares with the parrots the peculiarity that, while supreme imitators in captivity, they have never been heard to imitate any other species in the wild. [---] It appears that these mynahs do, in fact, imitate, but only other mynahs: since mynah calls are of such a wide range of patterns and of such acoustic complexity, this imitation is undetectable by man’s ear without long training and close study of neighbouring individuals. When, however, these birds are hand-reared, they seem to imprint very easily and thus they imitate all sorts of noises in their own environment, particularly the noises most closely associated with human beings. Hence their fame as mimics. (Thorpe 1972: 161-162)
The notion of soundscape is here crucial. The case of the Superb Lyrebird is emblematic. During the mating season, the male of this beautiful bird embellishes his songs with all sorts of decorations, taken both from the extraspecies or inanimate soundscape ¯ such as claxons, dogs’ barking, even electric saws - and from other birds (such as cockatoos and kookaburras, which in turn produce quite varied and complex songs). Sounds are reproduced, re-arranged, or otherwise combined in an original fashion. Such a huge collection of sounds is exhibited to the female as if they were war medals. To say it with Aristotle, the females chooses the male provided with the most “unexpected but believable” repertoire .
Another interesting case is the marsh warbler, who can imitate about forty species, sometimes very faithfully, and sometimes through complex processes of re-arrangement, which lead the songs to very distant points from the original model. What the warbler actually does is assemble a very complex musical “Frankenstein” of the sounds that surround it:
It is not in doubt that practices like that … consisting of integrating into the song alarms and other cries of different species, and of reciprocally constructing alarms, i.e., purely functional signals, by integrating fragments of foreign songs, suppose a kind of faculty of typically musical abstraction. Instead of reacting instinctively to a stimulus, the bird pleases itself: it plays with this international S.O.S. that an alarm is (always understood as such by other species present), by reducing it to simple sound content, proper to its being reused as a kind of musical material. The relative neutralisation that this musical material has to undergo seems to prove, on the bird’s part, both the capacity to classify it in a formal category and a musical imagination [capable of] finding for it another function within the song in which it is re-deployed. (Mâche 1992: 153-154)
A curious case of imitation occurs between the rock thrush Monticola saxatilis and the black wheatear Oenanthe leucura. In this case, the two species imitate each other’s songs as a display of neighbourliness, something like what happens among humans, as when one country hosting a diplomat from another country performs the visitor’s national anthem.
The main goal of this article was that of illustrating, hopefully in an efficient manner, the variety of practices, interactions and roles that underlie the activity of music-making in non-human animals. Most of these activities, perhaps all, display a common articulation with the human musical processes, at least when it comes to rules and principles (but, as we have seen, the similarities go far beyond this general level), giving us a strong clue that the confrontation occurs in the field of homologies, and not simply analogies. Depending on the critical inclination, one might accuse these comparisons of being either too anthropomorphic (if the analysis is perceived as claiming that “animals make music just like humans”), or too reductionist (if the perceived claim is “human music is nothing else than what animals do”). As a matter of fact, both remarks would be inaccurate, as the main point here is, humbly but firmly, that music, as a whole, is a phenomenon with strong biological bases and developments (and that, among other things, makes it worthwhile to seek for musical universals at a zoological level). The (undeniable) fact that most of musical practices find then a specific articulation that belong to cultural domains (human or non-human) is far from being a neglection of such roots, but simply (yet) another confirmation of the Peircean synechistic assumption that nature and culture are not subject to any dualism, but simply represent two points of the same axis.
