A trans-human source for music? =============================== Brian D. Josephson Cavendish Laboratory, Madingley Road, Cambridge CB3 0HE, U.K. Abstract. Following a discussion of what symbolisms are and the factors that give rise to their development, it is argued that the complex phenomenon of music can best be understood as a category of symbolism. Human culture and evolution by natural selection do not give suitable conditions for a symbolism of the subtlety of music to arise, and it is proposed therefore that some agency of a trans-human nature, some of whose concerns we are able to share, is the original source of the phenomenon. These considerations lead among other things to the proposal that biological signals in general may carry more subtle information than is commonly assumed. 1. Introduction Previous papers [1 - 4] have criticised certain conventional views of music, such as the idea that music is intrinsic to a musical culture and therefore has no intrinsic meaning of its own, and argued instead that music constitutes a general symbol system, analogous in many ways to DNA. The previous work relied heavily on the hypothesis of there being close analogies between DNA and music (such as their both being informational systems of high specificity), but in view of the existence of significant differences in detail between the characteristics of the two kinds of symbol system, especially in that music (like natural language) is processed by a mind that in some sense understands it, whereas DNA expresses its potential by a more passive process, a slightly different mode of attack is appropriate. In the current work the emphasis is put on music as a symbolism, rather than as before on it being a system closely analogous to DNA. 2. The nature and origins of symbolisms The essence of a symbolism, as we shall envisage it in the following, is that it involves agents making use of symbolic expressions, to define processes of greater or lesser complexity, which in turn generate significant outcomes (significance being defined by the agents, in accord with some prescription appropriate in the context of their mode of existence). In formal terms, a symbol system can be regarded as being defined by its associated collection of permitted symbolic expressions and the expressive processes that generate responses to these symbolic expressions. The expressive processes give the symbolism its expressive power, whilst the ability to make use of this expressive power requires the existence also of generative processes which generate symbolic expressions appropriate to the circumstances. In terms of the above description, the evolution of a symbol system can be viewed as the gradual incorporation of more and more powerful expressive processes into the system, in essence through the linking of symbols and concepts, a symbol being the means of providing controlled access to a useful concept, a concept in turn being an aspect of a useful process. An idea that is effective in one situation can, through the mechanism of representing it by a symbol or symbols, be tried out in other circumstances simply by calling up from memory the relevant symbol or symbols. Through the process of trial and error, the concept becomes shaped to have maximal utility. The refinement of a symbol system is seen to be the natural outcome of a succession of acts of creative change on the part of the agents that make use of it, in conjunction with a process of the collection of the most successful new variants. A symbol system may in certain instances be the possession of a single agent (as exemplified by the situation of a person who has invented a new idea with its own terminology, who has not yet shared the idea with other persons), but in the general case aspects of the symbol system become the properties of a cultural group, as a result of members of the group being able to share uses of the symbolic expressions involved and to exchange symbols with one another. 3. The case for music being a symbolism A process such as has been described accounts, in its essentials, for the evolution of natural language. The current proposal is that similar processes gave rise to the phenomenon of music. For such an idea to begin to be worthy of consideration, it would be necessary for it to be able in principle to account for features of music that would be hard to understand according to any other point of view. The most definitive support for the idea that good music signifies something (originally proposed by Suzanne Langer [5]) comes from the area of subjective experience, starting with the fact that listeners to music appear to be able to experience a clear distinction between a type of music that seems to consist simply of recognisable patterns, and music of aesthetic value that appears to be in some way 'significant'. With the 'significant' kind of music there is the feeling that the surface form of the notes fits the context, as is not the case with music that consists merely of recognisable patterns. There is also the feeling that the music involves 'themes' that are 'developed' as a piece of music progresses. Again, there is the experience that both composers and performers have that what they are doing is attempting the accurate expression of an idea in the medium of music. These perceptions parallel corresponding experiences with language, which are often described in almost identical terminology. In the case of language, these features are reflections of the fact that language is a symbolism, and not only a symbolism but also a symbolism that its users know to be a symbolism in the sense that they have some awareness of what that symbolism signifies. While in the above I have referred only to subjective experiences paralleling those of language, analysis of the structure of music indicates the existence of objective parallels also, discussion of which topic lies outside the scope of this paper. At the very least, we can conclude (i) that there is a phenomenon of 'seeming significant' in music; (ii) this phenomenon is tied to very individual structures (individual compositions), implying that appreciable interference with the details of a composition is liable to modify quite strongly the impression of significance; and (iii) seeming significant is not the same as appearing recognisable or familiar. It would seem that significance or aesthetic appeal cannot readily be tied down to rules, and neither would it appear explicable on the basis of the kinds of generalisations that neural nets can make. Both rule-governed structures, and structures formed on the basis of generalisation capacities of neural nets, appear to pertain far more to the question of 'what kinds of sound sound like music' than they do to aesthetic matters. Correspondingly in the case of language, rules and generalisation procedures appear to relate to grammatical categorisations rather than to semantic ones. Assuming that any objections to such a proposal can be overcome, the most reasonable way of accounting for all the parallels between music and natural language would appear to hypothesise simply that music is a symbolism in the sense defined at the beginning of this paper, that is that it has as its basis agents making use of symbolic expressions to define processes of greater or lesser complexity, which in turn generate significant outcomes, with the whole self-organising system having a system of values that leads step by step to the evolution of the symbolism in the direction of increasing expressive power, particularly in regard to the possibility of using it to define ideas that accord with the value systems of the agents concerned. Such processes can, as exemplified by the phenomenon of language, lead to the development of similar complexity to music, as well as to the associated development of a sense of significance or otherwise in relation to symbolic expressions. 4. Trans-human agencies as the sources of musical symbolism While the above hypothesis fits the phenomenon of music in many ways, various questions arise. In particular, who or what were the agents concerned, and in what context did this hypothesised evolution of musical symbolism take place? What were the value judgements that required the processes concerned with the existence of the symbolism to become more and more complex in order to express what was needed in order to conform to the requirements of that value system? To phrase this last question more explicitly, the theory being proposed is that musical symbolism, like natural language, became more and more sophisticated because more and more sophistication had well-defined uses. The question is, what might these uses be? One kind of use would be cultural uses such as use in ceremonies or in song. I shall ignore this possibility as the subtle problems arise largely in connection with more exclusively abstract manifestations of music such as classical music in a purely instrumental context. The claim I shall make here is that because such music may involve radically new 'inventions' there are no grounds for claiming that the meanings involved are ones that have been learnt in the usual way. This leads one to the radical proposal that musical symbolism is in some sense a pre-existing system, which human beings discover rather than invent. The possibility of explanations for apparent meaningfulness on genetic grounds should also be mentioned; however, such explanations suffer from the objection that it is difficult to imagine selection pressures that would lead to the degree of uniformity that does exist regarding aesthetic preferences among those that have given sufficient attention to the kinds of music concerned to be able to appreciate them fully. If human beings discover music rather than invent it, then questions arise such as where does the music come from, and how do we acquire it? To the first question I shall simply give the answer 'from some source or other. This source must simply be some entity satisfying the conditions under which we have presumed complicated symbol systems will develop (i.e. agents making use of symbolic expressions, etc. etc.). And in answer to the question of how do we acquire it, we can simply say: by the same means as those by which human beings acquire language from each other, or to take a more asymmetrical case, pets from human beings (this process also involving shared meaning, shared utterances, and processes for acquiring some comprehension of symbol systems). We are familiar with the way chemicals in the brain have specific effects on thought, and so it should be not be too difficult to envisage the possibility of a similar symbiosis between the mysterious source of music and our own minds enabling us to acquire some kind of understanding of the symbolism and the uses that the source makes of music. The above picture requires for its completion attention to the question of what the concerns may be of the agencies or agency involved with music, these being the concerns that would have driven its evolution. While music in general has, as already noted, no specific denotations in the world, it does, subjectively, appear to relate to general life themes. One might speculate therefore that it originated as a means of symbolising life processes in general, perhaps with the goal of indicating archetypal problems and their resolutions. 5. Conclusions The above has indicated an unorthodox, and yet apparently consistent concept of what music is. In essence, the familiar concept of the existence of symbolisms is hypothesised to be applicable in an unusual, not at all clearly specified domain, and to show its presence only indirectly via the phenomenon of music. Thus a visible regularity is being accounted for in terms of an invisible one, the justification being that the very general mechanism of symbolic evolution leads to phenomena of exactly the kind that are observed. The situation is frustrating in that we can see very few of the details. However, this is a situation that is commonplace in science. The question is what tools may exist to probe the situation in more detail. One avenue of research may be through the study of music, which may provide information about the symbol system and some aspects of its semantics. This would require the development of some kind of understanding of the 'thought processes' implicit in music, and may involve a more perceptive analysis of archetypal aspects of life, that is those aspects which are largely independent of the details of a given organism, than there is in the theories that we have today. Another avenue might involve analyses of possible subtleties of symbolisms in the biological realm generally. Signals in biology are normally assumed to encode information on the basis of only simple features such as amplitude and frequency, but such an assumption may be incorrect. Our difficulties with conceptualising what music is may be a pointer to the existence of a more general limitation of this kind in our understanding of the biological realm.
