Music theorists J. Molino and J.-J. Nattiez believe music has a »unity« and a »universality«. They are founded upon man's biology and his »neuro-cognitive faculties«. On the basis of this assumption they affirm that music has meaning if a human »interpretant« is around to confer meaning on it and deny that music can be meaningful in any other way. To assess the feasibility and creditworthiness of such a theory, this paper adopts an essentially eco-critical perspective. The case is made that founding musical symbolism exclusively on an »anthropological ontology« is problematic and disserves the interests of anthropos, the intended beneficiary. Instead of that, it supposes that it would be better to follow the advice of eco-musicologist R. Murray Schafer and use music to give nature a voice and a language and use the intelligence it communicates as a resource for restoring an entente cordiale with our more-than-human surroundings.
