Grammars have been developed which describe many types of music at many different levels. These range from the forms used in jazz, classical and popular music (e.g. blues, sonata, chorus/verse, etc) to stylistic, melodic, rhythmic and harmonic grammars of numerous musical styles.

It is hoped that a number of techniques will be developed, which use many of these different grammars. These techniques can then be put to use for representing in sound the highly-structured systems which are most valuable in communication.
