Mathemusic is the functional blend (via the loopstring) of mathematics and music (defined as 'an incorporation of keys and timing') whose resultant is a y-proof. This tends more towards being a supermathematical exercise grounded in the principles of music theory. However, it is practically expressing (with libretti) statistics in the framework of music (even sans sonically). Cryptologically, it is the algorithmic direction of variation*. When we speak of mathemusic, we are generally doing so in the context of The Origamic Symphony (and not to exclude Egglepple).Solutions have melodic texture.
