Music and Apollinian

Nietzsche's 'Apollinian' is the principle of both Form and Illusion, perhaps reflecting more its derivation from Schopenhauer's concept of Representation, than from classical sources.  However, there is no clear systematic connection between Form and Illusion, e. g. a drawn geometrical figure and a sculpture both possess form, but are not so obviously illusory.  Likewise, Form is what distinguishes Music from random noise, Dithyramb from incoherent shouting, and Dancing from spasmodic lurching.  Furthermore, research of Synaesthesia includes well-documented cases of the 'seeing' of Music.  So, Nietzsche's exclusion of Apollinian influence from Music is equivocal, if not erroneous.
