The function of music

"Art, and, above all, music, has a fundamental function, which is to catalyze the sublimation that it can bring about through all means of expression. It must aim through fixations which are landmarks, to draw [one] towards a total exaltation in which the individual mingles, losing his consciousness in a truth immediate, rare, enormous, and perfect. If a work of art succeeds in this undertaking even for a single moment, it attains its goal."

Iannis Xenakis

Futurism and Cubism are comparable in importance tot the invention of perspective, for which they substituted a new concept op space. All subsequent movements were latent in them or brought about by them.. ..the two movements cannot be regarded as in opposition to each other, even though they started from opposite points; I maintain (an idea approved by Apollinaire and later by Matisse) that they are two extremes of the same sign, tending to coincide at certain points which only the poetic instinct of the painter can discover: poetry being the content and raison d’être of art.
