We need not destroy the past. It is gone.

Discord occasions a momentary distress to the ear, which remains unsatisfied, and even uneasy, until it hears something better. I am convinced...that provided the ear be at length made amends, there are few dissonances too strong for it. Disharmony, to paraphrase Bergson's statement about disorder, is simply a harmony to which many are unaccustomed.

A finished work is exactly that, requires resurrection.

Composing for the prepared piano is not a criticism of the instrument. I'm only being practical.
