On the piano:
A glance at the scope and wealth of piano literature makes us realize: this instrument works wonders. But the piano must be an instrument, not a fetish. It serves a purpose. Without the music, it’s a piece of furniture with black and white teeth. A violin is, and stays, a violin. The piano is an object of transformation. It permits, if the pianist so desires, the suggestion of the singing voice, the timbres of other instruments, of the orchestra. It might even conjure up the rainbow or the spheres. This propensity for metamorphosis, this alchemy, is our supreme treasure.
