Music induces nightingales to sing, pug dogs to yelp.
Play always as if in the presence of a master.
You should neither play bad compositions, nor, unless compelled, listen to them.
Only when the form grows clear to you, will the spirit become so too.
When you play, never mind who listens to you.
My heart pounds sickeningly and I turn pale... I often feel as if I were dead... I seem to be losing my mind.
