I am attracted only to music which I consider to be better than it can be performed.

I practice in my head.

Practice in tranquility.

Children are given Mozart because of the small quantity of the notes; grown-ups avoid Mozart because of the great quality of the notes.

I know two kinds of audiences only--one coughing, and one not coughing.

It is not music's function to express rational necessities.

The sonatas of Mozart are unique; they are too easy for children, and too difficult for artists.
