As something has involuntarily crept into my head through my eyes,I love to indulge it, even though it may be all wrong.

Having nothing to do, I am correcting the Paris edition of Bach; not only the engraver's mistakes, but also the mistakes hallowed by those who are supposed to understand Bach (I have no pretensions to understand better, but I do think that sometimes I can guess).

A long time ago I decided that my universe will be the soul and heart of man.

If I were still stupider than I am, I should think myself at the apex of my career; yet I know how much I still lack, to reach perfection; I see it the more clearly now that I live only among first-rank artists and know what each one of them lacks.

The three most celebrated doctors on the island have been to see me. One sniffed at what I spat, the second tapped where I spat from, and the third sounded me and listened as I spat. The first said I was dead, the second that I was dying and the third that I'm going to die.

One needs only to study a certain positioning of the hand in relation to the keys to obtain with ease the most beautiful sounds, to know how to play long notes and short notes and to achieve certain unlimited dexterity. A well formed technique, it seems to me, can control and vary a beautiful sound quality.

Among the numerous pleasures of Vienna the hotel evenings are famous. During supper Strauss or Lanner play waltzes...After every waltz they get huge applause; and if they play a Quodlibet, or jumble of opera, song and dance, the hearers are so overjoyed that they don't know what to do with themselves. It shows the corrupt taste of the Viennese public.
