if it waz ever in doubt - herez definitive proof he waz a mofo :
“For a whole fortnight my mind and my fingers have been working like two lost souls. Homer, the Bible, Plato, Locke, Byron, Hugo, Lamartine, Chatéaubriand, Beethoven, Bach, Hummel, Mozart, Weber are all around me. I study them, meditate on them, devour them with fury: besides this, I practice four or five hours of exercises (thirds, sixths, octaves, tremolo repetition of notes, cadenzas, etc). Ah! Provided I don’t go mad you will find in me an artist!”
