"Everything depends, of course, on the shape of the hand, and it must be stressed that there is no type of hand which is more suited to the piano than another. One of the greatest pianists that I ever heard—certainly the most remarkable in his control of the widest possible range and variety of tone color—was Josef Hoffman, who had a hand so small that he could reach no more than an octave; Steinway built him a special piano in which the ivories were slightly narrower so that he could reach a ninth. His friend Sergei Rachmaninov had a very large hand, as did Rudolf Serkin, and Sviatoslav Richter could not only reach a twelfth but could play the last chord of the Schumann Toccata without arpeggiation—an effect which would certainly have astonished the composer. My teacher, Moriz Rosenthal, famous for his technique, had a small hand with stubby fingers; Vladimir Horowitz's fingers were exceptionally long, while Robert Casadesus had fingers so thick that he had trouble fitting them in between the black keys. There is no such thing as an ideal pianist's hand."
