Wolfgang Amadeus Mozart,
Mozart: The Man and the Artist…
“ Herr Stein sees and hears that I am more of a player than Beecke,—that without making grimaces of any kind I play so expressively that, according to his own confession, no one shows off his pianoforte as well as I. That I always remain strictly in time surprises every one; they can not understand that the left hand should not in the least be concerned in a tempo rubato. ”
