"I do not think that any composer has ever asked for octave glissandi on the black keys, but there is a recording by Moriz Rosenthal of Chopin's Black-Key Etude in which he plays the short octave passage in both hands glissando: it hurts my hands just to think about it."

“The relation of the performance of music to sound is complex and ambiguous: this is what makes possible Mark Twain's joke that Wagner is better than he sounds.”

“This is the true paradox of Chopin: he is most original in his use of the most fundamental and traditional technique. That is what made him at the same time the most conservative and the most radical composer of his generation.”

“Nevertheless, music will not acknowledge a context greater than itself—social, cultural, or biographical—to which it is conveniently subservient. To paraphrase Goethe's grandiose warning to the scientist: do not look behind the notes, they themselves are the doctrine.”

“We can, in fact, relive the history of taste in our own lives, the way embryos are supposed to go through the history of the evolution of a species.”

“Chopin's exquisite ear saved him from the ugly repetition of thick chords in the bass that frequently disfigure the work of Mendelssohn, Weber, and Hummel—and even of Field.”

“Music has its existence on the borderline between meaning and nonsense. That is why most attempts to attribute a specific meaning to a piece of music seem to be beside the point—even when the attribution is authoritative, even when it is made by the composer himself.”
