"Some of the Etudes in the first set, opus 10, were written by the time Chopin was twenty. It is with these pieces that Chopin's style was fully revealed in all its power and subtlety. Later works are sometimes more ambitious and, in a few cases, more audacious, but there were no radical changes of style, nothing to compare to the later revolutions we find in the careers of Haydn and Beethoven, or even in the shorter lives of Mozart and Schubert. Chopin's mastery was proven with the twelve Etudes of opus 10."

“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.”
