“In playing for contemporary composers, I’ve always felt that the ones I respected were not inflexible about what you did to their music. They permitted a certain degree of freedom. I’ve found that the lesser composers were the ones who insisted, no, I said mezzo piano and that’s not my conception of mezzo piano. I think the great composers believe their work will endure even if one does not adhere to the exact indications of the music.”
Isidore Cohen (quoted in Nicholas Delbanco, The Beaux Arts Trio: A Portrait)
