"The great privilege of musicians now in their fifties is to have witnessed at first hand all the works of Stravinsky as he produced them. In 1910 I was present at the premiere of L'Oiseau de Feu. After that we had to wait a year, more or less, to hear the next work. Every year thereafter Diaghilev brought us the new Stravinsky—always different, always unexpected, always more than exciting. From L'Oiseau de Feu to the extraordinary Orpheus that Stravinsky played on his piano for my wife and me in Hollywood in 1947, every work has its weight, its deep resounding in our soul. Each time different problems are involved, and each time their solutions are achieved in masterly fashion. I am thankful to be fifty-five years old and to have been able, for thirty-seven of them, to observe this prodigious production. While teaching at Mills College I had a tremendous experience which increased my admiration for Stravinsky (if that were indeed possible). I established a course of study in his music, and every Tuesday I analyzed, one after the other, all his works. To go through these scores, written between 1910 and 1947, is a real comfort for a musician and his students, united in their love of art."
