George Gershwin once considered taking lessons from Igor Stravinsky. "How much will you charge to come over and give me lessons in orchestration?" Gershwin asked. "How much do you make in a year?" Stravinsky inquired. "A hundred thousand dollars," Gershwin replied. There was a long silence, finally broken by another question from Stravinsky: "How about you giving me lessons?"
[A similar story is told of Gershwin and Maurice Ravel (with Gershwin in Stravinsky's role).]
