(And this)
"Favreau, a self-taught pianist who studied classical music in college, delights in the comparison of his work to pop song writing. “A good line in a speech is like a good piece of music,” he said. “If you take a small thing and repeat it throughout the speech, like a chorus in a song, it becomes memorable. People don’t remember songs for the verses. They remember songs for the chorus. If you want to make something memorable, you have to repeat it.”
