Angel In My Life

From The Real Frank Zappa Book (1989): "Mr. Kavelman, the band instructor at Mission Bay High, gave me the answer to one of the burning musical questions of my youth. I came to him one day with a copy of 'Angel In My Life' -- my favorite R&B tune at the time. I couldn't understand why I loved that record so much, but I figured that, since he was a music teacher, maybe he knew. 'Listen to this,' I said, 'and tell me why I like it so much.' 'Parallel fourths,' he concluded."
