That was the big thing when I was growing up, singing on the radio. The extent of my dream was to sing on the radio station in Memphis. Even when I got out of the Air Force in 1954, I came right back to Memphis and started knocking on doors at the radio station.
I frequently compose out the entire metric structure of a piece in modified cyclic form, where each cyclic revolution undergoes some form of 'variation' much as if measure lengths were concrete musical 'material.'
