Ever the sage elder statesman, Sonny Rollins settles this in an essay from the New York Times.
There’s an axiom that says there is no such thing as “original” music. After what we could consider to be the first sound, from a spiritual perspective — “om” to some, “amen” to others — it’s all the same. Musicians borrow different parts and make them their own, but there’s nothing really new, nothing that hasn’t been done before. Claude Debussy and Johann Sebastian Bach may sound different, but what they did was all there already, in a sense.
