Barry, another masterpiece. This one really brings home your mantra about being true to the melody of a song. The melody dictates everything in this song. The dorian sequences was such a valuable insight. I actually did some research and found this excerpt here: https://www.jazziz.com/a-short-history-of-ceora-lee-morgan-1965/
Jeffrey S. McMillan writes in his book DelightfulLee: "The Life and Music of Lee Morgan, that the song’s “beautiful melody jumps and soars over a relaxed harmonic rhythmic context of elegant sophistication,” and that “many students of the music to living legends like Harold Mabern and George Coleman continue to perform it regularly.” McMillan also interestingly traces the origins of “Ceora” back to the ballad “If Someone Had Told Me,” composed by Peter De Rose and Clarence Tobias, who were popular songwriters of the 1940’s and 1950’s."
I can't verify the claim, and I always think we probably overanalyze the motivations of some of the greats. Who knows? Lee was probably just exploring changes without being academic. Anyway, the result is what counts, and, as usual, you did it justice and showed it for what it is . . . a beautiful classic. Thank you.
