When me and Don and Hugh and Wayne made that record with Edie Brickell in the rehearsals and writing we would make a groove and it would feel good and then I might say we need a new part or we need to go somewhere else and she would then yell out a random note in her Texan drawl smiling “E flat” and we might sigh for a second if we were in D or E but then we would go to E flat and it always worked out. I realized then that if you are going to repeat anything and play it with confidence, it will be legit. I bet in the past some people were similarly confused [or acceptable] when composers inserted changes that had unexpected angles whether Thelonious Monk or Meredith Monk.
