Bill, I've heard countless jazz recordings where the piano is badly, sometimes egregiously, out of tune. Especially older recordings. I'm sure that the budgets and priorities were unfortunately different for jazz as opposed to most classical recordings. And probably most jazz pianists were pretty accustomed to encountering out-of-tune pianos in their usual playing environments as well, and so perhaps didn't (or couldn't afford to?) make a stink about it. I have a Donald Byrd album that the tuning is amazingly, distractingly awful on... So I guess at least some jazz players were being forced to experiment with unintentionally non-equal temperaments, but not ones you would probably call historic. "A-historic"? Prehistoric might be a better term. Allen Wright Oberlin Conservatory
