No, I meant exactly what I said: 3/9. That's what Playford used to begin with, though after a few years he moved to 9/4. I expect he had what he saw as good reason for that; I don't understand musical theory sufficiently to guess why. What we see nowadays as unusual or exotic wasn't so very unusual in the past.

Not 9/8; that's a more recent approach, though certainly the way we'd notate (and play) it nowadays.
