Thank you for responding.

Well if I were to make my own best estimation of what's happening it would go like this:

The piece is indeed in the key of C but, in a move that is a bit unusual for me, it starts out with a Dm7 and resolves at the end to a C6 instead of a regular C major (I did not include the end in my original message). This is unusual to me but may be something common to the Jazz idiom. I don't know.

But even with the above stated, it does something predictable for me and that is to follow the circle of fifths back around till it finally resolves, in the end, to the C6th already mentioned.

Pleasant to hear and play. Just a little out of my normal repertoire - which is good. I need to be more eclectic in my music choices and what I play.
