Hi Dennis,

In my effort to not confuse non musicians in my earlier posts I just used
letters, and then perhaps didn't explain fully how I crossed over to key
transposition.

Yes I agree using my method for inversions is a bit strange, I'm sure I had
a reason for it, but it's late here and for now I can't remember what it was
at the time : )

Thankyou for your code. Key transposition is what I was after. I appreciate
it.
