True, but the poor sod's only just got it! Scales on the bass buttons after a week? Martin, I can't play accordion at all, but my old flatmate was rather good. This is how he did it.

(C,D,C counterbass,F,G,F counterbass,G counterbass C)

And the pattern is the same on a 120 Bass for whatever key you start in. Thank you mr Stradella.

Obviously your knackered for minor scales though.

Cheeeeeeeeers
