Why thanks Pippa.
It's been a bank holiday here in Holland so I've been spending too long with my new (30 year old Hohner) CBA.
Now I've got the hang of my first tune but it's going to be a long haul with the CBA as the keyboard logic is not hard wired in my brain like the PA.
I fear the CBA is causing me to loose neurons quite fast but by my calculation I should have enough to see me to the end.
It is rather interesting to play the PA then pick up the CBA and feel like a beginner again.
I am starting back from my first PA teaching books and using the tunes to learn the CBA.
I'm making up my own fingering and trying to get one tune a day under control.
Unfortunately as I start the second the first starts slipping away but that's a part of the game I guess.
