Last year I was pondering about what instrument would be easy to learn.
After all your good advice I decided that there wasn't anything easy I should stick with my descant recorder.

It's the cold season again and I'm bunged up and breathless and looking for an alternative instrument again.

I thought that the only thing that would work might be an accordian, and I have seen some that are fairly small. Asking advice from an accordian player led to him arranging for me to borrow one ('only 72 basses'!!!!). This seems massive to me, I can't see over the top when sitting down.
The change in orientation of the keyboard (from a piano) is not the problem I thought it might be, I can get a tune out of it, especially if I stand up with the dots in front of me to remind my where my fingers are.
The bellows are a bit jerky (one week on), I stop pumping when wondering what note to play. And I haven't worked out how to vary the volume.
The left hand buttons are a complete mystery. I'd need a different mind set to play them.

My husband says 'why not get a spinnet or harmonium, then it would be the same as playing the piano?'
Does anyone know if such things are available, and fairly portable?
I don't want something I have to plug in as I want to play in pub sessions. Would a spinnet need tuning every time it was moved?
