Almost anything with strings that has to be fretted.

At various times I have had a go at guitar, lute and viol. In each case it was a disaster. Somehow I just don't seem to get strings. Piano and I did not really see eye to eye either, though I still have a keyboard which is useful for plonking out chords for tunes I write. Plonking pretty much sums up my standard of playing.

I am generally happy with things you blow or which make different notes on suck and blow. That seems fine to me. English concertina I did not really take to but the Anglo I was getting tunes out of in a fairly short time.
