I'm currently teaching myself how to play keyboards/piano and I'm making okay progress. I'll be spending a few weeks in the US this summer and there'll probably be a bit of jamming going on. Thing is, I won't be able to bring my bass along as it's too big and as I'm a lefty, I probably won't be able to use other peoples' basses or guitars. This probably means I'll be playing a bit of keyboards. There's one problem, though: I've yet to figure out how to play something bluesy that sounds good on my keyboard. Could someone give me a bit of a rundown on how to structure my chords when accompaning a garden-variety major blues? Should I play chords without thirds, for example? What are some good recordings to check out? Thanks a lot in advance.
