I don't really consider I have a LH and a RH. Just TWO hands. Both equally important.

So, I do quite a bit of swapping sounds away from their usual hands. Keeps you on your toes. Some songs, I do piano in the LH, brass in the right, then I'll swap the sounds, and do it with brass on the LH, and piano on the RH.

No rules, no limitations...

Sure, I can do bass with the LH, but sometimes it's FUN to do it with the right. Especially where, say in reggae, the bassline actually IS a melody, but the accompaniment is pure simple repetition.

BTW, accordion has the CHORDS on the LH side too! And play an electronic or MIDI accordion, either side can play anything! No rules... LOL

BTW, ever see Joe Zawinul's 'reversed keyboard' thing? He had some keyboard (I think the Oberheim's could do this) where he reversed all the notes. High notes were on the left, and went DOWN as you went right. Trippy, trippy stuff! You just played some of your usual licks and riffs, and got utterly fresh, exciting and new results, and it freed your mind!

No rules... is good rules!
