Sam,
I have very small hands. My father played guitar and he has small hands. So when you have these types of chords I can't hit them. Are there any chords I can substitute these for to still get the full effect of them?
How would I split the right hand to play with both hands and still play the bass on a keyboard??
The L.H. shouldn't be that hard. Sam's playing power chords (using the 1 and the 5) or he's playing the dominant 7th shell ( the 1, 3, b7). Now, if your hands are too small for the shell, then stick to the power chords.
As for the right hand, what
I do is eliminate some of the doubled notes. For example:
Sam's chord:
G D / A B D Gb B
Jonathan's version:
G D / A Gb or G D / A B D Gb (I would play the A & B with my thumb.)
Play around with the chords and see how using my variation works for you. It's all about finding a comfortable feel for you.
How'd I do, Sam?
