I sometimes play a harmony line on the english,I am sure its possible to play harmony on right,and chords on left,but remembering not to make the chords too heavy,perhaps dyads on the left, ist and fifth or ist and third etc..or even harmony on left and light chords on the right.depends also whether you have a tenor or baritone or bass voice,as to what one might do to effect contrast.www.dickmiles.com
