When playing an autoharp with three rows of buttons, regardless of the configuration of the chord bars, it is desirable to avoid having the fingers of the left hand get tangled up, or trip over one another. On a three-row harp, I try to keep each finger on my left hand confined to the chord bar buttons directly above and below the major chord bar button (which is my "home position") and use one finger for each vertical row of three chord bar buttons. This allows for faster chording and very little hunt-and-peck when changing to the next chord bar. Like touch typing, I try to keep the fingertip of each finger on my left hand barely in contact with the major chord bar button in any given vertical row of three buttons. This way (as in typing) I don't have to use my eyes to change chords.
