Thank you all for your help. "Filling in the holes" cuts right to the heart of it. Thanks, Don, for the specifics, and I notice you always fill yours real good. One question is: To what extent is it permissible to duplicate the melody line? The easiest thing for me to do is sing in the same time as I would play, jumping the beat or lagging like Sinatra, to give it a live feel. I most always use full left hand sound for movement to fill in with like a ninth/-9/major. I just don't want to do it if it is going to sound amateurish.
