This brings up an interesting question for me. For years I have played right hand chord and melody with left hand bass (like Uncle Dave?). I am interested in learning how to voice chords effectively with left hand to take full advantage of the arranger section of the keyboard. I am always blown away by the players who can voice chords and make the changes in the left hand at blistering speed, keeping up with even the fastest tempos. Any suggestions as to how I might pick up that skill?
