So many piano players do seem to stop once they've learnt those three chords and yet a good player can really lift the sound. I spent an evening at a dance near Boston listening to the playing of Jacqueline Schwab and was entranced by her music. Peter Barnes is another whose playing lifts the sound. Andy Thorburn does similar in Scotland. But the Dum-chinging piano sound either has me switching off or going somewhere else. Unfortunately most Scottish dance bands seem to like Dum-Ching.
