I play very badly and don't attempt to convince the customer that I am an artist. I do however have several things that I do to check out the end product after a tuning. I can play arppegios, and two or three recognizable tunes. This has always seemed to safisfy the customer. I never ask a customer to play the piano for me after a tuning. I don't need to spend the time while they get out their favorite sheet music or hymnal and go through whatever routine they are comfortable with. I know the piano is in tune, and they should be able to trust my tuning. I remember an adage given to me by a piano salesman who didn't play. "If you went to a store to buy womens undergarments, would you expect the salesman to be wearing womens undergarments?"
