Hello Patrick, If it is a regular Mason then tune it like any other. If it is a screw stringer then read Susan Kline's article in this months Journal. I just got mine today. You will ned a Mason & Hamlin wrench if there is not one with the piano. THey are available from the supply houses. Trun the screw down until the pitch changes then turn it up slowly to the point you want it then stop. If you over shoot do it again. Newton
