Terry: Today I tuned a Baldwin Studio Hamilton Piano to A440. It was at least 1/4 step below pitch. Here is how I did it step by step: First Tuning Tuned mid section to C526.3...(3 waves above pitch) raise each octave 1 beat above this pitch...tune bass same pitch as mid section....10Min....just get close. Second tuning Tune entire piano to C523.3...A440..Set Temperment...(recheck tweak) tune octave & unisons..proceed up the piano rechecking octave and then if necessary Tweak final tuning as you recheck...then tune bass rechecking as you did in the treble...finally tune the mid section unisons, recheck and tweak if necessary. The piano has been either tuned or rechecked 3 times when you are finished. The tweaking If necessary is on the final tuning. As Bill said, one can tune a piano quicker and more accurately by not fighting the instrument. I finished this process in approx. 40-45 Min. I'm sure this is no great revelation but I do hope this might help someone. Remember the trick is not getting perfect the first or even second time....the final recheck must ...must be perfect. You have three shots this way. Since I tune aurally I'm sorry I cannot talk in terms of cents. Tommy Black Decatur, Ala.
