Tuning from scratch

[pianotune05]

Hi Bob,
Have you tried the rubber mutes approach that Mr. Smith implimented for fine tuning after you use the temperment strips?  Some say that new guys like me should worry about that method,but I tried it on Thursday, and the piano sounded great. Fortunately, it was in tune enough that I didn't have to mess with the strip which takes  a lot longer than 40 sec. to put in place.

    Pitch correction is the same as tuning, only faster. Assuming the piano is flat, set the A about a third as many beats sharp as it now is flat, then use your normal tuning pattern, only force yourself to rip through it in about 1/4 to 1/3 whatever time it usually takes you to fine tune. If it doesn't come out right on, or average within about 1/2 beat per second in the temperament area, do it again until it does, then fine tune. If the strings are old, or the pitch raise is really huge, make one pass with very little or no overshoot, then see the above.
  I forgot two details - strip muting and the order of tuning. I prefer to strip mute with two strips (of action cloth, split down the middle except for an inch at the end), alternating notes through the triples. That is, the strip goes between unisons, but only every other one. The second strip goes where the other one didn't. In the bass, the strip goes every other space, muting the left string of one unison and the right string of the next.  On a grand this strip muting takes me 40-50 seconds, and saves lots of individual muting time. On an upright it takes a little longer. I 
  1. tune the center strings of the temperament, go to the bottom of the triples chromatically, then to the top of the piano chromatically. 
  2. I yank one strip, which exposes the left string of one note, and the right string of the next note, and tune. 
  3. Then I pull up the bass LRLR, then pull its strip, tune RLRL, 
  4. then yank the remaining strip from the triples and tune them.

  Your absolute timing will vary from anyone else's but should, as I say, be kept to about 1/4 to 1/3 of whatever it takes you to fine tune.
