[pianotech] Pitch raise criteria

[Joe Goss]

Hi,
Each time I read others comments on pitch raising I am reminded of the futile attempts and outright failures in my attempts to do a 10 minute pitch raise. Each time winding up with a piano that after the pitch raise needed two to three more passes to be considered (in tune).
So, being a rather lazy fellow, and using a SAT ll or lll and the bass over pull  the Verituner uses  it is usually, on most pianos, a very deliberate first pass followed by a much quicker second pass.
Wound strings 12.5% over pull Read A2 and divide by two, enter.
Tenor spinets, and especially plywood boards 20% all others 25%
Bb4 or C5 25%  Re cal at the treble break and sometimes at F6 
Second tuning usually will be the tenor to C5 but at times its the whole piano. Always under two hours.
The above is done with a wide rubber mute and the spring steel split mute. This mute works like the pap mute without the metal attack.

  The main thing is to not care too much! Do not get hung up on accuracy AT ALL. If you feel like you pull one note up too far, instead of fixing it, just don't pull the next one up so much. This will help compensate. GO GO GO!! That's the way to do it. Get into a rhythm. Timing yourself can be very useful. 

  Give yourself about 3 seconds to tune each string.This will come out to about 10 minutes. 4 seconds per string will put you at about 15. 

  I don't strip mute. In fact, my muting technique is probably not very efficient - I just use a couple pair of rubber mutes. 

  Just get it done!!

    OK - I heard this so many time before - but - exactly - how - do you do it.

    Exactly - how do you know what the - target - pitch is -- or are you
    guessing ?

    Technique, mutes, no mutes, strip, no strip, etc.
