Pitch Raise Speed/etc., was: Steinway vs. The Tuner

[Farrell]

I agree that one will benefit from doing a separate pitch raise pass on a piano that is 4 cents flat (IMHO, even 2 cents). But that implies that when you adjust each pin, you will be getting the string pitch to within a cent of target.

I have been tuning for 4 years. I am still running at a steady 30 minutes for a fairly accurate pitch raise pass. My tuning time (tuning every string, i.e. not just a touch-up) is anywhere from 45 minutes on a real nice piano that has not wandered much to about 75 minutes on nasty consoles and the like. I read many posts on the pitch raise subject where it is said "no, no, no, don't worry about accuracy here, you are just trying to get the tension up" or whatever. Well, no, you are trying to get each string pitch to within a cent or so of target - or what? If I were just trying to get overall tension up, I could simply pull every tenth string 20 cents sharp - but I don't think that would be a great pitch raise.

Please, I am not trying to say that it must take 30 minutes to do a good pitch raise. I am posting this because I want to be faster. But I have a hard time understanding what I can do so very differently to go THREE TIMES FASTER.

And a second pitch raise topic here. I tuned a Yamaha C3 yesterday that was 3 to 5 cents flat (based on checking all the As and Ds). Another reason to do a separate pitch raise pass in this situation is that when the piano is this far off, there are likely other notes even further from target. A number of strings were 10 to 15 cents off, and one string on A#7 was 67 cents flat! I think it is analogous to the "where there is smoke there is fire" (sorry B. Clinton).

A third pitch raise topic here. I have never seen addressed the phenomenon of a piano below pitch dropping even more in pitch while pitch raising (hmmm....doesn't seem to make any sense). This especially applies to ETD users when calculating overpull. Let's say you have a piano that is uniformly 20 cents flat. Start pitch raising at A0 with your 17% and 25% overpulls. By the time you get to F5, check the pitch of the strings above F5 - they will likely be at least 30 cents flat, if not a bit more flat. So the question is then do you base your overpulls on an initial characterization of piano pitch, or on the next few strings as you go. I always do it on the next few strings as I go.

And a fourth pitch raise topic here........ Oh heck, I think I'll just go clean my shop..........
