[pianotech] Tuning speed

[Leslie Bartlett]

I use TuneLab, and guess at 3-cents I can learn to do it that quickly. At
10+I'll do it twice.  Below about 20 I start in the last section, then go
through the whole piano twice. That's 2-3 passes and two hours, except for
those horrible Chinese pianos, and I've never seen one of those I can tune
in less than 2.5 hours..

thanks

Les I should have elaborated more. I use a Cybertuner and the "smart tune"
feature calculates the over pull for every note from the inharmonicity
readings taken before starting. For a piano up to 25 cents flat one pass and
tidy up a couple of unisons is the norm. My tuning time is normally around
50-60 minutes. If doing a concert tuning even a raise or drop of 3 cents
benefits from the over pull calculations. The ETD knockers should spent a
bit of time and see how good this program is rather than saying aural is the
only way.

When I first started tuning (48 years ago) my tuning time was 1.5 to 2.0
hours. I then though if I really concentrated on setting the pin in two
movements it would shorten the time. So I make it a challenge to only move
the hammer only twice for each pin. If I overshot on the second movement I
would try harder on the next pin.

So you're saying that you can to a 15 cent pitch raise in only two movements
of the pin?   How to you gauge the amount you over pull to allow both for
the out-of-tune-ness as well as the inconsistency of the pins, and of each
individual string?  This is completely baffling to me, especially when I
tune more than a few concert level pianos.   I have some Chinese pianos
which are so ghastly that they are 2.5-3 hour tunings..
