[pianotech] Pitch raise criteria

[Ryan Sowers]

I was a "three hour tune"r (kinda reminds me of the Gilligans Island theme
song!) for quite a few years in the beginning. After attending an all day
seminar with Jim Coleman, Sr. I wrote a letter to him telling him about my
frustration with how long my tunings were taking. I just couldn't believe
these guys who could tune a piano in an hour, or do a major pitch raise and
tune in an hour and a half.

 It seemed physically impossible!

Mr. Coleman wrote me back and said that the trick is to get so you can do a
10-15 minute pitch raise. By focusing on the speed of the pitch raise, he
claimed the whole tuning would become more efficient.

It changed my life! (corny, but true!!)
