Pitch Raising Techniques

[Richard Brekne]

I couldnt resist comparing the following replies to Quentins query, one 
from Ron Nossaman, the other from my good buddie Joe Garrett. While 
I'll  go along with Joe a short ways down the path he's on here, I have 
to mostly agree with Nossamans comments most.  Whatever the affect 
tuning one part of the piano has on another, its not significant enough 
to worry about IMHO.  At least not for the kind of pitch raises we have 
been talking about.  As with most things, a reasonably carefull approach 
that fits your own style best will do the job as well as any other in 
the end.  Sure, maybe some folks can cut 5 or 10 minutes from the total 
job that others cannot. But I suspect this has less to do with the 
specific routine involved, and more to do with a person who just plain 
works fast.

Quentin,
Yes, I've heard that. It is correct, in part. The Bass will effect the 
treble, but does not manifest itself in direct relationship with the 
soundboard as much as it directly affects the PLATE. This is why Dr. 
Sanderson came up with the technique of tuning from the bottom up. He 
detuned/tuned his wife's piano gazillion times and came to the 
unmistakable conclusion that starting from the bottom and tuning all 
unisons, as you go to the top, will give the most stable end result. I 
concur!
