Pitch Raising Techniques

[Richard Brekne]

Hi Quentin.

I have heard so many different <<theories>> about what does and doesnt 
happen to the piano during pitch raises I could write a medium size book 
about it :)  Well, ok thats an overstatement... but just so.  I have yet 
to find any one particular of these shown to be true, and personally 
believe it doenst really make any real significant difference which way 
you go about it.  I find that starting in the middle and working 
outwards both ways works well for me, but I think thats more a matter of 
what I am most comfortable with then anything else. In the end, as long 
as you dont get into any draconian proceedures I think you are pretty 
safe from doing any real damage to the piano.  If you are raising pitch 
300 cents or so... well then perhaps you might want to raise things a 
bit more evenly... just to be on the safe side.  But for usual piano 
work I think most of these kinds of concerns are rather overstated.

Cheers
RicB
