Pitch raising technique

[Joe & Penny Goss]

Larry,
Try taking a reading on A2 if the pianer is about 50 cents flat.Then tune
from A0. This will give a smaller percent of pitch raise to the A2 area and
the low bass will most times fall close to where it needs to be.
Reset the pitch raise at the first unwound string and again at the bridge
break and sometimes earlier if the piano is losing pitch too fast. One can
also get arround this by letting the lights move increasingly to the sharp
side
just before the breaks.
