More on Pitch Raising
If a piano
- has not been tuned for a number of years (5 or more), and
- has never been on a regular (at least yearly) tuning schedule, or
- you have had trouble keeping it in tune, or
- you just bought it (used) and have no idea about its history,
then the chances are good that you will need a Pitch Raise
What's a Pitch Raise?
Hard, Cruel Facts:
- The more you do to a piano, tuning-wise, the sooner it will go out of tune again.
- Past a certain point of out-of-tuneness, trying to get a precise tuning all at
once is a waste of your money and my time.
- A piano reacts to tuning in two ways: Short-term and Long-term.
So clever technicians invented the Pitch Raise. The idea is to add a lot of change to
the piano in a hurry, before it has chance to get into its Long-term reaction. Precision
is not an issue, but the skillful part is guessing what the Long-term reaction is
going to look like and managing the Pitch Raise so that a month later, when the piano
is finished with the Long-term reaction, it will have landed fairly close to in-tune.
At that point, the piano is a candidate for a Regular Tuning, which whould then last approximate six months.
