Starting Pitch chart

[Cy Shuster]

It's a great idea, Greg; thanks for sharing (I love your sharps at the top; 
helps communicate very well!).  I've been doing it for a couple of years.  I 
just measure each "A" using TuneLab, against the curve I've calculated for 
that piano.

I've found that it really helps the customer understand what we do when we 
tune, and how the piano's condition and environment contribute to tuning 
stability (or not!).  Instead of thinking of tuning as just binary ("in 
tune" or "out"), it's more like tracking the wear of the brake pads on your 
car (where you get a report of % of pads remaining), or even having your 
teeth cleaned.  Some people can go once a year to the dentist; others need 
four times a year.  It gives the customer something concrete to evaluate 
your recommendations for tuning frequency or humidity control.

I've even found repair problems by tracking pitch like this.  I had a C3 in 
a college that had a lot of pitch variation in octave 6.  It turned out to 
be loose bridge pins.
