pitch change

[Don]

Hi all,

Traditionally pitch change has been measured at A4 (and sometimes C), I
believe partly because of the contraints of tuning forks. Many of us now
use electronic aides which allow us the freedom to measure anywhere we choose.

Clearly the most unstable note on a piano is the lowest plain steel wire.
It would make sense to measure this note and its octaves.

Another "weird" note is the first string after the treble break. It behaves
differently than the note just below the break. Again, I extend by octaves.

These measurements give me a far better *feel* for the pitch  condition of
the instrument than measuring all the A's. The second measurement tends to
give me a *feel* for the design of the instrument and how this particular
piano will react to pitch correction.

I hope this may prove of interest to all VTD tuners.

I am curious if any aural tuners do these sort of "checks" and if so what
notes they choose.
