Mock tuning test ??

[Avery Todd]

Hi Jim,

    This may be true but since I've been giving the tests, I've found that the
amount of the detuning contributes to an unstable tuning afterwards. After
I use our test piano, I find that I need to go back and retune it within a 
short
time (it's in a piano teacher's studio). :-)
    I've wondered why this instability factor was not considered. Or was it? It
seems to me that it's similar to a pitch raise or lowering job. The strings are
not stable even though the soundboard might be (in the test detuning).
    Just a couple of random 'wonderings'.
