Temperature and the Tuning Fork

[Andrew and Rebeca Anderson]

I have one of those forks and I did calibrate it to my shirt-pocket 
temperature.  It seems to be the only way to "guarantee" as 
reasonably regular pitch (human bodies, barring illness, are finely 
temperature regulated).  What is interesting is how fast the pitch 
can change in a fork, particularly in a cute little thin one.
