[78-L] Concert pitch (was: no subject)

[DanK]

My Foster player piano has 2 notes inside - one is the manufacture date of 
April 1917, and the other is that "This piano was tuned to A440 at the 
factory" .  It had dropped considerably lower by the time I bought it, but 
my uncle the piano-tuner brought it back to 440 without trouble (after I 
laboriously twisted the dead bass strings, bringing them back to life)

That's good to know, thanks! Fits well with my observation that pitches 
converged more and more towards A=438 to 440 Hz after WW1. The wildly 
varying pitches listed in my last message belong to the pre-1914 period, 
sorry for my negligence in not making this clear.
