Birdcage pitch raise

[David Boyce]

I should mention that the birdcage piano I tuned is not really ancient. 
It's around 1915 I'd say.  I do take the point that a really old fine 
quality grand would need to be approached with caution respecting what pitch 
to bring it up to.

I'm not sure how I'd find out what pitch the birdcage in question was 
originally at.  English upright piano-making at the time still had a large 
"cottage industry" segment with lots of small workshops turning out cheap 
parlour pianos, made down to a price.  Whether the various workshops tuned 
to different pitches, I don't know.  Need to check Cyril Erlich's book and 
see what he says!

Best,

David.
