Hello David

 

Thank you for confirming that the piano is out of tune.

Could you please tell me what the maximum demand/stretch for double octaves
is?  I have an idea that it is anywhere from .5 bps - 1.5 bps, but from
reading the archives I am thinking that some folks stretch their tunings
beyond 1.5bps for concert grands in very big halls? 

Thank you, Mark.
