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. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://ptg.org/pipermail/pianotech.php/attachments/20100209/f319f923/attachment.htm>
