Mark, Try tuning it sharp enough so that your fifth, or 17'th is smooth.

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/20100210/4647a6b6/attachment-0001.htm>
