[pianotech] Double Octave Stretch

[Piano Boutique]

Mark,

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

  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.
