Greetings List, I have read much about piano tuners preferred octave stretch. I recently came across a grand piano in a fairly large school hall which had been tuned two weeks prior to me inspecting the piano on request. The octaves were stretched 1 bps and the double octaves were beating almost 7bps. Rick Baldassin writes in his book "On Pitch", pg 83.84,85. 'There are widely varying opinions as to where and how much to stretch octaves, and rather than impose my personal opinions, I choose to present facts and tests that will allow each reader to experiment and create his or her own opinions as to how and where stretching should be done. After all, in octave stretching, what we are dealing with is often more a matter of artistic preference in a grey area than random selection in black and white.Remember that when stretching the octaves, the demands of the double octaves must also be met.' My questions are, what are the demands of the double octave and what is the maximum stretch one can/does use in a big concert hall, once again considering the double octave demand? In other words how much stretch is to much and the reasons why? Thank you, Mark Davis -------------- next part -------------- An HTML attachment was scrubbed...
