No, I don’t. In fact it has been such a lack that started me thinking along the lines of building something. So I modified my string test fixture and have been investigating the relationship between strings and soundboards with varying amounts of crown and string bearing. What I’m finding—at least what I think I’m finding—is causing me to rethink much of what I thought I knew about this very interactive system. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 — Cell 360.388.6525 <mailto:del at fandrichpiano.com> del at fandrichpiano.com — <mailto:ddfandrich at gmail.com> ddfandrich at gmail.com From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of Alan Eder Sent: Friday, May 11, 2012 2:09 PM To: caut at ptg.org Subject: Re: [CAUT] Fwd: Mason & Hamlin soundboard model with tuning fork Got it, and thanks for the explanation. Is there any simple demonstration model that can readily A/B the effects of crown (with its attendant resonance/sustain and power/projection) vs. no crown, preferably on the same piece of surrogate soundboard? That is what is really needed to faithfully get the point across.

This is not how piano soundboards are crowned nor is it how they work. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 — Cell 360.388.6525 del at fandrichpiano.com <mailto:del at fandrichpiano.com> — ddfandrich at gmail.com From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org <mailto:caut-bounces at ptg.org?> ] On Behalf Of Alan Eder Sent: Friday, May 11, 2012 11:48 AM To: caut at ptg.org Subject: Re: [CAUT] Fwd: Mason & Hamlin soundboard model with tuning fork By no stretch of the imagination it is my personal call what to include in the final cut of the film, but I am very interested in your critique of the phenomenon this model is designed to demonstrate, and would like to see your perspective integrated into the discussion.

Most of the shooting is already in the can, but we are still getting some pick-up shots. In order to demonstrate the need for crown in a piano soundboard, we would like to use one of those Mason and Hamlin demonstration models in which the mini-soundboard can readily have crown added or taken away, to demonstrate the pronounced difference presence or absence of crown can make. Anyone who can provide us with such a beast will be properly compensated with our undying thanks and a Reward In Heaven.
