I don't think thickness of the board has much to do with it either. There do seem to be some models that move more and faster in response to a humidity change, but I haven't found that this is very predictable, and certainly not relative to "high versus low quality/price point." I think the biggest factor is idiosyncrasies of the particular stringing scale (and the factor that leads to tuning instability may have other positive effects).</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>One thing that does seem to lead to a bit more tuning stability sometimes is age - older boards and bridges maybe are less sensitive, I suspect.

Depends on our total hours as opposed to number of pianos, and what priorities we set. Concert instruments get highest priority, and get tuned very often, because they need to be as near perfect as we can get them, every single unison all the time. The number of tunings given to any individual piano is dependent mostly on how critical it is, not on how sensitive it is. </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Tuning stability is lower on my list than tone production and quality, and action responsiveness. The piano needs to be capable of making music. Tuning takes a lot of our time, but is not the most important thing we do. An institution that focuses on number of tunings to design its piano maintenance program needs to talk to somebody who knows a bit about comprehensive service.</div><div><br class="Apple-interchange-newline">Regards,</div><div>Fred Sturm</div><div>University of New Mexico</div><div><a href="mailto:fssturm@unm.edu">fssturm@unm.edu</a></div><div><br class="webkit-block-placeholder"></div></div></div><br><div></div></div></body></html>
