<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi all,<div>We've had a humidity "spike" in our recital hall the last week or 10 days. Every one is screaming that the keys are clammy, fiddle fingerboards are clammy and bowhair "skids rather than grabbing the strings". Yeah, yeah, yeah, the pitch of the piano jumped a few cents over last weekend, but nothing is screaming high humidity to me.</div><div><br class="webkit-block-placeholder"></div><div>The "spike"? We were up to a whopping 55% at one point, which by August standards would be a kiln. But we'd been running in the upper 30% to low 40% range fairly consistently until this "spike".</div><div><br class="webkit-block-placeholder"></div><div>Question is, why is it faculty and students seem to notice condensation on the keys if it gets over 48% in February, but if it's 75% in a studio in July, nobody mentions it?</div><div><br class="webkit-block-placeholder"></div><div>I understand walking out of a much cooler, drier hallway into the recital hall, which has humidification/dehumidification that is actually working, there is a noticeable difference in the feel of the air. But why is there a difference in condensation, or why is there a perception of clamminess now and not in August?</div><div><br class="webkit-block-placeholder"></div><div>Thanks,</div><div>Jeff</div><br><br><div> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div>Jeff Tanner, RPT</div><div>University of South Carolina</div><div><br class="khtml-block-placeholder"></div><br class="Apple-interchange-newline"></span> </div><br></body></html>
