Hi, Zach: My experience is that temperature is a huge factor in tuning. I don't allow any breeze over the piano when I tune, especially when I'm tuning an upright piano. If you take your finger and rub a string for a few seconds, you can measure a change in the frequency because of the friction and heat. I know some tuners on this list remarking that they open the piano first and let the temperature equalize before they tune an upright. Pianos are amazingly sensitive to temperature, and of course, humidity.

Dear Fellow Mailing-List Members- I am Zach LaMotte (current student at CSPT and newly applied associate member for the PTG!). After extensive research on past discussions in the forums, I have found a lack of talk on the effect of temperature on tuning stability. I am well-read on the impact humidity plays on the piano. I am requesting (kindly asking/begging) for any experiences, references, crazy stories, where any of you may have had temperature, not humidity, playing a factor on tuning stability. This could be an outside concert situation, stage light situation, mother-in-law making you raise the temperature in the house situation, etc. I will be conducting a temperature-based experiment and will share my findings once the experiment is finished. Thanking all of you in advance. -Zachary LaMotte "Aspiring Piano Tuner" -- Be Well, Zach LaMotte zachlamotte at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
