In response to Ed Gloeggler's request on piano and Violano humidity control in regard to tuning etc. Ed tells us that his Violano drops and raises in pitch more or less evenly according to humidity changes. The problem is quite normal, but few persons notice it. Other than a few select piano owners ...

I have noticed over the years that Violanos will stay in tune better when their light is left on and things are kept at a relatively constant temperature. Humidity changes in a room is also moderated somewhat by the higher (maybe 2 degrees max) temperature inside the case. Keeping another small 40 w...

•Humidity fluctuations are more damaging to a piano than temperature changes. It would be an ideal situation if we could control the temperature and humidity surrounding our pianos. Unless we are wealthy enough to afford a climate controlled room, our only choice is to do our best and make an attemp...

•Both the Piano Technicians Guild and the Steinway Web Sites discuss relative humidity. Quoting from http://www.ptg.org/care.html - "A piano functions best under fairly consistent conditions which are neither too wet or dry, optimally at a temperature of 68 degrees F and 42 percent relative humidity...

•Those of us who are required to heat our homes or shops in winter should keep a humidity gauge, and read it daily. We will soon discover that there are drastic changes between natural summer heat, and winter's artificial heat. In my home, on the waters edge of lake Cayuga, humidity in summer can be...

•I recently commented that a newly installed Dampp-Chaser in my neigh- bor's Kawai grand piano started the piano to "oinking" on a couple of dozen notes when the dampers re-seated onto the strings. The problem has almost been completely resolved, but there are still some stragglers "oinking" just a ...

•Hi All, Don't hate me for this, but something Bruce Clark wrote made me chuckle. He wrote, "This drastic change is very unhealthy for your piano, you, or anything made of wood." Yep, at times us player techs can be real block heads. ;-) Don't forget to drink 6-8 glasses of water a day. :-) Seriousl...

•I am addressing Andy Taylor who bemoaned the winter loose pins from lack of humidity. All pianos are affected by humidity fluctuations. The most often affected is the soundboard and its crown. If you ever wondered why the piano went out of tune in one section but not another, consider when a soundb...

•This topic makes me squirm a little. I am in England in a house built in 1900 with solid 9-inch brick walls (no cavity gap). We have been here 10 years and have no air-conditioning which is usual in almost all private homes here in UK (and cars). When the windows are closed during the winter months...

•After all the horror stories about humidity and pianos in the USA I'm glad I live in England where our climate suits pianos just fine. Gives the people lots of sneezes, coughs and blocked sinuses though. Jeffrey Borinsky

•Last winter, I became curious as to what kind of humidity systems were installed in rooms with hot air heat and what levels of humidity were being maintained. So, I conducted a survey of a number of the major collectors and restorers. The two primary means of adding humidity in the winter are syste...

•I'm looking at humidity control solutions for my player grand piano and my search includes the Dampp-Chaser. Does anyone have any experience with that brand? Any problems or kudos? Any additional humidity solutions anyone can offer? Thanks. Paul Johnson [ See "Relative Humidity and the Piano" by Da...

•This is a very tricky subject. I am a museum professional with experience in most areas of conservation. Relative humidity is very important in the storing, display and the control of deterioration of all historical objects. The most important point is not to have huge fluctuations in either temper...

•We have had a very humid and somewhat warmer climate in southeastern Norway the last months. The humidity is usually at 50-60% in the summer when it doesn't rain, however it has been 70-75% most of the time, causing my Duo-Art piano to be somewhat out of adjustment the last months. It keeps well in...

•I feel I must take issue with Jonathan Holmes' reply concerning the Dampp-Chaser. This is a total humidifier/dehumidifier system which I have seen work miracles in helping to maintain constant temperature and humidity in a piano. What he describes sounds like a heater bar, and in no way describes t...

•It isn't possible to keep insects out of a player piano if they want in, but it is possible to discourage them just a little. In the first place, insects don't like an instrument that feels as though it is a different temperature than the rest of the house, as this is an indication to it that the b...
