With the warm summer weather rapidly approaching, it’s not a bad time to revisit the topic of keeping your piano’s humidity at proper levels to avoid cracks in the soundboard, along with a variety of other performance and mechanical issues. As we’ve mentioned in prior posts, your piano should ideally be at a humidity level of 45% to help avoid problems caused by excessive drying of the wooden components of your instrument (which make up the majority of it!).

When out piano tuning, we’ll often see pianos that are placed in less than ideal spaces, often near fireplaces or other heat sources which contribute significantly to drying out essential structural components. Keeping a piano away from such places will greatly contribute to increasing its playing life.

It’s not only the larger structural parts of your piano that are affected by humidity. Overly humid conditions can cause your piano’s keys to stick, making playing difficult, not to mention annoying. The humidity levels also cause your piano’s pitch to change. High humidity will result in a sharper pitch, while low humidity will cause your piano to go flat.

A Humidity gauge is an inexpensive but important tool to have around to make sure your piano isn’t being exposed to extreme humidity or dryness. In our next post, we’ll take a close look at the options available to treat and protect your instrument from the dangers of humidity we touched on here.
