Humidity in Your Piano

I’ve been to quite a few different towns recently, and had to do a bit of pitch-correction on some of them.

What does this mean?

We usually tune pianos to standard pitch, “A440”.

But if the piano is flat or sharp, we first need to do a pitch-raise or pitch-lowering, and afterwards a fine-tuning.

   With all the rain lately, the wood of the soundboard and bridges on the soundboard, where the strings cross over, swells, making them to stretch, and therefore, raising the pitch.

   Usually with the cold season, the pitch drops, and with warmer weather, pitch goes sharper.

So you don’t want to drop the pitch too much, because the cold is coming, and pitch might drop even further than you intended.

   That is why you need to have your piano tuned frequently, at least once a year, but preferably, twice a year.

And keep your piano away from cold draughts, open doors and windows, heaters, fire places, isolated from the weather.

   Idealy, humidity levels should be between 45 and 55 percent in the room, but just keeping it away from doors and windows already helps.

This is what they actually mean by saying:

“Don’t put a piano against an outer wall.”

Because outer walls usually have windows and doors in them right?

We often find pianos standing right in the entrance hall of a house.

It’s better to keep a piano, for example, in the living room, in a corner where there is no window.

   You also get humidity control systems you can have installed inside of your piano, which can control the humidity levels inside.

But just servicing and tuning your piano frequently helps.
