Can Humidity damage my piano?

Hello Piano Players and music lovers.  This blog is about the effects of  Humidity, the lack of enough humidity, and the changes in Humidity on a piano.

High Humidity

High humidity does two things to a piano.  Its causes rust and causes the wood to swell.   The Main parts rust affects on a piano is the strings.   The tone is affected by rust on the strings.  This happens usually in pianos subjected to a lot of high humidity.   It is also common on old pianos.   Rust on strings also causes what is called false beats.  This is where one  string sounds like it is out of tune.  This will affect the higher strings more though it can affect the middle of the piano.   When tuning a piano like this we can make this problem a little better by using phase cancellation.  If the high end of your piano sounds like it is not in tune as well as the rest of the piano right after a tuning,  this is why.   Note:  right after tuning.  The high end usually is the first part to go out of tune because the strings are shorter.

How long does a pitch raise take?

A pitch raise is essentially a special tuning procedure designed to leave the piano approximately in tune. For moderate pitch corrections the procedure takes about the same time as a tuning, or less. Extreme pitch changes may require two separate pitch adjustments.

The pitch adjustment and subsequent tuning may be done in one visit, or the tuning may be scheduled for a short time later depending upon how far the pitch had to be changed. In general, the longer a piano has gone without regular service, the more tunings will be required to reestablish tuning stability.

 

Like your car, your piano is a major investment which deserves regular servicing to keep it working well and preserve its value. Most importantly, the well-maintained piano sounds better, plays better, and gives you and your family a wealth of musical pleasure.

If your piano has not been tuned in the last year and is more than 5% off pitch, it may need what is called a pitch raise. This re-tightens your piano’s strings and allows it to hold the fine tuning.

Will tuning my piano restore it’s pitch to A-440?

If a piano has gone without tuning for an extended period, its pitch may have dropped far below A- 440. This means that each of its approximately 220 strings needs to be tightened considerably, adding tremendous additional tension to the piano’s structure.

The problem is that as each string is tightened, the additional load causes the pitch of previously adjusted strings to change. Thus it is impossible to make a substantial change in pitch and end up with a fine, accurate tuning in one step. Instead, a process called “pitch raising” must first be done, in which all strings are raised to their correct average tension levels. (Likewise, when a piano’s pitch is higher than standard, a pitch lowering procedure must be done to reduce string tensions to approximately correct levels.) Only then can the piano be accurately tuned. In other words, accurate tuning is only possible when all strings are so close to their proper tension that only small further changes are needed during tuning. These small changes then do not disturb the tuning of other strings.
