How to Fix Sticking Piano Keys in Michigan

Sticking keys or a note that plays one time but then will not allow repetition of the note are sources of frustration for all levels of players. I have heard countless frustrated mothers explain the reason her child stopped taking lessons, only to tell me her next child just began taking piano lessons and she wants the piano tuned. As I begin the tuning process it soon becomes apparent why the first child quit, and will be the reason the second child will quit. On the other end of the spectrum the high level player will walk away from the piano, and won’t touch it again till the problem is corrected.

In an attempt to keep this article user friendly I am going to touch on two of the causes of the sticking/sluggish note. First is verdigris which is a contaminate that can be seen as a green moldy looking substance that causes the action flanges to pivot slowly, and in severe cases not at all. The photo below shows a action flange with verdigris:

Second cause is humidity level changes that cause the small wooden parts of the piano action to expand or contract causing the action parts to bind:

Please take a look at my video, showing the repining of the action flange that was sluggish as a result of verdigris:

This approach is highly effective and can be performed on two or three notes that are a problem or the entire action can be repined.

In the case of humidity related malfunction, humidity control is the most effective and lowest cost approach. Things like humidifiers on the furnace, digital hygrometers, air conditioning in the summer months, and in some cases the piano life saver, also known as the Dampp-Chaser system are the first line of defense in preventing and reversing the effects of high or low humidity on your piano.

Each piano must be evaluated and then an approach can be custom tailored to fit the piano’s specific situation. I service pianos in the Oakland County Michigan area, and would love to help you with your piano service needs.
