The process of adjusting the tone(timbre) of the instrument.

As pianos are played the compressed wool hammer strikes the steel strings. Over thousands of strikes the wool will compress and yield to the steel creating a grove in the hammer.

As you have more material compressed into a smaller space the hammer will become brighter. Often described as bright or tinny, the process for softening hammers is simple and complicated at the same time.

Proper voicing of a piano includes reshaping the hammer to more closely resemble its original shape. We prefer to maintain the striking portion of the hammer as "egg shaped" or a fairly blunt point. This ensures that the hammer once it has struck the string will not in any way impede the proper movement of the string.

Brief Voicing Explanation

  1. Reshaping - the removal of layers of felt from the hammer molding to achieve the correct shape to the hammer
  2. Fit Hammers to Strings - the "leveling" of hammer strike point so that when the hammer is pressed to the string lightly and you pluck the strings, each string is muted equally
  3. Voicing - Hardening & softening of the wool felt to achieve uniform tone throughout the complete range of volume


Voicing is the most difficult and most personal aspect of piano service. Every pianist has a preference of the perfect tone. The best way to convey to us your piano technician is to find a few notes on the keyboard that you like as an example of what you would like the piano to ultimately sound like. Using these reference notes we can in most cases achieve the sound that you have expressed to us is desirable.
