Voicing (or tone regulation)

Voicing is a process whereby the felt on the hammer is altered in order to achieve a desired and a uniform tone from the piano. This can be done through needling as well as the application of chemical hardeners or softeners to the hammer of the piano. This process can do much to restore the quality of sound and is an essential step in hammer replacement.

It has been my experience that some of the more frustrating problems that pianists have encountered with their instruments are often the easiest to remedy. This is especially true with voicing. A few minutes of skillful needling can soften a hammer transforming a tinny annoying piano into a pleasant and enjoyable listening experience. On the other hand a muted piano with the same careful attention to firming the felt either through needling or the careful application of hardening agents can accentuate the tone of the piano delivering a fuller more vibrant sound.
