When a technician completes a piano tuning, he or she adjusts the tension of each of the piano strings so that they sound in harmony with each other. A piano tuning consists of manipulating the pitch of the piano only. To change the tone of the piano, a piano voicing must be completed. To adjust other parts which contribute to the playing of the piano, such as the keys or hammers, a technician must perform action regulation on the piano.
While piano tuning consists only of this adjustment of the piano strings, our technicians are also qualified to do other maintenance on your piano, including piano voicing, action regulation, fixing sticking keys, adjusting squeaking pedals, cleaning and other more complicated maintenance tasks.
A piano voicing consists of adjusting the tone of the piano. This is mainly done by adjusting the shape and density of the hammer felts in the piano. If your piano sounds too bright, the sound may be mellowed by pricking the hammer felts to soften them. If your piano sounds too mellow or dull, the hammer felts are hardened by using a chemical hardener. The shape of the hammers also affects the tonal quality of the piano. If the shape of the hammers are uneven or indented, as is generally caused over time by the hammers hitting the strings as you play the piano, they may be sanded down in order to restore their optimal shape, and improve the tone of your piano.
Action Regulation involves adjusting the thousands of action parts on your piano so that the piano has the proper response to a player’s touch. This process includes adjusting screws and hinges, adjusting the thickness and density of felts located under the piano keys and on the dampers of the piano that may have become compressed with use and many more minute adjustments which can better the overall response of the piano keys and hammers.
