Pianos are mechanical instruments requiring maintenance to continue operating optimally and sounding great; you will derive far greater pleasure from a well-maintained piano. In order to function to the best of the piano’s potential, its mechanical components need to be aligned and attention needs to be given to the evenness of its tone. As an acoustic instrument made from organic materials like wood, leather and felt, pianos change constantly and are particularly sensitive to changes in humidity. When a piano is played, its felt hammers hit the strings and over time the hammers harden slightly which changes the piano’s tone and it can sound less sweet and even. Although most pianos don’t need to be maintained on a daily or weekly basis, they require more maintenance than is generally expected. And it’s important to remember that it’s not possible to over maintain a piano.
Tuning refers to the process of adjusting and correcting the pitch of each string so that melodies and harmonies played sound true and pleasing. An out of tune piano greatly reduces its musicality and diminishes the playing experience. Most pianos drift out of tune with time and changes in humidity. Pianos that get a lot of use also go out of tune through continued playing.
At a minimum, an annual tuning is advisable. It prevents the tuning drifting too far from true and gives the technician an opportunity to check the overall condition of the instrument and advise accordingly. On average, our regular clients have their piano tuned every 6 months. It’s also quite appropriate to have a tuning every 3 months to coincide with the seasons. By way of comparison, our performance venue clients have their pianos tuned once a week and concert pianos are tuned before each performance. You can’t tune a piano too often so tune when you think it needs it and at least once a year.
Every piano requires a different level of maintenance, depending upon the quality of materials used, the design and level of craftsmanship, the age of the piano, and the amount of use. As a rough guide, a piano undergoing light use should be serviced every 5 years, moderate use every 3 years and heavy or daily use should be serviced every annually or every 2 years. The service regularity also depends on the expectations of the pianist and the level at which it’s played.
Servicing involves adjusting the mechanical components of the piano, assessing and repairing general wear and tear, filing the hammers, replacing worn or broken parts, addressing any tightness or looseness of the moving mechanical mechanism and partially taking the piano apart and thoroughly cleaning it, for generally playability and to avoid fish moth infestation.
Regulation and voicing
You may have heard technicians refer to piano regulation, which is a broad term relating to any of the adjustments to the mechanism, keyboard and pedal system of a piano. Regulation is often performed as part of general servicing.
Another area of a piano technician’s work is voicing, which covers a wide range of techniques that are used to control the tone of a piano; for example softening the felt hammers to change the tone when they strike the strings. Voicing is arguably the most skilled element of piano making, rebuilding and servicing. Good voicing can elevate the tone of an instrument to its highest possible capabilities for expression. Bad voicing can destroy the tone utterly and ruin the hammers!
