Why do we need piano tunings, regulation, voicing and other adjustments?
Piano Tunings
With around 10,000 individual parts, pianos need regular maintenance as it adjusts to the changing humidity levels throughout the year. Made mostly of wood, humidity causes the piano to expand and contract, subsequently knocking it out of tune as it changes the tension in the strings. In general, tunings are suggested twice a year, after the changes of hot and cold seasons. If the piano is heavily played, more tunings may be needed. If moving, wait two weeks for the piano to adjust to its new environment before getting it tuned.
Pitch Adjustments
Depending on how out of tune it is, the piano may require an extra round of tuning, also known as a pitch adjustment. Measurements will be taken to determine if the piano is 5-8% out of tune. If so, a pitch adjustment is often necessary to equalize the tension of the strings around concert pitch before a fine tuning can be completed. Pitch adjustments are completed in the same appointment as the tuning. In essence, it is a double tuning. Pitch adjustments are often needed if the piano hasn’t been tuned in over a year. Double pitch adjustments are often necessary when pianos are over 50% out of tune, for example if you play the note C but it sounds like a B.
Repairs
Over time the piano accumulates wear and tear from use, and parts must be replaced or repaired. Wood and felt become brittle and compacted, strings break, and contact points in the keys and action need lubrication. After a thorough evaluation, suggestions will be made as to which repairs would best enhance the playing experience. Work will only be done with the owner’s approval.
Regulation
Regulation refers to the adjustment of the mechanics of piano, in order to improve the playing experience and control over over the sound produced. After prolonged use, all pianos can benefit from regulation as various parts suffer from the wear and tear of playing, as well as the misalignment of the moving parts. Even new pianos can benefit from regulation as parts will often settle and compact during the first year. Regulation will address issues of touch in the keys, control over soft playing, quick repetition of notes, faster playing and the range of dynamics.
Voicing
Voicing concerns the tone of the piano, which is determined by the condition of the hammers. Made of felt, the hammers often become deformed and compacted from playing, resulting in a harsh tone with a limited range of expression. Using various techniques to reshape and soften the hammers, the piano’s tone can be revitalized. Hammers can also be too soft, resulting in an unfocused mellow tone. Filing and applications of lacquer can brighten the piano’s tone and give it more volume. When voicing is not a viable solution, hammers should be replaced.
Dampp-Chaser Humidty Control System
For pianos that have trouble staying in tune because of environmental conditions, the Dampp-Chaser Humidty Control System is highly recommended. Combining the effects of a humidifier tank and dehumidifier rods, a humidistat regulates the system so that the piano is maintained in the ideal range—ultimately resulting in more stable tunings that last longer throughout the season. As a registered Dampp-Chaser technician, I install systems for both upright and grand pianos.
