A piano should be tuned at a minimum of once per year, with twice a year being optimal for a home piano. Pianos for advanced students, churches and concert pianists are tuned more often because the needs of the musicians demand a tighter tolerance for tuning and pitch.
Pianos are made of mostly wood, metal and felt. The properties of wood change with the humidity of the seasons and the felt components wear out and change characteristics with time. Over time the pianist may notice a sluggish response, lack of power or keys that stick and play unevenly.
These changes in performance can be corrected with a process called “Regulation”. When the piano technician regulates a piano they adjust the moving components of the piano action including the piano keys to remove lost motion and restore power and touch to the piano.
Frequently, relatively inexpensive adjustments can make an enormous difference in the sensitivity of touch, allowing you to play much more expressively.
Broken keys, stuck keys, buzzes, rattles and rings most often require some level of repair service. I carry enough tools and supplies to repair most broken parts in a single visit for a reasonable price.
Adjustment of the tone of a piano is called voicing. It is accomplished by making careful changes to the shape and density of the hammers. A properly voiced instrument can sound remarkably more beautiful. Voicing is the most difficult skill for a tuner to learn, and it typically takes years to master. I enjoy this task of bringing out the greatest beauty in the sound of an instrument.
