The piano key is the foundation, the lever upon which all other motion depends. Keys are made from natural materials, wood and felt. As such, these parts wear when subject to many years of constant playing. The point at which the lever pivots, both top and bottom, is subjected to wear. This wear can introduce key wobble, which translates to lost power and precision. This becomes very noticeable to the player, as keys become inconsistent throughout the range of the keyboard.
By rebuilding the pivot points and refelting the key bushings we can restore consistency to the key as it travels through its motion. In addition, they keys pivot upon felts which wear and compact over time. This causes the keys to become unlevel – both in the up and down position. This inconsistency can make it difficult to play difficult pieces accurately and diminishes from the joyful experience of practicing piano.
