Understanding your piano.

At least twice a year for a home piano, per manufacturer and Piano Technicians Guild guidance, usually spring and fall. A new piano needs three to four tunings in its first year while it settles; performance instruments are tuned far more often.

Humidity. The wooden soundboard swells in humid air and raises string tension and pitch, then shrinks and drops the pitch as the air dries. Those seasonal swings move every piano, played or not.

A corrective overpull done before fine tuning when a piano has fallen well below standard pitch. Because restoring tension flexes the frame and pulls tuned notes flat, the technician overpulls so the instrument lands at pitch once it settles.

Tuning sets the pitch of the strings; voicing shapes the tone of the hammers, brighter or more mellow, and evens it note to note. A piano can be in tune and still sound harsh or uneven, which is a voicing matter, not a tuning one.

Yes. Firming the hammer felt builds brightness and projection; needling it softens a harsh tone toward warmth. Voicing moves an instrument along that spectrum to suit the player and the room.

Almost always the action needs regulation. Over time the felt and cloth in the mechanism compress, and the many adjustments behind each key drift out of specification, so some notes feel heavy, others light, and fast repetition suffers.

A check and light regulation every few years suits most home pianos, with a fuller regulation as the instrument ages. New and heavily played pianos need attention sooner.

It is worth restoring when the finished value, in quality, money, or sentiment, exceeds the cost. Fine instruments such as Steinway and Mason & Hamlin were built to be rebuilt and reward it; inexpensive, mass-produced pianos usually are not economical to rebuild.

Potentially the soundboard, pinblock, all strings, the action (with Renner parts), bridges, key surfaces, and cabinet finish, followed by complete regulation and voicing. The scope is set after inspection.

A stable one. Keep a piano away from heating vents, radiators, fireplaces, exterior doors, and direct sun, and aim for steady humidity around the low-to-mid 40 percent range. Stability matters more than any single number.

Where room humidity cannot be reliably controlled, a Dampp-Chaser Piano Life Saver System installed inside the piano holds the air next to the soundboard steady, improving tuning stability and protecting the structure. We assess the room and recommend it when the environment warrants.
