Piano tuning involves very small adjustments to the tension of each string. The technician does not simply match the strings to a set of pitches. There is an inherent inharmonicity that is different in each acoustic piano. Your tuner assesses this, via listening to the interaction among notes, and a slight variation is applied from the theoretical standard.

Tunings are recommended every 6 months in most locations.

Pitch Raise

A pitch-raise brings a piano, that has not been tuned for an extended time, up (or down) to concert pitch (A = 440). This adds proper tension to each string. Following the pitch raise, the instrument can be fine tuned.

Sticky Keys

Customers often use the phrase "Sticky Keys" to indicate that some keys either repond/reset slowly or don't play at all. This can be caused by a number of issues including restricted key movement, hammer alignment, sticky or broken flanges, bridle straps and regulation.


Adjusting each key mechanism for the best "feel and response". This involves adjusting parameters for each note including proper key travel, hammer travel, let-off distance, backchecks, dampers, and repetition lever.


Voicing is also referred to as tone regulation. It is the art of adjusting the tone quality for the desired amount of brilliance or mellowness that is uniform across the keyboard.

General Repair

Repair, replace, or adjust to correct issues impacting the response and playability of the instrument. Cabinet work may include cosmetics, loose legs, squeaks, rattles, and general cleaning of the piano.


Can include both mechanical and cosmetic enhancement to revitalize the instrument with repair and/or replacement of components.

Piano Evaluation

Evaluate the condition of a piano. This is commonly done prior to a purchase or sale to determine the overall condition and may include a list of needed repairs. An evaluation  is highly recommended prior to obtaining a piano (including the "free piano").

Humidity Control

Installation of the Dampp-Chaser system to automatically control the humidity in the piano. This system automatically manages both moisture and dryness issues. This will help to stabilize tuning and environmental issues with the many wooden parts. This system will extend the life of the instrument.
