Tuning a piano involves many small adjustments to string tension for each string. Rather than simply matching the pitch of strings to a standard set of pitches, the tuner listens to the inharmonicity that is inherent in each individual acoustic piano. The piano tuner assesses the interaction among notes, and a slight variation is applied from the theoretical standard to make each piano sound the best for that particular instrument.


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
or  Pre-Purchase 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") to avoid obtaining an instrument with issues that are difficult to detect or costly to repair.

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 highly recommended for quality instruments.
