Tuning is the adjustment of the tension of all of your piano's 220 (or more) strings to the correct pitch or frequency.


Your piano is designed to sound its best when tuned to A-440 (A above middle C vibrates at 440 cycles per second), the international pitch standard. At this pitch, power and tonal range are optimum and the piano will match the pitch of other instruments.


Keep your piano in tune. Your piano will sound its best when it is tuned regularly and kept in proper playing condition. This ensures that notes played in a musical interval (octaves, chords, etc.) will sound in harmony.

Voicing is the adjustment of a piano's tone or quality of sound. Voicing gives more brilliance or softness to individual notes or entire sections of the scale.


A piano's tone changes with use. As the piano is played, the hammer felt compacts and develops string cuts, causing a harsh uneven tone, robbing the pianist of the ability to produce a sweet sound. Voicing can restore the pleasing tone of your piano.

Piano Voicing Tool

The complex system which causes a hammer to strike a string when you press a key is called the piano's action. It is a marvel of engineering composed largely of wood and wool felt. This mechanism needs to be responsive to every nuance of the pianist's touch - from loud, thunderous chords to soft, delicate passages.


Action regulation is the adjustment of each of its parts to a tolerance of a few thousandths of an inch. Because the wood and felt parts of the action change due to wear and humidity, the action must be serviced occasionally to maintain its responsive qualities.

Rebuilding & Reconditioning

Reconditioning is the process of putting a piano back in good condition by cleaning, repairing, and adjusting for best performance with parts replacement only where necessary. This is most appropriate for a piano with only moderate wear or those of medium value with average performance requirements.


Reconditioning does not involve replacing major components such as the soundboard, bridges, pinblock, and most action parts. This means the performance and life-span of an older piano will not be restored to new. Instead, reconditioning is designed to improve a piano's performance, keeping in mind both costs and benefits.


Rebuilding involves complete disassembly, inspection, and repair as necessary, including replacement of ALL worn, damaged, or deteriorated parts. This piano is then reassembled, tested, and adjusted to the same or similar tolerances as new. COMPLETE REBUILDING includes the entire pianos structure -- including soundboard, bridges, pinblock, and strings -- as well as the action, keyboard, and case refinishing. PARTIAL REBUILDING includes only one or two of these areas, for example rebuilding of the action and structure, but not case refinishing.


Rebuilding restores the piano to original condition or better. Such comprehensive work is usually most practical for high-quality instruments here maximum performance and longevity are required.

Humidity Control

While not eliminating the need for regular piano maintenance, humidity control will allow more stable tunings by reducing the radical pitch changes your piano may experience through the seasons. When your piano stays closer to its correct pitch level of A440 (A-440 cycles per second), your technician does not have to perform a large pitch raising or lowering procedure prior to fine tuning. Thus, a balance of forces is maintained between the strings and the frame of the piano, allowing more accurate and stable tunings to be done.


In addition, a stable environment will help to preserve your piano through the years. Wood parts, glue joints, metal parts and your piano's finish will all last longer if not subjected to excessive humidity swings. Maintaining the correct environment will preserve your piano investment for a lifetime of enjoyment.
