“From the early part of the century until the late 1920’s, Mason & Hamlin was Steinway’s most serious competitor for the concert stage, a high-quality instrument advertised as the ‘costliest piano in the world.’ However Mason & Hamlin lacked the stability afforded by continuity of ownership and family association enjoyed by Steinway” --Encyclopedia of the Piano, edited by Robert Palmieri, Garland Publishing, Inc., New York 1996

This piano is in VERY GOOD original condition with beautiful sound. The action has been checked and regulated. Original bench included. New M&H pianos in this class sell for 32,000. We can ship to any of the 48 states.
An acoustic piano produces sound by a felt hammer striking a string causing the string to vibrate. The string is stretched over a “bridge” which transmits the vibrations to the soundboard. The soundboard is the amplifier of an acoustic piano. Sound is made of pressure waves in the air. As the soundboard vibrates it causes these pressure waves in the air. The larger the soundboard, the more contact it will have with the air and the more sound waves it will transmit. Thus Mason & Hamlin pianos sound like pianos much longer than they are.
Mason & Hamlin uses white spruce for its soundboard. White spruce has a higher strength to weight ratio than the sitka spruce used by some other manufacturers of high quality pianos. Because mass of white spruce is lower, less energy is required to make the soundboard vibrate.

Mason & Hamlin is the only piano in the world with a tension resonator to preserve sound board crown: Why is this important?
The soundboard in fine pianos is made of spruce, a wood with a very high strength to weight ratio. The low mass allows string vibrations to be easily transferred to it. The soundboard is installed in the piano in an arched fashion (“crown”) in tension like a drumhead to maximize the transmission of the sound waves. The soundboard is rigidly mounted to the rim (structural framework) of the piano.
The strings on an acoustic piano are stretched to a very high tension, as much as 40,000 pounds. This tension exerts a downward force on the soundboard of about 1,000 pounds. This force tries to reduce the arch and push the soundboard edges and the rim out. With time this pressure can cause the soundboard to flatten and lose tension thereby decreasing the power and duration of the sound.
All Mason & Hamlin pianos have a steel turnbuckle attached to the rim (“the tension resonator”) to prevent the rim from ever expanding, permanently preserving the soundboard crown and thereby the power, dynamic range and sustain of the instrument. We at European Pianocraft have rebuilt dozens of Mason & Hamlin pianos that are 70 to 80 years old and the soundboards always have crown. This is not always true of other fine instruments.
The Mason & Hamlin grand piano rim is made of hard rock maple and is much more massive that comparable size pianos. Why is this important?
As the strings vibrations are transferred to the soundboard, the whole soundboard vibrates out to the edges where it is attached to the rim. If the rim is soft or lacks density, the vibrations are absorbed by the rim and the soundboard loses energy and the piano loses power and dynamic range.
Both Steinway (New York) and Mason & Hamlin use hard rock maple rims. When the sound producing energy reaches the rim, the greater the mass and stiffness of the rim, the more resistant it is to vibrating in sympathy with the soundboard. If the rim is very stiff, the sound vibrations are instantly and efficiently reflected to the soundboard preserving the sound energy. The thickness of the Mason & Hamlin rims increases its stiffness, mass and its ability to reflect soundboard energy.
Compare the rim thickness of the Mason & Hamlin models to the New York Steinway models.

All Mason & Hamlin pianos have a full perimeter harps. Mason & Hamlin pianos are the only pianos manufactured today in the world to have full perimeter plates. Why is this important?
The pitch of an individual piano string is determined by its length, its tension and its and mass. Because the piano is a wooden instrument, it will expand and contract with changes in temperature and humidity. Even infinitesimal expansion or contraction will cause changes in the speaking length of the strings and cause the instrument to go out of tune. The Mason & Hamlin piano’s full perimeter plate in conjunction with its tension resonator makes it much more rigid that any other piano and therefore less susceptible to expansion and contraction from environmental factors. This results in unsurpassed tuning stability.
All Mason & Hamlin pianos have Kluge keys and Renner actions. Why is this important?
The keyboard and the action are the piano player’s interface with the instrument. A poor action will impede the player’s ability to express him or herself and to interpret the composer’s intention. Bosendorfer, Bluthner, Bechstein, Fazioli, Mason & Hamlin, and Steinway (Hamburg) use Renner actions and Kluge keys.
Mason & Hamlin grand pianos feature individual aliquots for each treble unison that can be tuned to the pitch of the unison. Why is this important?
Duplex or aliquot scaling of a piano permits the “non-speaking” portion (from the back bridge pin to the hitch pin on the plate) of the string to vibrate in sympathy with the speaking portion of the string (the portion struck by the hammer). Theodore Steinway first used the duplex scale in 1872 to impart more color to the fundamental tone by the addition of harmonic partial tones. Steinway uses aliquot bars where each unison is preset within the register (sections of the treble portion of the piano which are divided by the structural members of the harp). If casting imperfections in the harp or minute variations in bridge pin locations cause variations in the speaking lengths of the strings within the register, the duplex scaling will not work or worse it can impart harsh tones and false beats. Mason & Hamlin developed individually tunable aliquots to overcome this potential problem. Only Mason & Hamlin and Fazioli pianos have individually tunable aliquots.
