Steingraeber & Söhne 138 T-SFM
The SFM mechanism The SFM mechanism is the result of years of research and testing. The outcome is a piano action that runs just as smoothly and rehearses quickly as a grand piano action. One of the secrets of the SFM mechanism are the magnets. These are placed under the leather of the hammer nut and the pusher. All parts for this are specially manufactured by the famous Renner brand.
Top quality wood
The quality of the wood is of vital importance for a piano maker and Steingraeber & Söhne does not take any risks. It is stored at a carefully controlled and constant humidity of 40%. For soundboards, Steingraeber exclusively uses 'Bergfichte•, slowly grown spruce wood with the annual rings close together, which is at least 250 years old. "The soundboard is not only an amplifier, but also the source of the sound. Therefore, the resonance of the wood must correspond to the register of the piano for which it is used. The solid red and white beech wood used for the combs, after entering the factory it is left to rest for another three years before being processed.
The largest piano in the world
Steingraeber & Söhne has made a name for itself with its model 138 by manufacturing the largest piano in the world. Model 138 with a string length of 128 cm and a soundboard as large as a 180 cm grand piano.
Named the best piano in the world 7 times: In the last ten years, Steingraeber & Söhne pianos have been awarded 'Le Choc' - a prize for the best instrument - 7 times by the French magazine 'Le Monde de la Musique'.
Principles of classical keyboard construction
To achieve optimal results, everything is assembled in the studios at Steingraeber & Söhne, down to millimeters: The soundboard, bridge and cast iron frame are adapted to the soundboard and not the other way around.
The frame is first coated with paint and from the print on the tuning block (which, depending on the model, consists of 20 to 32 layers of beech wood) you can read whether the connection for optimal communication between the different parts is perfect. All this is extremely important because, as they say at Steingraeber: "the energy from the string must be transferred to the soundboard as efficiently as possible; with as little or no loss as possible." That is why even the smallest detail is not forgotten. For example, the pins that hold the strings in place on the bridge are made from exceptionally hard steel by a specialized company. Sticking the comb is also a job that requires special attention and craftsmanship.
At Steingraeber it is still manual work that involves a lot of 'Fingerspitzengefühl'.
Manufacturing process
It's not just about top materials and craftsmanship, time is also an important factor, which according to Steingraeber & Söhne is highly underestimated. At Steingraeber & Söhne, the total production time for a piano takes four months, for a grand piano this is six months.
