Aliquot stringing and The Golden Tone
Blüthner pianos have a unique tone and one of the main reasons is the use of Aliquot stringing.
Julius Blüthner invented the Aliquot stringing system as early as 1873 which combines the use of an additional fourth string for each note of the top three octaves of the piano. The innovative fourth string is positioned slightly higher than the other three strings and isn't actually struck by the hammers Whenever the hammer strikes the three conventional strings or other harmonically related strings, the aliquot string vibrates sympathetically.
The effect is to broaden the depth of vibrations across the soundboard and throughout the instrument, creating a warm and more complex tone. Famous author and piano technician Larry Fine describes the Blüthner tone as refined and delicate. We call it The Golden Tone.
Only the finest timber, carefully selected from all over the world and seasoned over many years, is used as the basis for the outstanding quality of our instruments. A gentle drying and maturing process ensures that the sensitive membranes of the cells within the wood remain intact so that vibrations can move across the instrument without a significant loss of energy. Using traditional craftsmanship, the solid rim is assembled as part of a robust, tension-free design that enhances resonance and forms the firm foundation for the world-famous Blüthner soundboard.
More than 4,500 parts that form a Blüthner piano are built and assembled with superior accuracy. The combined experience of generations of piano makers underlies the special knowledge used to create the famous Blüthner sound. The soundboard, the heart of every Blüthner instrument, is crafted by the most skilled artisans, leaving nothing to chance by maintaining the highest standards of quality control.
Our design to our hammers contributes substantially to the unique Blüthner sound. Crafted from the finest Australian felt, arched over a core of walnut wood, and individually voiced to perfection, the Blüthner hammers stimulate the purest vibrations of the strings. These distinctive hammers are connected to shanks made from white beech, carefully hand-fitted using traditional natural glue.
Striving for perfection down to the smallest detail is our passion. Like gold plating the instrument, the voicing of the Blüthner instrument is performed by the best among the best to bring to life the soul of each instrument, presenting the perfection and beauty of the sound to its owner. Our passion for excellence, our fascination with detail, and our drive for continuous improvement have shaped our philosophy. To create pieces of the finest art that outlive many generations is our challenge.
