Bluthner are fine sounding German pianos. The action is on the heavy side, the sound is quite beautiful, particularly in the central region of the keyboard. Bluthner produce a small number of upright and grand pianos.
Bluthner is a piano-manufacturing company founded by Julius Bluthner in 1853 in Leipzig Germany. Bluthner’s early success occurred at exhibitions, conservatories and the concert stage. With further invention and innovations lead him to patent a ‘repetition action’, and in 1873 the aliquot scaling patent of grand pianos. This added a fourth, sympathetic (‘aliquot’) string to each trichord group in the treble to enrich the piano’s weakest register by enhancing the overtone spectrum of the instrument. The ALIQUOT string is runs parallel to the normal strings, but is elevated where the hammer strikes so that it is not struck directly, but vibrates in sympathy with the other strings
By 1885 Bluthner they were the largest European piano manufacturer (Bechstein surpassed them in 1905). During World War II the factory was target bombed to ruin but was later rebuilt and opened at the same location. Unique to the great makers, the Bluthner family continues their 5th generation piano building tradition.
Blüthner pianos are known around the world as among the finest. Blüthners’ tone is particularly rich, romantic, colorful, musically balanced and has the longest sustain. Numerous royals, composers, conductors, artists, and performers have owned Bluthner pianos. They include Brahms, Bartok, Debussy, Reger, Wagner, Johann Strauss, Tchaikovsky, Shostakovich, Andrew Lloyd Webber, Wilhelm Kempff, Wilhelm Furtwangler, Yehudi Menuhin, and Marlene Dietrich. Bluthner pianos have also found their place in pop-rock music, as shown in The Beatles‘ Let It Be album, which featured great use of the instrument (most notably, in the hits “Let It Be” and “The Long and Winding Road”). The Bluthner piano was also used in the film “The Sting”.
