The contrabass sarrusophone sounds two octaves and a major sixth (E♭) or three octaves and a second (B♭) lower than written; the contrabass in C is written in bass clef and sounds an octave lower.[1]
The contrabass sarrusophone is the deepest of the family of sarrusophones, built in three sizes pitched in E♭, C or B♭. It was made in the 19th and early 20th centuries, primarily in France by its inventor and Parisian instrument maker Pierre-Louis Gautrot [fr] and his successor Couesnon & Co. [fr], and Evette & Schaeffer. It was also made in Italy by Milan manufacturers Romeo Orsi and Rampone & Cazzani, and in the United States by C. G. Conn, who built instruments in E♭ for US military bands.[1] Romeo Orsi and the German instrument maker Benedikt Eppelsheim make individual contrabass sarrusophones on request.[2][3]
Tone
The EE♭ sarrusophone has the tone of a reedy contrabass saxophone, while the CC sarrusophone sounds much like the contrabassoon. The BB♭ contrabass sarrusophone is the lowest of the sarrusophones, and was the lowest-pitched wind instrument until the invention of the EEE♭ octocontra-alto and the BBB♭ octocontrabass clarinets, and the BB♭ subcontrabass tubax. Contrabass sarrusophones come in two bore widths: big pipes, which sound mellower and softer, but are still reedy; and small pipes, which are extremely reedy.[4]
The contrabass sarrusophone is sometimes confused with the reed contrabass, to which it bears a superficial resemblance.
Reed
Contrabass sarrusophones take rather large reeds; they are larger than contrabassoon reeds. This leads to most people making their own reeds (as is the practice of most oboe and bassoon players). Contrabass sarrusophone reeds are still manufactured by Vandoren. Sarrusophones are traditionally played with a double reed, but single reed mouthpieces have also been used. These mouthpieces are similar in size to soprano or alto saxophone mouthpieces.
Size
Contrabass sarrusophones are comparatively light for contrabass instruments, weighing only about as much as a baritone saxophone, and being approximately four feet tall, about the same height as a bass saxophone. This makes them more convenient to hold, play and transport.
