Bass saxophone

The bass saxophone is one of the largest members of the saxophone family—larger than the more commonly encountered baritone saxophone. It was the first type of saxophone presented to the public, when Adolphe Sax presented a bass saxophone in C at an exhibition in Brussels in 1841. The modern bass saxophone is a transposing instrument pitched in B♭, an octave below the tenor saxophone. The bass saxophone is not commonly used in any music, but it is heard on some 1920s jazz recordings; in free jazz; and in the saxophone choir or "large ensemble" tradition.
