The bass saxophone is one of the lowest-pitched members of the saxophone family—larger and lower than the more common baritone saxophone. It was likely the first type of saxophone built by Adolphe Sax, as first observed by Berlioz in 1842.^[1] It is a transposing instrument pitched in B♭, an octave below the tenor saxophone and a perfect fourth below the baritone saxophone. A bass saxophone in C, intended for orchestral use, was included in Adolphe Sax's patent, but few known examples were built. The bass saxophone is not a commonly used instrument, but it is heard on some 1920s jazz recordings, in free jazz, in saxophone choirs and sextets, and occasionally in concert bands and rock music.

Music for bass saxophone is written in treble clef, just as for the other saxophones, with the pitches sounding two octaves and a major second lower than written. As with most other members of the saxophone family, the lowest written note is the B♭ below the staff—in the bass's case, sounding as a concert A♭₁ . German wind instrument maker Benedikt Eppelsheim and Brazilian low saxophone maker J'Elle Stainer have both made bass saxophones with an additional key to produce low (written) A. This is similar to the low A key on the baritone saxophone, and produces a concert G₁ (~ 49 Hz). Most basses made before the 1980s were keyed to high Eb, but most more recent models are keyed to high F#.
