The contrabass saxophone is the second-lowest-pitched extant member of the saxophone family proper. It is pitched in E♭ one octave below the baritone saxophone, which requires twice the length of tubing and bore width. This renders a very large and heavy instrument, standing approximately 2 metres (6 ft 7 in) tall and weighing around 20 kilograms (44 lb). Despite this, it was used in marching bands in the early 20th century.
