The
contrabass saxophone is the second-lowest-pitched extant member of the
saxophone family proper. It is extremely large (twice the length of tubing of the
baritone saxophone, with a
bore twice as wide, standing 1.9 meters tall, or 6 feet four inches) and heavy (approximately 20 kilograms, or 45 pounds), and is
pitched in the key of E, one
octave below the baritone saxophone.
