The bass clarinet, usually pitched in B{{music|b}}, has a tube twice as long as that of a standard clarinet; because of its unwieldy length, it doubles back on itself with the bell pointing upwards at the bottom. The clarinet family even includes an enormous contrabass clarinet, pitched in either of two keys: B{{music|b}} or E{{music|b}}. This instrument is most often found in large orchestras, wind ensembles, or concert bands. | The bass clarinet, usually pitched in B{{music|b}}, has a tube twice as long as that of a standard clarinet; because of its unwieldy length, it doubles back on itself with the bell pointing upwards at the bottom.
