Bass clarinets in other keys, peculiarly C and A, also exist, but are very rare against this to the standard A clarinet, which is particularly common in classical music. Bass clarinets continually function in orchestras, wind ensembles/live functionality bands, from time
to time in marching bands, and play an occasional solo role in contemporary music and jazz in certain. Most modern bass clarinets are immediately bodied, with a small upturned silver coloured metal bell and curved metal neck. Early examples varied suit, some having a doubled body making them look corresponding to bassoons. The bass clarinet within reason heavy and is supported either with a neck strap or an adjustable peg linked to its body. While Adolphe Sax imitated its upturned metal bell in his design
of the bigger saxophones, the 2 units are virtually quite a few.
