C soprano saxophone

The C soprano saxophone is a member of the saxophone family. The instrument was invented in 1846. It closely resembles the more common B♭ soprano saxophone but is pitched a whole step higher. Unlike most other saxophones, it is not a transposing instrument, a quality it shares with the C melody saxophone (also called the C tenor saxophone). The C soprano has an identical range to the oboe.

American production of C sopranos commenced at Buescher in 1915 and generally ended in the late 1920s. The same companies that made C melody instruments manufactured C soprano saxophones, and they were marketed to those who wished to perform oboe parts in military bands, vaudeville arrangements, or church hymnals. C sopranos made by some French manufacturers exist. However, the C sopranos made by some French manufacturers exceedingly rare.
