It closely resembles the more common B♭ soprano saxophone but is pitched a whole step higher.

As with C melody saxophones, American production of C sopranos commenced circa 1919 and ended around 1929.

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.

In the early 2010s, the New Zealand–based company Aquilasax contracted a factory in China to produce C sopranos, with modern keywork but a bore copied from C.G.

These received a very mildly positive response from players and technicians who encountered them,[1] but demand was low and only a small number was produced.
