. "The C soprano saxophone is a member of the saxophone family. It closely resembles the more common B\u266D soprano saxophone but is pitched a tone higher. Unlike other saxophones (exception: the C melody saxophone), it is not a transposing instrument. The C soprano has a very similar range to the oboe.In the early 20th century, the C soprano was marketed to those who wished to perform oboe parts in military band, vaudeville arrangements, or church hymnals."@en . . . .
