A saxonette is a soprano clarinet in C, A, or B♭ that has both a curved barrel and an upturned bell, both usually made of metal. It has the approximate overall shape of a saxophone, but unlike that instrument it has a cylindrical bore and overblows by a twelfth. The instrument is also known as the 'Claribel' and 'Clariphon'. First Produced by Buescher Band Instrument Company between 1918 and 1921 under the name Clariphone. A "Sax-Clarinet" appeared in the Couesnon catalogue of 1934. Couesnon instruments are amongst the most common instruments around today.
