Alto clarinet

The alto clarinet is a woodwind instrument of the clarinet family. It is a transposing instrument pitched in the key of E♭, though instruments in F have been made. In size it lies between the soprano clarinet and the bass clarinet. It bears a greater resemblance to the bass clarinet in that it typically has a straight body (made of grenadilla or other wood, hard rubber, or plastic), but a curved neck and bell made of metal.
