Cornet

Brass instrument

The cornet (US:) is a brass instrument similar to the trumpet but distinguished from it by its conical bore, more compact shape, and mellower tone. The most common cornet is a transposing instrument in B♭. There is also a soprano cornet in E♭ and cornets in A and C. All are unrelated to the Renaissance and early Baroque cornett.
