The term "Cornett" refers to a brass musical instrument that resembles a trumpet but has a softer, mellower tone. It is typically made of brass and has a conical shape, which contributes to its unique sound. The cornett is played by buzzing the lips into a mouthpiece, similar to other brass instruments, and it is often used in early music ensembles. Historically, the cornett was popular during the Renaissance and Baroque periods, often used in both sacred and secular music. It is sometimes confused with the cornetto, a woodwind instrument, but they are distinct. The cornett has seen a revival in modern performances of early music.
