Definition & Meaning of "cornet"

What is a "cornet"?

A cornet is a brass instrument similar to a trumpet but with a more compact, coiled shape and a slightly softer tone. It has a smaller bell and uses three valves to change the pitch. The cornet is played by blowing air through a small mouthpiece and is known for its warm, mellow sound. It is commonly used in brass bands, concert bands, and various other musical ensembles. The cornet’s smooth, rounded tone makes it well-suited for both melodic and harmonic roles in a variety of musical genres.
