Nothing beats the full sound of a brass instrument. Its tone is created by the vibration of a player's lips as he or she blows into the "resonator" or mouthpiece. Most brass instruments are made from brass with a coat of lacquer over it. Some more professional models can be silver or nickel plated over brass. The determining factor for the classification of "brass" though is how the sound is produced. For example, the brassy-looking saxophone is a woodwind instrument.
"Valved" brass instruments use a set of 3 to 5 valves that opens and closes the tubing of the instrument and is operated by the player's fingers. This includes the trumpet, cornet, French horn, baritone horn, and tuba. Slide brass instruments, such as the trombone, use a slide to change the length of tubing and therefore change the pitch.
