brass instruments

Brass instruments are wind instruments made from metal that produce sound when the player buzzes their lips into a mouthpiece. The sound's pitch is controlled by changing the length of the instrument's air column, which is achieved through valves or sliding mechanisms, and by adjusting lip tension. Common examples include trumpets, trombones, and tubas. They are used in various musical genres for their powerful, resonant tones and require skillful breath control and lip coordination to produce different notes. Brass instruments often serve as both melodic and harmonic elements within ensembles and bands.
