User:Ovinus/Brass acoustics

Brass acoustics is an area of musical acoustics concerning how the sound of a brass instrument is produced. A player places their lips on the instrument's mouthpiece

A brass player manipulates their lips to play different notes on the instrument, and multiple notes can be played on a single. In most brass instruments, ... explain normal 2nd, 3rd harmonic stuff .... A few, such as the didgeridoo, do not follow such a pattern. The length of the air column helps determine the pitches that can be played. Acoustically, a brass instrument cannot be modeled as a simple closed pipe, which only has resonances at odd harmonics. Factors including the varying diameter of the instrument's air column alter these resonances.

The player's lips vibrate in the mouthpiece of the instrument, introducing puffs of air at regular intervals which maintain a standing wave in the instrument's air column. The sound projects out of the instrument's flared end, or bell.
