Brass music is a genre that primarily features instruments made of brass, such as trumpets, trombones, and tubas. These instruments produce sound when the player buzzes their lips into a mouthpiece, creating vibrations that resonate through the instrument's tubing. Brass music can be found in various settings, including orchestras, marching bands, and jazz ensembles. The rich, powerful sound of brass instruments often adds depth and brightness to musical compositions. Brass music is known for its versatility, as it can convey a wide range of emotions, from joyful and celebratory to somber and reflective. Many famous composers, like Gustav Mahler and Dmitri Shostakovich, have incorporated brass sections into their works.
