Band instruments are musical tools used in various types of bands, including marching bands, concert bands, and jazz bands. They can be categorized into three main groups: woodwinds, brass, and percussion. Woodwinds include instruments like the flute and clarinet, while brass instruments feature the trumpet and trombone. Percussion instruments consist of drums, tambourines, and cymbals. Each instrument produces sound in different ways. Woodwinds create sound by blowing air through a reed or across an opening, while brass instruments use lip vibrations in a mouthpiece. Percussion instruments generate sound by being struck, shaken, or scraped. Together, these instruments create a rich variety of music.
