Brass instruments are well known for their strong sounds and their power within a band or orchestra. The cowhorn was the original root of all brass instruments centuries ago. From that humble beginning has come a wide range of brass instruments of all sizes and with a wide range of sounds. Brass bands may be a relatively new invention, but brass instruments and their wooden and bone musical ancestors have been used in war and to announce royalty for centuries. These instruments have a wide range of pitches, and David Munrow demonstrates how they are achieved in this 30-minute video. Find out how these instruments work and how they are used as the backbone of the modern orchestra and marching band.
