A mute is an object that is fitted to the end of a brass instrument to change the instrument’s sound and tone. Mutes can be made from many materials but aluminum, brass, and copper are common. A mute works by changing the shape of the instrument and absorbing its acoustic vibrations. This causes the instrument to produce a sharp, damp sound. Mutes are often used in jazz music but sometimes they are called for in other compositions as well.
