Practice mutes are devices used by musicians, particularly brass and woodwind players, to reduce the volume of their instruments while practicing. They allow musicians to play without disturbing others, making them ideal for home practice or in shared spaces. These mutes can be made from various materials, including rubber, metal, or plastic, and are designed to fit snugly into the instrument's bell or mouthpiece. Using a practice mute can also help musicians focus on their tone and technique without the distraction of loud sound. While they lower the volume, practice mutes may slightly alter the instrument's sound quality, so players should also practice without them to maintain their overall sound.
