The Yamaha Silent Brass system has revolutionized the way trumpet players practice. The Silent Brass system functions both as a mute and as an amplification system that only the player can hear. You don't have to sacrifice airflow or tone to practice in peace, and you can say goodbye to annoying your family and neighbors.
