Abstract: The present invention (ring mute) is a device comprised of a sound absorbent foam urethane ring with an incision encircling the inner section of the ring with an adhesive strip encircling the outer section of the ring to protect the foam ring from damage. The ring mute is designed to fit onto and around the rim of the bell of a brass musical instrument. The rim of the bell fits into the incision located in the inner section of the foam ring. The purpose of the ring mute is to dampen the sound of a brass musical instrument.

Abstract: The ring mute is a mute made of sound absorbent material which is attached onto and around the rim of the bell of a brass musical instrument instead of inside the bell of the brass musical instrument. The ring mute attachment method creates no apparent air blow restriction or pitch change. This is due to the bell hole of the brass musical instrument not being blocked. The ring mute, as with all mutes increases musical expressivity. The position and construction creates a smooth, rounded, smoky, musical expression for brass musical instruments.
