Tourte Round Viola mute
The Tourte Round viola mute, made of rubber, is a popular viola mute which is widely used. The mute stays on the viola when not in use and is then easily slipped on to the bridge when it is required. When engaged, the mute sits across the G and D strings, muting the bridge vibrations. The rubber of the mute is secure to use on your viola and will not damage the instrument or the strings in any way.
