Here's a new video (from our forthcoming Setup online course), explaining all about Mutes and Practice Mutes.
There are two main types of mute you can use with the violin – standard mutes, and practice mutes. They dampen the vibrations of the bridge and the strings, which softens the sound.
We use standard types of mute to change the tone of the sound for *musical* reasons, but practice mutes are much thicker and heavier than other mutes, and are usually made out of metal or rubber. They're great for practising when you don't want to disturb other people with your violin practice!
