Why is a mute used on violin to muffle the sound stop or vibrate sounds?

Mutes are not specifically used on violins to muffle the sound, stop or vibrate sounds. Depending on the playing technique or effect intended, violin players may use a mute to alter the sound. Different types of mutes can create various tonal changes, such as subduing the brightness or mellowing the tone. When used correctly, a mute doesn't stop or completely muffle the sound; instead, it creates a muted effect on the violin's overall tone.
