The violin mute is divided into two types: wooden and metal, and three types: plastic. It is an accessory installed on the qin horse, with its gap placed on both sides of the qin horse during use, which can suppress the vibration of the qin horse, weaken the body of the qin, and change the tone. It is often used in beginners of the violin or in special effects of playing music. Removing the mute will not affect the vibration of the original qin and horse.

In general, it is not necessary to use a mute. For novice violinists, it may be because they are afraid of affecting others when practicing the violin again. In this case, it can be used temporarily and not for a long time. Long term use may have an impact on your hearing. Also, when playing music, special effects need to be used to express different emotions.
