This is a homemade violin mute. It reduces the sound during practice. 【Features】 Not only does it provide a noticeable sound-dampening effect, but its effectiveness is also confirmed numerically through spectrum analysis. It attenuates the 1000-6000Hz range, which is the source of noise-causing overtones, by 5-10dB, meaning the sound is less than half as loud. I always use this when practicing, and I'm surprised by the loud sound when I occasionally forget to put it on ^^ ARTINO and similar mutes that are placed on the bridge have high sound-dampening effects, but they have drawbacks such as: ・The contact point between the bow and strings is not visible when attached. ・The fundamental tone you want to hear during practice is not audible. ・Since it's only placed on the bridge, it can fall off, or cause problems if you put it in the case while attached. ・It can leave marks or rubber stains on the bridge. ・It's heavy. I made this to overcome those issues. Previously, the mutes I've made couldn't be attached to some instruments because the parts were made large to achieve sound dampening. This time, I've made the parts smaller and allowed for clearance up to the E string. By bringing the parts as close to the strings as possible when attaching them to the instrument, I've achieved a sound-dampening effect similar to the larger Quarto. 【How to Attach】 Attach the two parts as if sandwiching the bridge. It is fixed with strong magnets, so when attaching it to the bridge, slide the smaller part from the side to avoid impacting the bridge. Finally, move the parts up as much as possible without touching the E string to increase the sound-dampening effect. 【Important Notes】 The height of this product (from the center of the bridge to the E string) is approximately 21mm, so it should fit if you have a standard 4/4 violin bridge. Some people have said they could use it on a 1/4 violin, but I cannot guarantee it. In rare cases, even with a 4/4 violin, the height to the E string may not be sufficient due to the instrument's shape, so please check before ordering. Size: Approximately 42 x 21 x 5 mm. Please forgive any minor scratches from the manufacturing process. It may break if subjected to strong impact. 【From Customer Reviews】 ・This is amazing!! ・Unlike metal mutes, the sound is reduced relatively naturally, which is good. ・It's great to be able to practice without worrying about the mute slipping or falling and damaging the instrument, or the anxiety of not being able to see the contact point between the strings and the bow!
