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 sit on the bridge have high sound-dampening effects, but they have drawbacks such as: ・The point of contact between the bow and strings is not visible when attached. ・The fundamental tone you want to hear during practice is not audible. ・Being placed only on the bridge, it can fall off, or cause problems if left on when putting the instrument in its case. ・It can leave marks or rubber stains on the bridge. ・It's heavy. I made this to overcome these issues. Previous versions I've made had parts that were too large for some instruments to be attached, but 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 mute. 【How to Attach】 Attach the two parts so they sandwich the bridge. They are secured with strong magnets, so when attaching them to the bridge, slide the smaller part from the side to avoid impacting the bridge. Finally, move the parts up as close as possible to the E string without touching it 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 reported using 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 be insufficient due to the instrument's shape, so please check before ordering. Size: Approximately 42 x 21 x 5 mm. Please excuse any minor manufacturing scratches. It may break if subjected to strong impacts. 【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 off and damaging the instrument, or the anxiety of not being able to see the contact point between the strings and the bow!
