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 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 only sits 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. 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 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 close as possible to the E string without touching it to increase the sound-dampening effect. 【Important Notes】 This product is approximately 21mm high (from the center of the bridge to the E string), so it should fit a standard 4/4 violin bridge, but it may not be attachable to fractional violins. 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. Please forgive any minor scratches from the manufacturing process. Dropping it on a hard floor or subjecting it to strong impacts may cause the internal magnets to break. 【From Customer Reviews】 ・This is amazing!! ・Unlike metal mutes, the sound is reduced quite naturally, which is great. ・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!
