This is a homemade violin mute. It reduces the sound during practice. 【Features】 Not only does it provide a clear muting effect audibly, but the effect is also confirmed numerically through spectrum analysis. In the 1000-6000Hz range, which is the harmonic component causing noise, there is a 5-10dB attenuation, 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 products that are placed on the bridge have a high muting effect, 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. ・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 made had parts that were too large to attach to some instruments because I aimed for greater sound reduction. This time, I 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 muting effect close to that of the larger Quarto. 【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 shocking the bridge. Finally, raise the parts as high as possible, without touching the E string, to increase the muting 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 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. 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 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!
