This is a homemade violin mute. It can reduce the sound during practice. 【Features】 Not only does it provide a clear muting effect audibly, but the effect is also confirmed numerically by spectrum analysis. In the 1000-6000Hz range, which is the harmonic component that causes noise, it attenuates by 5-10dB, meaning the sound is less than half as loud. I always use this when practicing, but 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 contact point between the bow and the 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 be dropped, or it can cause problems if you put it in the case while attached. ・It leaves marks and 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 the muting effect. 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 muting effect similar to the larger Quarto. 【How to Attach】 Attach the two parts so that they sandwich the bridge. It is fixed with strong magnets, so when attaching it to the bridge, slide the small 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 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 possible to attach it 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. If you drop it on a hard floor or subject it to a strong impact, the internal magnets may 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 dropping and damaging the instrument, or the anxiety of not being able to see the contact point between the strings and the bow!
