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. In the 1000-6000Hz range, which is the harmonic component that causes noise, there is a 5-10dB attenuation, 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 mutes and similar products that are placed on the bridge have a high sound-dampening 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 be dropped, or putting it in the case while attached can cause problems. ・It can leave marks or rubber stains on the bridge. ・It's heavy. I made this to overcome these issues. Previously, the mutes I've made had conflicting challenges, such as not being able to attach them to some instruments if I made them the largest size to achieve sound dampening, or a slight reduction in sound-dampening effect if I made them smaller. This time, I combined large and small parts to solve these problems. I also made the parts separate for easy attachment and removal. 【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. Basically, the side with the sticker should face the fingerboard. If the parts happen to touch the strings, you can almost always fix it by reversing the front and back. 【Important Notes】 This product is approximately 21mm high (from the center of the bridge to the E string) with the small part and approximately 26mm with the large part. It should fit if you have a standard 4/4 violin bridge height, 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 be insufficient due to the instrument's shape, so please check before ordering. Please forgive any minor manufacturing scratches. Dropping it on a hard floor or giving it a strong impact may cause the internal magnets to break. 【From Customer Reviews】 ・This is amazing!! ・Unlike metal mutes, the sound is reduced pretty much as is, which is great. ・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!
