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 and similar mutes that are placed on the bridge have a high sound-dampening effect, 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's only placed on the bridge, it can be dropped, or putting it in the case while attached can cause problems. ・It leaves marks and rubber stains on the bridge. ・It's heavy. I made this to overcome these issues. The ones I've made so far had conflicting challenges, such as instruments that couldn't be attached 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 that they sandwich the bridge. They are fixed with strong magnets, so when attaching them to the bridge, slide the small part from the side to avoid impacting the bridge. Basically, the side with the sticker should face the fingerboard. If the parts come into contact with the strings, you can almost always fix it by reversing the front and back. 【Important Notes】 This product is about 21mm high (from the center of the bridge to the E string) with the small part and about 26mm with the large part, so it should be fine if you have a normal 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, the height to the E string may not be sufficient due to the shape of the instrument, so please check before ordering. Please forgive any minor scratches from manufacturing. If you drop it on a hard floor or give it a strong impact, the internal magnets may break. 【From Customer Reviews】 ・This is amazing!! ・Unlike metal mutes, the sound became smaller as it was, which was good. ・After all, it's good 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!
