This is a homemade violin mute. It reduces the sound during practice. 【Features】 Not only does it provide a clear muting effect audibly, 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 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 just placed on the bridge, it can fall off, and 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 issues, such as instruments that couldn't be attached if I made them the largest size to achieve muting, or a slight reduction in the muting 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, place the side with the sticker towards 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 fit if you have a standard 4/4 violin bridge height, but it may not be possible to attach it to fractional violins. If the height to the E string is insufficient, please consider the separate product, Ottavo. Please forgive any minor scratches from the manufacturing process. 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 falling and damaging the instrument, or the anxiety of not being able to see the contact point between the strings and the bow!
