This is a homemade violin mute. It reduces the sound during practice. 【Features】 Not only does it provide a noticeable muting effect, but the effect is also confirmed numerically by spectrum analysis. In the 1000-6000Hz range, which is the source of noise harmonics, attenuation of 5-10dB is achieved, 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 only placed on the bridge, it can fall off, or cause problems if you put it in the case while attached. ・It leaves marks or rubber stains on the bridge. ・It's heavy. I made this to overcome these issues. The Quarto, which I am selling separately, could not be attached to some instruments because the parts were made larger to achieve muting. However, this time, the parts have been made smaller and have clearance up to the E string. By bringing the parts as close to the strings as possible when attaching them to the instrument, a muting effect similar to that of the larger Quarto is achieved. 【How to Attach】 Attach the two parts so that 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. Finally, raising the parts as high as possible without touching the E string will increase the muting effect. 【Please Note】 The height of this product (from the center of the bridge to the E string) is approximately 21mm, so it should fit if you have a standard 4/4 violin bridge height. Some people have said they could use it on a 1/4 violin, but I cannot guarantee it. In rare cases, even with a 4/4 violin, the height to the E string may not be sufficient due to the shape of the instrument, so please check before ordering. Size: Approximately 42 x 21 x 5 mm Please forgive any minor manufacturing scratches. It may break if subjected to strong impact. 【From Customer Reviews】 ・This is amazing!! ・Unlike metal mutes, the sound is reduced relatively as is, 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 point of contact between the strings and the bow!
