This utility model discloses a musical instrument damping strip, comprising a soft rubber strip with multiple rows of damping posts on its bottom surface. These rows are spaced apart along the length of the rubber strip, and each row includes multiple damping posts spaced apart along the width of the rubber strip. A string-catching groove is formed between adjacent damping posts in each row to accommodate the strings. This musical instrument damping strip, by setting multiple rows and columns of damping posts on the bottom surface of the soft rubber strip, forms a dot-matrix string-catching structure. This dot-matrix string-catching structure eliminates the need for precise alignment and insertion of each string during installation. Users simply place the entire damping strip roughly on the strings, and the strings will naturally fall into the string-catching grooves formed between adjacent damping posts in a row due to their own tension and gravity. This greatly simplifies the installation and disassembly process, saves considerable time, and significantly reduces the difficulty of operation, making it more user-friendly for beginners and children.
