Jivari

In Indian classical music, javārī (Hindi: जवारी) refers to the overtone-rich "buzzing" sound characteristic of classical Indian string instruments such as the tanpura, sitar, surbahar, rudra veena and Sarasvati veena. Javari can refer to the acoustic phenomenon itself, or to the meticulously carved bone, ivory or wooden bridges that support the strings on the sounding board and produce this particular effect. Historically, the concept of a Jiwari bridge was being applied to the Mesopotamian lyres 4500 years ago. (see link below). A similar sort of bridge is used on traditional Ethiopian lyres, as well as on the ancient Greek kithara, and the "bray pins" of some early European harps operated on the same principle. A similar sound effect, called sawari, is used on some traditional Japanese instruments as well.
