What are facts about tanpura?

The tanpura is a traditional Indian string instrument primarily used in Hindustani Classical Music as a drone. It typically has four or five strings and is played by plucking while the instrument is held upright. Unlike other string instruments, the tanpura does not play melodies but provides a harmonic foundation that supports vocalists and instrumentalists. Its resonant sound is achieved through a hollow wooden body, often made from seasoned wood, which enhances the tonal quality.
