Considered a descendant of Mridangam, the Pakhawaj is mainly used to accompany the Dhrupad style of Hindustani classical music. Pakhawaj produces a rich, low, and mellow tone. This instrument has a barrel-shaped body with two side openings covered by goatskin. The two heads are of different sizes; the bigger one produces the bass, and the smaller one produces the treble. On the face that produces the bass, freshly made wheat flour batter is applied to produce an enhanced, low-pitch sound.
