A wooden tuned nut/bolt dumroo is an hourglass-shaped drum with tunable features. Instead of traditional string tension, it uses nuts and bolts to adjust pitch precisely, enhancing sound control. This modern adaptation of the classical dumroo is popular in both folk and classical music for producing stable, rhythmic beats.
The classical folk dumroo is a small, hourglass-shaped drum commonly used in Indian folk music and spiritual rituals. Played by twisting it between the palms, it produces rhythmic beats as two knotted strings strike its surface. This percussion instrument is closely associated with Hindu deity Lord Shiva, symbolizing cosmic sound.
