Two mṛdaṅgas (mridanga; one kind of earthen instrument) named Nanda and Upananda were posted upon in the flagpost of the chariot of Yudhiṣṭhira (Yudhishthita). The two sounded well when the chariot was on the move. In Droṇaparva (Dronaparva)of Mahābhārata (Mahabharata) , Upananda has been mentioned as Upanandaka.
