Tumburu was one of the sons of the sage Kaśyapa and Ariṣṭā. He belonged to the Gandharva group among the gods of heaven. He was a great musician attached to the court of Indra, the king of gods.
Once he committed a heinous sin and was cursed by Kubera to be born as a rākṣasa (demon). He was born as Virādha. Being killed by Rāma, he regained his original form (vide Rāmāyaṇa, Araṇya-kāṇḍa 4.16-18).
