NOTE. Nārada is Lord Brahmā’s son and we learn from Śrīmad-Bhāgavatam 5.25.8 that he is accompanied by Tumburu:

ya eṣa evam anuśruto dhyāyamāno mumukṣūṇām anādi-kāla-karma-vāsanā-grathitam avidyāmayaṁ hṛdaya-granthiṁ sattva-rajas-tamomayam antar-hṛdayaṁ gata āśu nirbhinatti tasyānubhāvān bhagavān svāyambhuvo nāradaḥ saha tumburuṇā sabhāyāṁ brahmaṇaḥ saṁślokayām āsa.

“If persons who are very serious about being liberated from material life hear the glories of Anantadeva from the mouth of a spiritual master in the chain of disciplic succession, and if they always meditate upon Saṅkarṣaṇa, the Lord enters the cores of their hearts, vanquishes all the dirty contamination of the material modes of nature, and cuts to pieces the hard knot within the heart, which has been tied tightly since time immemorial by the desire to dominate material nature through fruitive activities. Nārada Muni, the son of Lord Brahmā, always glorifies Anantadeva in his father’s assembly. There he sings blissful verses of his own composition, accompanied by his stringed instrument [or a celestial singer] known as Tumburu.”

Here is an excerpt from Śrīla Prabhupāda’s purport to this verse: “None of these descriptions of Lord Anantadeva are imaginary. They are all transcendentally blissful and full of actual knowledge. However, unless one hears them directly from a bona fide spiritual master in the line of disciplic succession, one cannot understand them. This knowledge is delivered to Nārada by Lord Brahmā, and the great saint Nārada, along with his companion, Tumburu, distributes it all over the universe.”¹
