• śaṅkha — conchshells
  The pāñcajanya class of conch — emblematic of Viṣṇu (Pāñcajanya in Kṛṣṇa's hand) and of victory. Its sound in this verse is the cosmic echo of Govardhana-līlā: the upper region announces what Vraja has performed.
• tumburu - pramukhāḥ — led by Tumburu
  Tumburu — the chief Gandharva, master of celestial music. His leading the song signals the highest tier of svarga-sangīta has been redirected to Kṛṣṇa. Gauḍīyas note: every art reaches its perfection only when offered at His feet.
• deva - pracoditāḥ — played by the demigods
  deva + pracodita (incited, set in motion). The demigods themselves drive the instruments. The verb is a quiet correction: deva-pracoditāḥ — devatās moving in the Lord's direction — is the proper deployment of celestial śakti.
• neduḥ — resounded
  From √nad. The Veda uses the same verb of mantras and conches that announce sacred events. Heaven's nāda has joined Vraja's nāma-saṅkīrtana — one sound, two altitudes.

Conchshells and kettledrums sound; Tumburu and the Gandharva-chiefs sing. The same heavens that supplied the storm now supply the music — and the music is not for Indra; it is for the boy whose finger held up the hill. Heaven's music has changed its dedicatee.
