One of the seven svara (swara, musical note) is Ṛṣabha (Rishabha) svara or dhvani . In Mahābhārata (Mahabharata) it is said that the grave and tuned sound, like the sound of clouds that emanated from the Pāñcajanya Śaṇkha (Panchajanya Sankha; the Conch named Panchajanya) was similar to that of Ṛṣabhadhvani.
pāñcajanyasya nirghoṣamārṣabheṇaiva pūritam
śrutvā subhairabhaṁ nādamupayāyā javena mām.
The alternative name of Pāñcajanya Śaṇkha is Ārṣabha, since it creates the Ṛṣabhadhvani (Rishabhadhvani).
