the great sage Narada Muni.

The seven musical notes—sa, r, ga, ma, pa, dha and ni—are used in musical instruments, but originally they come from the Sama Veda. The great sage Narada vibrates sounds describing the pastimes of the Supreme Lord. By such transcendental vibrations, such as Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, he fixes his mind at the lotus feet of the Lord. Thus he directly perceives Hrsikesa, the master of the senses. After delivering the Haryasvas, Narada Muni continued traveling throughout the planeary systems, his mind always fixed at the lotus feet of the Lord.
