According to Srila Jiva Gosvami, Lord Krishna sang many wonderful melodies and meters, and the gopis accompanied Him, following His lead. Krishna's singing on this occasion is described in the Sri Vishnu Purana:
krishnah sarac-candramasam
kaumudim kumudakaram
jagau gopi-janas tv ekam
krishna-nama punah punah
"Krishna sang the glories of the autumn moon, the moonshine and the lotus-filled river, while the gopis simply sang His name repeatedly."
