Hancock first heard the work-in-progress in West Hollywood at his home studio, a former guest house in back of his main residence. Hancock determined that the song needed a melody line. Hancock, Laswell and Beinhorn composed one on the spot by humming out loud to each other. Then Hancock recorded his ideas on three different synthesizers, performing on them one at a time. When Hancock suggested performing some vocoder vocal scat, Laswell and Beinhorn said they could instead sample lyrics from a hit song, specifically the line "Rock it, don't stop it" from "Planet Rock", which was at that time a hit for Afrika Bambaataa and the Soul Sonic Force. This lyric sample gave the song the title of "Rockit".
