The musical arrangement opens with an introduction, where West utters a series of ad-libs and onomatopoeic vocables atop tumbling delayed beats. He then begins rapping his lyrics, which are intertwined with a twinkling piano melody. The track's cascading piano line is accompanied by warped bass and a subtle interjection of acoustic guitar. With a relaxed flow, West raps the song's two verses as well as a pre-chorus which shifts into a delicate refrain delivered by Adam Levine, who sings in a falsetto register. His smooth tenor delivery and gentle cooing punctuate the introspective tone of each verse. Following a bridge, the musical composition enters a coda, where it acquires more instrumentation. This orchestral passage expresses keyboard flourishes, wailing synthesizer, twinkling Chinese bells, whistles and jangling berimbau percussion before the song fades out.
