Written by Brian Wilson and Mike Love, the song is in the vein of the band's previous surf ballads and features Four Freshmen-inspired harmonies.
"[1] It is a ballad in a similar vein to Wilson's 1963 song "Surfer Girl", but more musically complex[2] and sexualized.
[4] Biographer Peter Ames Carlin writes of an "erotic" quality in the song, reflected "both in the lyrics and in the voices themselves, which fall, climb, and tangle languidly through a series of augmented chords with a loving intimacy that communicates all the passion simmering beneath the words.
[1] Biographer Jon Stebbins praised Dennis's line "the sun in her hair / the warmth of the air" as "[o]ne of the most perfect uses of [his] sexy voice", and the closing block harmonies as "one of the group's finest moments".
[9] In addition, he notes that the song "shows off Brian's incredible vocal-arranging skill, with complex group blends and multiple key changes".
