At six minutes and twenty-one seconds, "Whatever" was the longest single the band had released up to that point (it was later surpassed by "Champagne Supernova"). The song follows an AB structure, which differs from Verse-Chorus, as the main hook occurs at the beginning of the song. The song suddenly changes key during the bridge, before returning to the main chord progression of the song, which repeats for a two-and-a-half-minute outro in which, one by one, each instrument cuts out until only the strings are playing. Finally, the song ends with an extended, recorded applause track.
