This development reaches a climax during the first chorus at the line "burning down love" (A–G–F–D); the melody progresses through a series of scale degrees that lead to the highest note in the song, the A4 at "burning". In later choruses, Bono sings "blown by the wind" with the same melody, stretching the same note even longer. After the third chorus, the song's outro is played, the instrumentation reverting to the same state as it was in the introduction, with a six-note guitar arpeggio played against sustained synthesiser notes.
