In a track-and-hook song, the hook comes as soon as possible. Then the song “vamps”—progresses in three- or four-chord patterns with little or no variation. Because it is repetitive, the vamp requires more hooks: intro, verse, pre-chorus, chorus, and outro hooks. “It’s not enough to have one hook anymore,” Jay Brown explains. “You’ve got to have a hook in the intro, a hook in the pre, a hook in the chorus, and a hook in the bridge, too.” The reason, he went on, is that “people on average give a song seven seconds on the radio before they change the channel, and you got to hook them.”
