A chorus is the song's big idea, said simply and repeated. It's usually the title.

  1. Find one short line that sums the song up. Say it out loud until it sounds like you'd say it.
  2. Sing it higher than the verse — a lift in the melody is what makes a chorus feel like a chorus.
  3. Repeat it. Twice in a row, or at the start and end of the chorus.
  4. Keep the chords simple; let the melody do the work.
