In your song, you can repeat words, phrases, notes, and chords. The most commonly used and effective types of repetition are choruses, verses, bridges, pre-choruses, post-choruses, hooks, and motifs. Choruses typically contain the title and the main hook and are repeated after each verse. Verses usually tell the story or set the scene with different lyrics but the same melody and harmony. Bridges provide contrast or a twist near the end of the song and are not repeated. Pre-choruses and post-choruses are usually repeated with the same lyrics and melody but may have different harmonies or rhythms. Hooks are catchy or memorable parts that stick in listeners' minds; they can be words, phrases, melodies, riffs, or sounds. Motifs are short musical or lyrical ideas that recur to create coherence, variation, or development.
