The chorus is the part of a song that repeats multiple times throughout the song. Choruses use the same lyrics and melody each time they appear in the song. Choruses are catchy. They’re the part of the song you’re most likely to sing along to.
Verses tell the “story” of the song. Although sometimes Songwriters repeat a verse for artistic effect near the end of the song, most often, verse lyrics are different each time while the melodies stay the same. Verses are the prelude to the chorus.
