The Chorus is particular type of refrain, usually shorter than the traditional refrain, often bearing repetitive phrases, often designed for chorus (or audience) to sing along. The musical theatre chorus is distinguished from the chorus in pop music. In pop music, the structure is typically verse/chorus, verse/chorus…which is equivalent in musical theatre to verse/refrain, verse/refrain. The chorus in musical theatre is much shorter, and most closely resembles the “na na na na” section of a pop song (like “Hey Jude” or King George’s “ba da da” from “Hamilton”). Musical theatre songs with singalong chorus include: “You’ll Be Back” (Hamilton) and “Schmuel Song” (The Last Five Years).
