Song structure
Song structure is the arrangement and sequence of sections within a song, such as verses, choruses, bridges, and introductions.
Verse (music): A song section with recurring music and changing lyrics that develops the song’s narrative or ideas. Verses commonly alternate with choruses and supply changing material between their repetitions.
Repetition (music): The recurrence of musical material, including melodies, rhythms, harmonies, or entire sections. Repeating choruses and other sections makes a song’s form recognizable.
Thirty-two-bar form: A song form, common in popular music and jazz standards, built around a 32-bar pattern, often divided into four eight-bar sections. Its compact repeated pattern offers a clear alternative to verse–chorus organization.
Musical arrangement: The selection and distribution of musical parts, instruments, and textures in a performance or recording. Arrangement concerns how parts sound; structure concerns how sections are ordered.
Chorus (song): A recurring song section that usually carries its central lyrical and musical hook. Its repeated return often anchors the song’s overall form.
Musical form: The organization of musical ideas into larger units and patterns over time. Song structure is a specific kind of musical form organized around song sections.
AABA form: A musical form with two similar A sections, a contrasting B section, and a return to A. This pattern organizes many songs through contrast and return rather than a recurring chorus.
Songwriting: The creation of songs through lyrics, melodies, harmonies, and other musical ideas. Song structure is one set of decisions within the broader practice of songwriting.
Bridge (music): A contrasting section that provides a change in harmony, melody, or perspective within a song. A bridge can interrupt verse–chorus repetition before the final return.
Refrain: A recurring line or phrase in a song, often repeated at the end of verses or within a chorus. A refrain can provide a recurring hook without constituting a separate chorus.
