song structure (popular music)

The structures or musical forms of songs in popular music are typically sectional forms, such as strophic form. Other common forms include thirty-two-bar form, verse-chorus form, and twelve bar blues. Popular music songs are rarely through-composed.The verse and chorus are considered primary, while the introduction and coda or ending may or may not be used in different performances and are not considered essential to the identity of most songs. A bridge is slightly more important. The verse and chorus are usually repeated throughout a song though the bridge, intro, and outro are usually only used once.
