Most folk and popular songs are strophic in form, including the twelve bar blues, all of which may be in simple verse or simple verse-chorus form. The "verse-chorus-verse" (verse-chorus form) of most popular music songs may be interpreted as parts of a larger strophic verse-refrain form. In addition, many songs from the classical music tradition are in strophic form, from the 14th century French rondeau of the ars nova, to the 17th century French air de cour, to the 19th century German lieder; indeed strophic form has been one of the most durable of all musical forms, probably because it is intuitively most obvious to have similar music accompanying repeated stanzas of verse.
