strophic:
Strophic form (also called “verse-repeating” or chorus form) is the term applied to songs in which all verses or stanzas of the text are sung to the same music.[1] The opposite of strophic form, with new music written for every stanza, is called through-composed.
The term is derived from the Greek word στροφή, strophē, meaning “turn”. It is the simplest and most durable of musical forms, extending a piece of music by repetition of a single formal section. This may be analyzed as “A A A…”. This additive method is the musical analogue of repeated stanzas in poetry or lyrics and, in fact, where the text repeats the same rhyme scheme from one stanza to the next the song’s structure also often uses either the same or very similar material from one stanza to the next.
