What is a song structure called that features repeated music for verses and choruses?

The correct answer is strophic. This type of song structure is characterized by having the same music repeated for each verse, making it a highly repetitive and straightforward format. It typically allows the lyrics to change while maintaining a consistent musical background, which is particularly effective for storytelling or conveying a particular mood throughout the song. Strophic forms are common in many genres of music, especially folk and pop, where familiarity and catchiness are key elements.

In contrast, the other types of song structures do not fit this description. Binary, which consists of two distinct sections, does not allow for the repetition of verses with the same music. Through-composed refers to a structure where the music continuously evolves without repeating sections, creating a more dynamic and less predictable flow. Verse-chorus structures do involve repeated music for the chorus, but they typically feature different music for verses rather than consistent repetition across all sections, distinguishing them from the pure strophic form.
