Which of the following is a common form used in popular music?

The verse-chorus form is a staple in popular music because it provides a clear and engaging structure that resonates well with listeners. This form typically alternates between verses, which tell a story or convey a message, and a memorable chorus that emphasizes the main theme or hook of the song. The repetition of the chorus creates familiarity, making the song more catchy and enjoyable for audiences.

In contrast, AAB form, while also used in some contexts, is less common in contemporary popular music because it can limit the emotional and dynamic range that a verse-chorus structure allows. Sonata form, typically found in classical music, involves more complex development sections and doesn't align with the straightforward, accessible style prevalent in popular genres. Lastly, ostinato refers to a repeated musical phrase or rhythm that may be present in some popular music, but it is not a structural form like the verse-chorus layout. Overall, the verse-chorus form stands out due to its effectiveness in creating engaging, memorable songs that connect with listeners.
