Final answer:
In a verse-chorus song structure, the turnaround is a short musical interlude that follows the second chorus, enabling a smooth transition back to the verse or other sections of the song. It's similar in concept to the volta in a sonnet but serves a different function in music.
Step-by-step explanation:
In songs that employ a verse-chorus structure, the turnaround is a brief musical interlude that follows the second chorus. While not as commonly discussed in pop music terminology as verses and choruses, the turnaround serves a vital function, allowing the song to transition smoothly back into another verse or musical section.
The concept of a 'turn' in music is somewhat analogous to its usage in poetry, such as in a sonnet. A sonnet traditionally consists of fourteen lines, featuring a volta or a turn in thought, which signifies a shift in the poem's subject or perspective, usually occurring between the octet (first eight lines) and the sextet (last six lines). However, it's important to note that a musical turnaround and a poetic volta serve different artistic functions and occur in different contexts within their respective art forms.
