Editing Thirty-two-bar form (section)

=== Terminological confusion ===
In early-20th-century terminology, the main 32-bar AABA section, in its entirety, was called the "[[refrain]]" or "chorus". Accordingly, jazz players improvising on the 32-bar sections may still speak today of "blowing for a couple of choruses".<ref>{{cite web |url=https://www.jazzinamerica.org/lessonplan/8/2/203 |title=lessonplan/8/2/203-Musical Elements |author=<!--Not stated--> |date=n.d. |website=www.jazzinamerica.org |publisher=Herbie Hancock Institute of Jazz |access-date=24 January 2024 |quote="In a nutshell, the format of the performance of a jazz tune is: head for one chorus - improvised solos for several choruses - head for one chorus."}}</ref> This is in contrast to the modern usage of the term "chorus", which refers to a repeating musical and lyrical section in [[verse–chorus form]]. Additionally, "verse", "chorus", and "refrain" all have different meanings in modern musical terminology. See the below chart for clarification:
