What does 32 bar song form mean?

The 32-bar song form is a common structure in popular music, particularly in jazz and musical theater. It typically consists of four sections, each eight bars long, often arranged as AABA or ABAB. In the AABA format, the A sections present the main theme or melody, while the B section, known as the "bridge," provides contrast before returning to the final A section. This form allows for both repetition and variation, creating a satisfying musical experience.
