In an ABABACA for the A section would most likely be heard?

In an ABABACA musical form, the A section would most likely be heard at the beginning, followed by alternating B sections, and concluding with a return to the A section. This structure allows for the establishment of a main theme (A), which is then contrasted with different themes (B) before revisiting the original theme, creating a sense of coherence and closure. The repetition of the A section helps reinforce its significance within the overall composition.
