Which musical structure is characterized by sectional repetition in reverse order and overall symmetry?

The musical structure characterized by sectional repetition in reverse order and overall symmetry is arch form. This form features sections that mirror each other, creating a symmetrical structure. In arch form, the first section is often followed by a contrasting middle section, and then the music returns to the first section or something resembling it, providing a clear sense of balance and unity.

This type of construction is prevalent in various genres of music, particularly in the works of composers who prioritize structural coherence and emotional symmetry. The arch form is particularly effective in creating a sense of journey or exploration, where the initial material returns in a way that feels satisfying and resolved.

In contrast, the other options do not embody this specific characteristic of symmetrical and reversed sectional repetition. Fanfare typically refers to a short ceremonial tune or flourish, usually for brass instruments. Senza misura indicates a free, unmeasured tempo, rather than a structured form. The verse-chorus form is commonly used in popular music, but it does not emphasize the overall symmetry and reverse order that define arch form.
