Which of the following accurately describes the organization of the Horn Concerto's third movement?

The organization of the Horn Concerto's third movement is accurately described by the choice that highlights the presence of a main theme that recurs multiple times. This characteristic is often a hallmark of classical concertos, where the presence of a primary theme allows for development and variation throughout the movement. The recurrence of the main theme provides structure and cohesion, enabling the composer to explore different musical passages and variations while keeping the listener engaged through familiarity with the theme.

This practice of repeating a main theme with variations can lead to an exciting interplay between the soloist and the orchestra, resulting in a dynamic and engaging musical experience. The recurring theme may be presented in different ways, allowing for a display of virtuosity and expression from the soloist, while also showcasing orchestral accompaniment that complements the solo part.

In contrast, options that suggest a single theme with no variations or patterns of multiple contrasting themes without repetition do not capture the typical structure found in such concertos. Additionally, the notion of the movement featuring only the soloist without orchestral backing fails to acknowledge the typical dialogue and collaboration between the solo instrument and the orchestra that is fundamental to concerto form.
