How did the concerto differ from earlier types of concertos?

The concerto differed from earlier types of concertos in several ways:

1. Increased prominence of the solo instrument: In earlier concertos, the solo instrument was often treated as just one part of the overall ensemble. In the concerto, however, the solo instrument took on a much more prominent and virtuosic role, often engaging in dialogue and competition with the orchestra.

2. Three-movement structure: The concerto typically had a three-movement structure, consisting of a fast opening movement, a slow and lyrical middle movement, and a lively final movement. This structure became the standard for concertos during the Classical era.

3. Emphasis on contrast and drama: The concerto emphasized contrast and drama between the soloist and the orchestra, with the soloist often showcasing technical skill and musical prowess. This created a sense of tension and excitement throughout the piece.

4. Clear delineation between soloist and orchestra: In earlier concertos, the distinction between the soloist and the orchestra was often blurred, with both playing together in a more collaborative manner. In the concerto, there was a clear delineation between the soloist and the orchestra, with the soloist standing out as the focal point of the music.

5. Development of the cadenza: The concerto introduced the cadenza, a solo section within the piece where the soloist could showcase their technical skill and creativity. Cadenzas became an integral part of concertos, allowing soloists to personalize and embellish the music.

Overall, the concerto represented a significant evolution in the form and structure of concertos, placing greater emphasis on the soloist, contrast, and drama, and establishing a standard three-movement structure that would influence concertos for centuries to come.
