The sonata became a great innovation of the classical period. The parts of sonata include?

The parts of a sonata typically include:

1. Exposition: This is the first section of the sonata, where the main musical ideas are presented. It consists of two contrasting themes or melodies, usually in different keys.

2. Development: In this section, the composer takes the themes from the exposition and develops them further. There may be key changes, variations, and elaborations of the themes, creating tension and building suspense.

3. Recapitulation: This is where the themes from the exposition return, but this time both are presented in the same key. It provides a sense of resolution and stability after the development section.

4. Coda: The coda is a concluding section that follows the recapitulation. It typically provides a final ending to the piece, often with a different musical material or a restatement of the main themes.

In addition to these main sections, sonatas can also include other elements, such as introductions, transitions between sections, and codettas (mini-codas) within the main sections.
