In sonata form, which section presents the melodic and harmonic themes?

• A. Development
• B. Recapitulation
• C. Coda
• D. Exposition

Answer: (D)

In sonata form, the section that presents the melodic and harmonic themes is where the main tunes and their key relationships are introduced. This part sets up the principal material: a first theme in the home key and a contrasting second theme in a different key, establishing the tonal plan and the melodic ideas that will be developed. The subsequent development then plays with those themes, while the recapitulation returns them in the home key, and a coda may conclude. So the exposition is the stage where the core melodies and their harmonic contexts are first heard.
