What type of cadence can be expected in the recapitulation section of sonata form?

In the recapitulation section of sonata form, a perfect cadence is typically expected, resolving previous tensions and reinstating tonal balance. This harmonically stable moment concludes the developmental ideas explored earlier in the piece and re-establishes the original key center. In this section, the themes presented in the exposition are revisited, often in the same order, ensuring a coherent return to the piece's main thematic material.

The recapitulation serves as a culmination of musical ideas, bringing back familiar motives while resolving the harmonic tensions that might have built up during the development section. The resolution of tension is crucial in solidifying the listener's sense of closure and satisfaction, effectively completing the structural journey of the sonata form.

Other options, while related to different musical concepts, do not accurately describe the function of the recapitulation in sonata form. For example, the idea of suspended resolution typically indicates a state of unresolved harmony that is more common in transitional or developmental contexts. Triadic closure does not fully encapsulate the harmonic richness of this structural moment and is somewhat simplistic. Lastly, modal interchange refers to the use of modes other than the primary tonality, which is not the focus in the recapitulative section, where the emphasis is on returning to
