What closes a musical piece written in the sonata form?

A musical piece written in sonata form typically concludes with a recapitulation, where the main themes from the exposition are restated in the tonic key. This is often followed by a coda, which serves to wrap up the piece and provide a sense of closure. The coda may include variations of the main themes or new material that reinforces the finality of the piece. Together, these elements create a satisfying resolution to the musical journey.
