Mozart, pianoforte sonata, No.

10, second movement (_Rondeau en polonaise_).

The continuity and unity of this composition is so complete that it is certainly a Rondo-form; the principal theme is a fairly large Three-Part form; the subordinate theme (measure 47-69) is a Two-Part form, the second part corresponding in contents to the second Part of the principal theme; the _recurrence_ of the principal theme is abbreviated to one of its three Parts, and is merged in the coda (last seven measures), which assumes the nature of a mere extension.

Despite all this evidence, there still remains a certain impression of structural independence, which, so to speak, betrays the "seams," and militates somewhat against the spirit of the perfect Rondo-form.
