 In the more complex sonata expositions there can be brief modulations to fairly remote keys, followed by reassertion of the tonic.For example, Mozart's String Quintet in C, K. 515, visits C minor and D major as chromaticism within the C-major first subject group, before finally moving to D major, the dominant of the dominant major (G major), preparing the second subject group in the dominant.Many works by Schubert and later composers utilized even further harmonic convolutions.
