The Evolution of Chopin’s Sonata Forms

This study examines the evolving use of sonata form by Chopin, with specific focus on the ways that formal innovations in his early sonatas (opp. 4 and 8) and piano concertos (opp. 11 and 21) anticipate formal patterns in his late piano sonatas (Nos. 2 and 3) and the Cello Sonata; in particular, I excavate Chopin’s application of the second theme group (S) as a primary form-defining unit. In doing so, I investigate additional sonata forms by Chopin and Schubert, introduce a new formal function called “resetting of the formal compass” (RFC), and reconsider a recent debate between Hepokoski/Darcy and Wingfield, providing evidence for the resurgence of early Classical conventions in the heart of the Romantic era.
