Types of the Expanded Sonata Form in 19th Century: The “Expanded Type-1 Sonata” and “Type-1 Sonata-Rondo” from Schubert to Dvořák

This research falls into the field of ‘music theory and analysis’ and intends to examine the evolution of particular types of ‘expanded sonata form’ of 19th century through analytical approach.
The ‘expansion’ (an extra inserted section), and the ‘retransition’ (a passage that prepares the recurrence of the primary theme) are significant formal features of the particular types. Thus, the key concepts to be considered regard mostly the function, the characteristics, and the surrounding material of the given features.

The repertory to be examined includes movements of non-programmatic works of 19th-century music for various ensembles (solo, chamber ensemble, and orchestra), which follow the particular sonata types.

The detailed examination of the particular repertory, concerning important formal procedures of the specified expanded formats, aims to answer questions about their function, the frequency they occur, their significance, and the evolution they underwent from 18th to 19th century.
As is well known, during the last decade, a 19th-century sonata theory is under discussion by many important scholars. In this respect, the study also aims to make a contribution to this recently developed and continuing discussion.
