Peroração e invenção: análise das codas e codetas, nos movimentos em forma sonata, nas 18 Sonatas para piano de Wolfgang Amadeus Mozart (1756-1791)

Abstract

This paper presents an analytical study of the codas and codettas in sonata-form movements from the 18 solo piano sonatas by Wolfgang Amadeus Mozart. The research investigates how these final sections relate to the rest of the composition, identifying thematic material either reused from the exposition or developed within the codas. Drawing on concepts from musical rhetoric and the galant schemata, the study explores the discursive roles of codas—such as peroratio, confirmatio, and confutatio—within sonata form. Among the 25 movements analyzed, 56% exhibited thematic reuse, highlighting Mozart’s creative and coherent use of codas. This work contributes to a deeper understanding of the structural and rhetorical functions of codas in sonata form and encourages further theoretical exploration.
