A contribution to the study of the dynamisation of the recapitulation in Ludwig van Beethoven's piano sonatas

This paper analyses the first movements of Ludwig van Beethoven's piano sonatas to examine approaches to the recapitulation, with particular focus on certain specific and innovative solutions. The analysis reveals that while some recapitulations rely on a straightforward restatement of the exposition's material, accompanied by necessary tonal adjustments, others feature subtle modifications typical of this sonata-form section, as well as instances that radically transform the traditional concept. A notable form of transformation is the dynamisation of the recapitulation, where, in some cases, a reconsideration of the recapitulation's customary function can be observed, significantly impacting the overall dramaturgy of the sonata form. Different concepts of the recapitulation are presented according to the degree of alteration, ranging from simpler, conventional changes to new, original approaches (notably in Op. 31 No. 2, Op. 53, and Op. 106). The most basic forms of dynamisation involve increased acoustic dynamics, rhythmic revitalisation, and particularly the introduction of accompanying voices through so-called rhythmic acceleration. Structurally, frequent fusions of adjacent sections are observed, especially between the first theme and the bridge, though expansions of the second theme also occur. Tonal interventions also serve as important means of dynamising the recapitulation's musical flow, including excursions into the subdominant area, mediant relations, unconventional treatments of the first theme and bridge within the recapitulation, and highly developed harmonic schemes in the second theme. To achieve dynamisation, Beethoven sometimes radically disrupts the tonal 'reconciliation of themes' - as notably exemplified in the recapitulation of Sonata Op. 78, where clear new developmental processes emerge. These techniques demonstrate a profound engagement with the sonata form's core and anticipate future compositional directions.
