Theory as Practice: The role of ornamentation and rhetorical devices as essential expressive elements in the keyboard works of J. S. Bach.

通过分析J·S·巴赫的键盘作品，我将揭示实音符装饰和修辞手法对于巴赫的音乐表达是必不可少的，因为它们增强和传达了巴赫的意义。从一开始作为一种即兴现象，巴赫音乐中的装饰就成为了一种结构性的表达需要。我将识别这些作品中包含的装饰性和修辞性人物，并从符号学的角度解释它们的表达和解释可能性，通过创作关于时代和现代键盘乐器的录音来将我的发现付诸实践，使学者、表演者和观众能够接触到它们。

By analyzing selected keyboard works of J. S. Bach I will reveal that real-note ornamentation and rhetorical figures and devices are essential to Bach's musical expression as they enhance and communicate its meaning. From its beginnings as an improvisatory phenomenon, ornamentation in Bach's music becomes a structural expressive necessity. I will identify the ornamental and rhetorical figures contained within the pieces and explain their expressive and interpretative possibilities in terms of a semiology of 'Affekt', implementing my findings in practice by creating audio recordings on period and modern keyboard instruments to make them accessible to scholars, performers and audiences.
