Hatten’s theory of musical gesture : an applied logico-deductive analysis of Mozart’s Flute quartet in D, K.285

Abstract

This study investigates the possibility of applying Hatten’s theory of musical gesture to a formal system of musical analysis. Using historical antecedents and established musicological practice as a guide, a range of musical parameters in a motive length span of music are incorporated into a single gesture. This gesture forms the basic semantic unit upon which an analytical tableau structure is built, and a syntax is developed to allow derivations of new gestures; a large scale structure displaying fractal-like self-similarity is then proposed. The completed system is applied to the analysis of the ‘Adagio’ of Mozart’s Flute Quartet K.285 to test whether it can consistently be implemented and whether it produces falsifiable results while maintaining predictive power. It is found that these requirements are indeed met and that a set of inference rules can be derived suggesting that the proposed system has ample scope for further development.
