The main purpose of this dissertation is to offer classical guitarists an additional analytical technique for interpreting and performing the music of Johann Sebastian Bach. While this mode of analysis can be successfully applied to any of the instrumental works by Bach frequently transcribed and performed by guitarists, I have chosen for this study my recent transcription of the Partita in A minor for solo flute traverso, BWV 1013. With a continuo-based, harmonic realization of the Partita, I contribute to the existing guitar repertoire by offering a new transcription of this work, while demonstrating how historical concepts of rhetorical structure and aesthetics found in relevant primary source material can inspire a new approach to analysis, transcription, and performance practice. In this way, my investigations create additional perspectives for classical guitarists regarding the analysis and performance of this work, while complementing traditional harmonic analysis and subject labeling. Although it is my hope that this new transcription of the Partita will serve as an important contribution to the existing literature, the main purpose of this dissertation resides in the musico-rhetorical analytical technique and its implications on performance practice for classical guitarists.
