The objective of this paper is to offer a contribution to the study of performance and, more specifically, development of performance analysis methodologies and techniques through a brief comparative analysis of the tempo deviations in four interpretations of Du schönes Bächlein, a composition by Hans Werner Henze (1926–2012), as performed by four different guitarists. Graphs and representations are developed to demonstrate the tempo deviations in each of the selected recordings, followed by analysis of the respective collected information.
