This paper presents two novel user interfaces for investigating the pattern content in monophonic jazz solos and exemplifies how these interfaces could be used for research on jazz improvisation. In jazz improvisation, patterns are of particular interest for the analysis of improvisation styles, the oral transmission of musical language, the practice of improvisation, and the psychology of creative processes. The ongoing project "Dig That Lick" is devoted to addressing these questions with the help of a large database of jazz solo transcriptions generated by automated melody extraction algorithms. To expose these transcriptions to jazz researchers, two prototypes of user interfaces were designed that work currently with the 456 manually transcribed jazz solos of the Weimar Jazz Database. The first one is a Shiny application that allows exploring a set of 653 of the most common patterns by eminent players. The second one is a web interface for a general two-staged pattern search in the Weimar Jazz Database featuring regular expressions. These applications aim on the one hand at an expert audience of jazz researchers to facilitate generating and testing hypotheses about patterns in jazz improvisation, and on the other hand at a wider audience of jazz teachers, students, and fans. |
