Novel Music Segmentation Interface and the Jazz Tune Collection

Abstract

In this paper we present MOSSA, an easy-to-use interface for mobile devices, developed to annotate the segment structure of music. Moreover, we present the jazz tune collection (JTC), a database of 125 Jazz melodies annotated using MOSSA, and developed specifically for benchmarking of computational models of melody segmentation. Each melody in the JTC has been annotated with segment boundaries by three human listeners, and segment boundary salience by two human listeners. We provide a light analysis of the inter-annotation-agreement of the annotations in the JTC, and also test the likelihood of the annotations been made using ‘gap’ related cues (large pitch intervals or interonset-intervals) and ‘repetition’ related cues (exact/approximate repetition of the beginning or ending of phrases).
