This paper presents our framework for music information retrieval and visualization (CoMIRVA). We focus on the functions for visualizing similarities between music artists or songs and describe some approaches we have already implemented. In particular, we present a novel three-dimensional visualization technique based on a geographic model, the very simple “Circled Bars” visualization which could be used for example for mobile devices, and a graphbased visualization approach for prototypical artists.
