This paper describes the combination of two software systems for work with music corpora in electronic formats. A set of algorithms has been developed in CPN View (a class library for representing music scores) that deals with music score processing. These facilitate access to the ever-increasing collections of music corpora [1]. The Sonic Browser (a browser that uses sonic spatialization for navigating music or sound databases) has been developed to the proof-of-concept and prototype implementation stage. In previous work it has been demonstrated that with the Sonic Browser it is up to 28% faster for users to find a particular melody in a set of melodies, compared to visual browsing [2].
