We present a system for visuo-auditory substitution that takes as input a depth map, and produces as output a corresponding melody. A real-time apparatus based on the Kinect R ©, a computer and a headphone, is developed within our team. Earlier experiment with the system shows that, when equipped, a sighted person temporary deprived from vision can therefore move in an unknown indoor environmen...

In this work we present an application developed in Derive 6 to compose counterpoints for a given melody (“cantus firmus”). The result is non deterministic, so different counterpoints can be generated for a fixed melody, all of them obeying classical rules of counterpoint. It is also possible that the counterpoint could not be generated, in this case, backtracking techniques have been implement...

The similarity neighborhood is a paradigmatic model investigating similar melodies of equal length depending on the number of appearances of them within a given piece. In the present paper, we propose some extensions to the similarity neighborhood model to identify also the subsequence relationships between melodies of different length. These relations are considered in two directions called th...

We have explored methods for music information retrieval for polyphonic music stored in the MIDI format. These methods use a query, expressed as a series of notes that are intended to represent a melody or theme, to identify similar pieces. Our work has shown that a three-phase architecture is appropriate for this task, in which the first phase is melody extraction, the second is standardisatio...

This chapter describes a music analysis system based on a generative theory of tonal music (GTTM). Musical theory provides methodologies for analyzing and transcribing musical knowledge, experiences, and skills from a musician's way of thinking. Our concern is whether the concepts necessary for music analysis are sufficiently externalized in musical theory. Given its ability to formalize musica...

Obtaining accurate melodic contours from polyphonic music is essential to several music-informationretrieval (MIR) applications and is also useful from a musicological perspective. The presence of tabla and tanpura accompaniment in north Indian classical vocal performances, however, degrades the performance of common pitch detection algorithms (PDAs) that are known to provide accurate results w...
