Unsupervised Learning and Interactive Jazz/Blues Improvisation

We present a new domain for unsupervised learning: automatically customizing the computer to a specific melodic performer by merely listening to them improvise. We also describe BoB, a system that trades customized real-time solos with a specific musician. We develop a probabilistic mixture model, derived from the multinomial distribution, for the clustering and generation of variable sample-si...

Blues for Gary: Design Abstractions for a Jazz Improvisation Assistant

We describe the design and implementation of a tool to help students learn the art of jazz improvisation. The tool integrates elements of database, AI in the form of automatic melody generation, and human interface design. We describe the philosophy of using several coordinated mini-languages to provide user specifications for various aspects of the tool, including melody and chord representati...

Currently used, mass-market systems tend to be very poor with respect to security and reliability, since they routinely contain serious bugs and vulnerabilities. While a redesign of these systems would be a sound long-term solution, an ef...

Computer Analysis of Jazz Chord Sequences : Is Solar a Blues ? in Readings in Music

This chapter investigates the issue of the role of the computer in musical analysis. Starting with a survey of the main approaches in computer analysis, we focus on the particular problem of Jazz chord sequences harmonic analysis. We propose a theory of chord sequence analysis, based on an explicit conceptual hierarchy of analysis objects. We discuss the implementation of the theory and its res...
