i-Berlioz: Interactive Computer-Aided Orchestration with Temporal Control

Abstract

This paper introduces the beta version of i-Berlioz, an interactive CAO system that generates orchestrations from verbal timbre descriptors. This system relies on machine learning models for timbre classification and generative orchestration, and methods and tools to write and execute interactive scenarios. The text details the two main parts of i-Berlioz: its generative and exploratory engines, illustrated with an example of i-Berlioz operational processes. Such a system would ultimately aid the composition of musical form based on timbre.
