Concurrent Real-Time Music in C++

MOOD is a C++-based programming system for algorithmic and interactive music generation. MOOD uses multiple concurrent processes to generate di erent aspects of musical structure (pitches, rhythm, dynamic variation, etc.). It is composed of three layers. Layer one supplies deadline-scheduled lightweight processes and real-time event generation. Layer two allows processes to be collected into hierarchical group structures, with associated \virtual time systems" and nested musical transformations. Layer three provides pitches, scales, notes, rhythm speci cation, and higher-level musical abstractions. MOOD derives several bene ts from C++ features such as inheritance and operator overloading: 1) a simple and versatile syntax for music representation � 2) a clean, layered structure for the internal scheduling mechanisms � 3) easy factorization of the machine-dependent parts (MOOD now runs on Sun 3 and 4 workstations under UNIX, and on the Macintosh).
