Abstract

In this paper we present a flexible composition system called LOCO. It is user extendible, modular, orthogonal, and contains good mechanisms for naming and abstraction. Although the system has the power of a general programming language, it is easy to use for non-programmers. The system took the form of several microworlds in a Logo environment. A microworld is a small set of powerful tools that constitute a more less complete or closed system. The tools were implemented as program generators. Several music composition worlds were made each expressing a different viewpoint or accent in computer music composition.
