ABSTRACT
Stella is a representation system for the description of persistent, parameterized score information in Common Music (Taube, 1991). It provides a flexible, open ended representation scheme for musical material, and a composition editor to facilitate the creation and modification of parameterized data and larger compositional structures such as gestures, phrases, and sections. Stella implements a powerful referencing and query facility for the examination of parameterized event data. This is critical to the control of complex timbral information, which typically involves not only the interplay between many different parameters of a given event, but their evolution over multiple events as well. Stella is implemented in Common Lisp and CLOS (Steele, 1990), and runs on most standard workstations. A graphic interface for the editor is planned for the SGI Iris Indigo.
