Linear models for the organization of musical works, such as block-forms, Fugue and Sonata form, have a long and well-established history in Western Culture. Since the 1950s computer technology has increasingly been brought to bear upon the role of coordinating sound structures. The centralised nature of the computer's control of sound sources has permitted a compositional shift from predetermined linear structures to ones that unfold in real-time where the work's content is not tethered to the time and order of their appearance. This shift is mirrored in other mediums and their equivalent non-linear offshoots, notably literature (hypertext) and multimedia (hypermedia). This paper will survey a range of non-linear structural models and propose potential applications of these models for real-time interactive musical works.
