RESUMO

The aim of this research was to propose a transference of the indeterminacy issue to the musical morphology field. By evaluating musical works classified as indeterminated in respect of their openess to varied interpretations, we realized that the definition of a musical work in the terms of flexibility or strictness highly depends on how its morphological conformation processes was taken, considering not only the relation, more or less direct, between the music notation and the sound result, but all the choices made by the authors and/or performers, understanding them as essencial parts of the morphological definition for any proposal. The musical work evolves when adapting to external irritations, acquiring compatible forms with the context in which it is executed, independently on how it was previously proposed. When we identify the musical work as essencialy flexible - when it is opened to all kind of interpretations, not considering ideal situations - we enphatize, as a morphological subject analysis, the invariacy strategies that aloud that a specific musical result can make sense even if its first proposition was vage: this notion aloud us to understand the musical result as a product of more or less disciplinated readings of composition proposals in which the objects would have a better chance to reappear in each performance, once the invariancy strategies are strong enough. A relevant aspect of the invariancy strategies comes out with the performance direction job and counts with the support of intersubjective relations of power and the mediation and influency of the musical context, therefore, the invariancy strategies act beyond the notation paradigm. We considered those characteristics and researched the subjective relations that corroborate for the musical work to acquire stable formats, inspite of its obvius openess. Statments about the notion of the collaboration between performers and composers and about the function of hearing and memory as factors of morphological drift, were also discussed in this research
