Discontinuum-continuum: the Theory of Composition by Julio Estrada

The Julio Estrada’s output is still an unexplored area, what creates the opportunity to study the phenomenon called discontinuum-continuum. During the last thirty-six years of his creative activity, Estrada has developed several aspects of the macro-timbre that integrate particular compounds of a composition. In his research, Estrada confronts two different situations in the compositional process: continuous transformation of the sound and chronographical method, using strictly defined recording process in order to receive three-dimensional movements of the sound in the topological order. As a result of existence these two situations, a musical work is impossible to be defined by one technique or musical style. Examination of the theory of composition called discontinuum-continuum allows one to understand a new methodology of musical creation that involves scientific research of the physical phenomenon of sound and introspection of the imagination of the sound.
