In the context of electroacoustic music production, specially in the acousmatic version, the human gesture will not develop its primordial role - the utilized material, in this case, is obtained no longer exclusively by the physical action of an agent who produces it. In this tendency, the musical discourse is constructed by sounds and noises that no longer are obligatorily proceeding from determined musical instrument played by a performer, but created and processed in studio. Based on such premises, this present work has the intent of pointing possibilities of applications of the use of the gesture as a structural principle in the electroacoustic musical creation, through the compositions Trajetórias, Metagestos and Entre Planos. Three gestural approaches are used in the creation process. The first mentioned piece is the acousmatic work Trajetórias, where the use of the electroacoustic gesture is applied in its pure form, without explicit relations with instrumental gestures. Another approach is the also acousmatic piece Metagestos, where the creation of gestures used as material is done based on gestural instrumental models. The third case is the mixed piece for cello and electroacoustic sounds Entre Planos where, inside of the same musical context, the instrumental gestures interact with the electroacoustic gestures. With such compositional experiences, we believe that the use of gestures as structural principle may be a strategy, front to the new sound possibilities that in many times may relate with the lived musical experience of the listener, who may already possesses in his perceptual repertoire a range of sound motions that will be re-interpreted in electroacoustic context, being perhaps possible to provide a certain indirect familiarity with such motions.
