COLLABORATIVE PROCESS IN ARENGARÔA (2017) A PERFORMANCE FOR AMPLIFIED PLASTICS, PERCUSSION AND COMPUTER

This article discusses practical-interpretative aspects during the process of collaboration between the author (composer-interpreter) and the composer Caio Pierangeli, which resulted in the work Arengarôa (2017). Our work was inspired by the construction of the performance of Microplástic PET (2012) by Matthew Burtner, whose process is also described in this paper.The objective of this article is to describe the techniques developed by the interpreter and applied in plastic materials in percussive performance with technological interaction.The methodology consisted in the collection of discarded plastic objects, followed by an experimentation workshop comprised of three moments: instrument construction; technical-instrumental development; and the creation of computational programming. As a preliminary result of this research, we highlight: the Tororó, an instrument made from plastics objects; the creation of techniques applied to plastics; the choice of the resulting sonorities; plastics amplification strategies; the creation of sound processing and the interaction of electronics in real time. From this, we describe the collaborative process between composer and interpreter in the creation of a computational programming created to expand the sonorities of plastics. This process culminated in the composition of Arengarôa (2017), a work for Toroó, percussion and computer.
