Uma visão dimensional sobre uma gama tripla: diálogos e reflexões.

Abstract

This dissertation analyzes the harmonic processes used in an electroacoustic composition for triple flute and tape called "Uma visão dimensional de uma gama tripla". The tape of this piece consists of sounds produced by several types of ethnic flutes, wind controller and applications for smartphones. The musical events of the tape are based on mesoamerican scales used in music for marimbas from the Guanacaste (Costa Rica) region, as discussed and detailed by Acevedo (1986). The Triple Flute performed on this piece is a modern version of the Tenenexpan Triple Flute (Veracruz, Mexico), as published by Boiles and Lafayette in a journal of the University of Veracruz in 1965. The harmonic processes and extended techniques used in the piece “Uma visão dimensional de uma gama tripla” are compared with five other pieces of the contemporary repertoire for recorder: Fragmente (Shinohara, 1968), Music for a bird (Martin Linde, 1968), Gesten (Klaus Hashagen, 1966), East Wind (Barry Truax, 1981), and Kage (Roderik de Man, 2000). Fragment and Music for a Bird were composed for solo recorder Gesten, East Wind and Kage are mixed electroacoustic compositions. The cultural references included in the piece "Uma visão dimensional de uma gama tripla" are also analyzed. They correspond to objects found in archeological sites inCentral America, to features of the Mesoamerican architecture, geometric drawings and figures, elements of nature and animals of the regions mentioned, and also musical instruments that are common to pre-Columbian civilizations (Maya and Inca). The use of different types of fingerprints in the execution of the triple flute, the use of extended techniques, the use of sound samples of instruments that do not necessarily follow the same temperament and the processing of the sounds that make up the electroacoustic part show special attention to timbral issues. The overall result of the work corresponds to an amplification of the sound pick that would be obtained with the solo instrument through the exploration of the musical possibilities of the triple flute (chord execution, note overlays and extended techniques) in the context of mixed electroacoustic music. This allowed him to explore relationships and dialogues between the triple flute and a wide range of sonorities of the tape..
