Inserindo o trompete em Mi bemol e em Ré de 4 pistons na Banda da Polícia Militar do Distrito Federal: estudo de caso.

Abstract

This study aims to present the considerations that supported the use of the 4 valves E-flat and D trumpet and the data collected from the experiences with the use of this instrument in the Band of the Military Police of the Federal District. Having as main references the studies of Wilfredo Cardoso, David Hickman and Heinz Schwebel, an experimental research on the contextualization and feasibility of insertion of the practice of four valves E-flat and D trumpet and a subsequent verification of losses and gains compared with the trumpet in B flat in the military repertoire. We used as variables the articulations, the level of dynamics, the contrasts of the dynamics, the equipment used, the muscular fatigue and the change of range. During the experiments we could see that the use of trumpet in E-flat and D of four valves in the military repertoire, preferably in the first voice, is a totally viable option, although unpopular due to developments that go beyond technical issues, and that can bring advantages to the performance of the military trumpeter.
