Jacques Castérède's works for brass are monumental and demand extreme agility from the performers. Many brass players are familiar with the Sonata for Trombone, but Castérède's trumpet repertoire has not been as thoroughly considered. Due to the lack of scholarly works and recordings of Jacques Castérède trumpet repertoire, a study is necessary to aid its performance. The study is based on performance analysis and interviews with the composer. The first chapter provides information on the composer's life. The second and third chapters are performance analysis of Brêves Rencontres and Concertino for Trumpet and Trombone. These two chapters also discuss rehearsal technique and sound concept. The performance guide takes place in chapter 4. This chapter gives specific indications on articulation, range and mute choice.
