The work composed for a chamber music ensemble of rare setting (10 trombones + 2 bass trombones) shows a cyclic layout which is born out by the order of the bagatelles and their movement-like arrangement (Moderato festivo, Scherzando, Sostenuto cantabile, Allegro giocoso, Lento lugubre, Valse moderato, Molto festivo). The sonorous proportions and dynamics relationships are given by the instrumentation itself which facilitates rendering. The Seven Bagatelles develop, above all, the ability to instil character into one's playing.
