1844—Paris, France

The first edition of Hector Berlioz’s orchestration text, Grand traité d’ instrumentation et d’ orchestration medernes, is published. The section on trombone demonstrates detailed knowledge of the instrument; later commentators suspect that he had “inside help” on the section, perhaps from Antoine Dieppo, trombone teacher at the Conservatory and one of the leading trombonists of the age (Macdonald xxix).
