c. 1795—Paris, France

Trombonist André Braun publishes Gamme et Méthode pour let Trombones, the first complete modern method book written specifically for trombone. It also contains the first description of a tenor trombone in B-flat with seven chromatic positions (see below image; public domain). It specifically states that the alto trombone is in E-flat, the tenor and bass in B-flat. An influential method book–it informs several later methods, including Fröhlich and Nemetz–the method book also provides an alto trombone position chart clearly showing an instrument in E-flat (see Alto Trombone History Timeline). Editions of the method are subsequently published in German and Italian (Weiner, Braun; Weiner, Braun Revisited; Dudgeon 194).
