saxhorn
any of a family of brass wind instruments patented by the Belgian instrument-maker Antoine-Joseph Sax, known as Adolphe Sax, in Paris in 1845. Saxhorns, one of many 19th-century developments from the valved bugle, provided military bands with a homogeneous series of valved brass in place of the miscellany of valved instruments that had come into use since 1825 (such as flugelhorns, or valved bugles; cornets; euphoniums; and others)
