According to the literature, the concerti for 3 horns were composed between 1800 and 1811. Schneider often made concert tours together with the hornists Boetticher and Marquart. They had big success with these concerti. Further information under the following link Biography.
The mentioned concerti for three horns in E major were kept in the library in Darmstadt (court library) and burnt in 1994 during the war. Fortunately, copies were found in a collection in the USA, which were copied before the war (1913/1914) from the music in Darmstadt. Thus the concerti for three horns are rare exemplars. In the 18th/19th century, concerti for three and four horns were composed frequently, but only a few are kept.
