Concertino in E minor, for horn and orchestra, J.188, op. 45

The Concertino for Horn and Orchestra in E minor, J. 188 (Op. 45), was composed in 1806 for the Karlsruhe player Dautrevaux, and revised for the Munich virtuoso Rauch in 1815 (completed on 31 August) by Carl Maria von Weber (Warrack 1976, p. 167). It is an extremely taxing work, whether played on the natural horn for which it was written, or on the modern valve horn. The soloist is accompanied by a small orchestra. It requires, among other feats, that the player produce what is in effect a four-note chord using the interplay between humming and the sound from the instrument, a technique known as multiphonics.
