In addition to the four works listed above, there are two incomplete concerto movements, K. 370b and the Concert Rondo, K. 371, both from 1781 and both in E-flat major, and a 91-bar fragment of the first movement for a concerto in E major (K. 494a), written in 1785 or 1786.[2]
Discography
Given the duration of the concertos (no more than 20 minutes each) it is quite common to find these horn concertos on the same CD, or in boxed sets of Mozart's concertos for wind instruments or even all his concertos. The Naxos Records CD Complete Works for Horn & Orchestra includes, besides the concertos, three rondos for horn and orchestra completed by musicologists.
