The "Horn Concertos" of Mozart are staples of the solo horn repertoire, and this well-known edition contains all of them, along with the Concert Rondo for Horn.
A difficult solo with difficult accompaniment, only for your best soloist. But a spectacular solo worth every bit of the work put into the preparation.
