This three-movement sonata for horn in F is a standard piece in the horn’s repertoire.  The piece’s high difficulty rating stems not from use of extended techniques or fast, articulated passages, but from the technically demanding rhythms, sustained playing, difficult intervals, and wide leaps.  The most difficult movement rhythmically is the third, because of the mixed meter.  The first movement is the one most often performed by students, because it affords them the opportunity to learn how to play long sustained phrases at a loud dynamic, with a good sound.  A good collaborative pianist is a must for this piece due to the complexity of the piano part.
