The Franz Strauss Fantasie is a delightful work for horn and piano.  It begins with an introduction before moving into the presentation of the theme.  There are five subsequent variations, including a Russian rondo.  The first two variations, the Russian rondo, and the final variation present technical challenges which include rapid sixteenth-note passages and challenging articulations.  The Andante is in a 9/8 meter with rich harmony created in part by the eighth notes in the piano accompaniment.  Even with its rigorous technical passages, the piece allows for some rubato in the variations to add diversity to repetitions.  When performing this piece with all repeats, be advised that it can be quite taxing.
