Introduction, Andante, et Allegro is a thru-composed work by Gioacchino Rossini for horn and piano.  This piece is significantly more accessible to younger players than his Prelude, Theme, and Variations, because it does not require as much flexibility or as advanced of a technique.  In spite of its simplicity, there are some technical challenges: lip trills, large leaps, and ability to perform embellishments.  It is a pleasant work, requiring good rhythm and dynamic contrast from the performer.  It is also accessible to an advanced high school student.  This piece, often overlooked for Rossini’s Prelude, Theme, and Variations, is truly a treasure that makes an excellent opening recital piece.
