Johann Albrechtsberger’s Concerto in F Major was written for trombone and arranged for horn by Edmond Leloir.  Although it is from the same period as the Mozart concerti, it is considerably more difficult.  Its technical challenges include rapid sixteenth-note runs, lip trills, and cadenzas.  In addition to these technical challenges, endurance is also an important consideration to make before programming this work.  The majority of the notes fall in the upper-middle range of the horn; this, in conjunction with the length of the work, may cause fatigue in even the most seasoned player.  This challenging piece is a nice alternative to the Mozart and Haydn concerti.
