Joseph Leutgeb (1732-1811) was probably the most sought-after Horn virtuoso in the classical era. He was traveling from one European capital to another, amazing large audiences with his mastery of the instrument. In the year of 1763 Leutgeb settled in Salzburg, making friends with local composer Leopold Mozart and his seven year old son, Wolfgang. In 1777 he moved to Vienna, and in 1782 he started his musical collaboration with Wolfgang Mozart, now a mature composer. Leutgeb was also known as the subject of Mozart’s joyful practical jokes. It is known that Mozart wrote the solo part of his Fourth Horn concerto using multi-colored ink in order to confuse the poor hornist. In one of the sections of his second Horn concerto he marked the orchestra’s tempo as Allegro, while the horn’s solo part was marked Adagio, mocking the tendency of Horn players to extend long notes and drag the tempo. The horn quintet. KV.407, is the first piece writtenby Mozart specificallyfor Leutgeb. Its original instrumentation is rather unusual: one violin, two violas and one cello accompany the Horn. We will hear today an arrangement in which the string instruments’ parts are arranged for violin and piano. The piece consists of three movements: an opening Allegro in Sonata Form, a lyrical andante (which includes a love duet between the Horn and the violin) and a closing humorous rondo.
