From Wikipedia, the free encyclopedia
Joseph Ignaz Leitgeb (October 8, 1732 - February 27, 1811) was a virtuoso horn player and close friend of Wolfgang Amadeus Mozart.
It is generally believed that the Mozart Horn Concertos were composed specifically for Leitgeb in order to showcase his musical ability. Mozart put light-hearted comments in the margins, egging his friend on.de:Joseph Ignaz Leitgeb
