Ferdinand David (1810-1873) was a german composer and virtuoso violinist. His Concertino for Trombone and Orchestra, Op. 4, was composed in 1837. It was dedicated to Karl Traugott Queisser, a good friend, who played in the Gewandhaus Orchestra where David was concertmeister. There are many myths about how this concertino came about, but the most probable version is that David rewrote one of his already mostly finished violin pieces into this trombone concertino.
