Concerto for Flute, Harp, and Orchestra
Mozart was living in Paris at the time he wrote this concerto. He wrote it for the flute-playing Duke of  and his harp-playing daughter Marie.  Mozart never liked either instrument. The combination is a difficult one for duo. The work is pleasing and popular however. It is a favorite with harpists because there are so few concertos for harp. The Duke failed to pay Mozart for the concerto.
