Wolfgang Amadeus Mozart''s Oboe Concerto in C major, K. 314 was originally composed in Spring or Summer 1777 for oboist Giuseppe Ferlendis (1755 1802) from Bergamo, then reworked by the composer as a concerto for flute in D major in 1778. The concerto is a widely-studied piece for both instruments and is one of the more important concerti for the oboe. The Flute Concerto No. 2 in D Major is an adaptation of the original oboe concerto. Dutch flautist Ferdinand De Jean (1731-1797) commissioned Mozart for four flute quartets and three flute concerti; which Mozart only completed three quartets and only one new flute concerto. Instead of creating a new second concerto, Mozart rearranged the oboe concerto he had written a year earlier as the second flute concerto, although with substantial changes to it to fit what the composer deemed flute-like. However, De Jean did not pay Mozart for this concerto because it was based on the oboe concerto.
