The Flute Concerto no. 1, K. 313 was written in 1778 by Wolfgang Amadeus Mozart. Commissioned by the Dutch flautist Ferdinand De Jean, Mozart was supposed to provide four flute quartets and three flute concerti, yet he only completed two of the three concerti: K. 313 being the first. The Andante for Flute and Orchestra, K. 315 may have been written as an alternative slow movement for this concerto. The piece is scored for a standard set of orchestral strings, two oboes (which are replaced with two flutes in the Adagio movement), and two horns. The opening of the second movement is often known as resembling the famous theme from the Blue Danube Waltz by Johann Strauss, Jr., which was composed many years later.
