The Ten National Airs with Variations for Flute and Piano, Op. 107, were composed by Ludwig van Beethoven in 1818 and 1819. Beethoven wrote this piece based on folk-derived melodies. This is one of several sets of pieces that Beethoven wrote that are folk-derived. The piece was for George Thomson, a wealthy Edinburgh-based publisher with whom he had a difficult business relationship. These variation sets were first published in 1819 in both London and Vienna.
