14 Bagatelles, Sz.38, BB 50; 3rd Set, Op. 6 (Hungarian: 14 Bagatell) is a set of pieces for solo piano by Hungarian composer Béla Bartók, written in the spring of 1908 and first performed by the composer June 29, 1908, in Berlin. The work was published the following year in Budapest by Rozsnyai Károly. Composed the same year as Ten Easy Pieces, 14 Bagatelles was experimental and signified Bartók's departure from the tonality of 19th century composition. The work borders on atonality, and Bartók adopted some techniques of Debussy and Schoenberg.
