When Béla Bartók wanted to pursue his own musical direction after the conservatory, he found more and more inspiration in Hungarian folk music. Together with his friend Kodály he traveled across the Hungarian landscape, which included parts of what is now Romania, recording and collecting folk music. In 1906, he published his first bundle, making his research on folklore become his biggest passion. Even in Turkey and Africa he explored all kinds of music, collecting over 10.000 folk songs during those years. Bartók deliberately incorporated lots of these folk influences from Hungary into his own compositions. However, he found his own personal style, marking his signature on a lot of modern music. For example, in his six-piece cycle titled Romanian Folk Dances, which was initially composed for piano solo. Bartók simplified the rhythmical irregularities of the original melodies, and enriched the harmonic structure to his own liking.
