Answer:
By employing this folk style in his own original compositions.
Step-by-step explanation:
I argue that Bartók’s efforts established the field of ethnomusicology because he was one of the first musicians to branch into the study of ethnic music by traveling to collect samples of music, by aural recording and transcribing folk tunes, by re-writing these songs into understandable notation with new harmonization, and by then employing this folk-style in his own original compositions.
Hope this helps:)
