동요 is a genre of Korean children's songs that often feature simple melodies and lyrics. These songs are designed to be easy for children to sing along with and typically convey themes of nature, friendship, and childhood experiences. The history of 동요 dates back to the early 20th century, with many songs being inspired by traditional Korean folk music. Notable composers, such as 윤석중, have contributed to the genre, creating timeless classics that continue to be popular in schools and homes across Korea.
