In the past, there were no radios, mp3 players, nor iPads. However, folk music already existed. Folk music is a traditional music, usually heard in rural areas. The music was used to be passed down to descendants or other people within their small society. Like any other form of literature, folk music started through aural transmission before writing the melody and lyrics became a trend. A person would teach someone the whole music and this would be passed to another person.
