Country folk is a hybrid sub-genre of country and folk music closely associated with the singer-songwriter and folk rock sub-genres. It is generally characterized as a component of the progressive country style and has its roots in the recordings of folk artist Bob Dylan. Country folk has been described as a mellower and gentler form of country music with more emphasis on song writing than vocals. Many of the artists described as country folk are respected more in mainstream country circles for their song writing abilities. The lyrics of the songs tend to be more thoughtful and emotionally complex than mainstream country.
