Folk-Pop falls into two categories. Either it is folk songs with large, sweeping pop arrangements, or pop songs with intimate, acoustic-based folk arrangements. Folk-pop began to evolve in the early '60s, but it came into full force after folk-rock became a sensation in the mid-'60s. Folk-pop doesn't have ringing guitars and rougher edges of folk-rock; instead, it is softer, gentler, and more pop-oriented.
