Answer:
Virginia, North Carolina, Kentucky and Tennessee
Step-by-step explanation:
Cecil Sharp travelled through the Appalachian mountains in Virginia, North Carolina, Kentucky, and Tennessee. He and Maud Karpeles recorded many folk songs, often covering many miles on foot over rough terrain. They recorded over 500 ballads with English roots between 1916 and 1918.
Sharp was the best-known collector of English folk music. He collected almost 5,000 folk songs and tunes, far more than any other English collector.
