In mid-1979, Krauss's mother saw a notice for an upcoming fiddle competition at the Champaign County Fair, so she bought a bluegrass fiddle instruction book and the 1977 bluegrass album "Duets" by violinist Richard Greene. Krauss learned by ear to play several songs from the album, including "Tennessee Waltz" which she practiced on violin with her mother accompanying on guitar. Krauss entered the talent contest in the novice category at the age of eight, placing fourth. (This is where she first met fiddler Andrea Zonn who won the junior division at age 10.) Krauss investigated the bluegrass genre more thoroughly after this, and she developed a knack for learning complex riffs by ear, quickly turning them into her own version. In 1981–82, Krauss performed with Marvin Lee Flessner's country dance band in which she fiddled and sang. In September 1983, her parents bought her a custom violin made by hand in Missouri – her first adult-sized instrument. At 13, she won the Walnut Valley Festival Fiddle Championship, and the Society for the Preservation of Bluegrass in America named her the "Most Promising Fiddler in the Midwest". She was also called "virtuoso" by "Vanity Fair" magazine.
