Premise: Variations on a Korean Folk Song is a major musical piece written for concert band by John Barnes Chance in 1965. As the name implies, "Variations" consists of a set of variations on the Korean folk song "Arirang", which the composer heard while in South Korea with the U.S. Army in the late 1950s. In 1966 the piece was awarded the American Bandmasters Association's Ostwald Award.
Hypothesis: John Barnes Chance would have not have written Variations on a Korean Folk Song had he not visited South Korea while traveling with the Marine Corps prior to 1966.
