 The first discipline selected was cello, since Yun was a famed cellist, and he had composed his first concerto for cello in 1975–76.The organizers then selected violin and piano, because those were the top two disciplines to present the highest quantity of international competitions, and because Yun wrote many works involving those two instruments.They also found that after one cycle of three editions, the winners had an opportunity to collaborate and play in piano trios.
