Mei-Shun has put scores of “Habanera” and “La Cinquantaine” under her favorite “Clair de Lune” composed by Master Debussy, thanks to 3-month practice. Their melody began to flow, allowed to join others including “Jesu, Joy of Man’s Desiring” for Shin. It is perhaps eyes and fingers who learn which keys should be pressed, ears and brain memorize harmony.
