Some combination of scores help Mei-Shun to play Ms. Piano more smoothly. For example, Waltz Op. 64-1 or “Valse du Petit Chien” composed by Master Chopin leads to easier “Le Cygne” by M. Saint-Saëns. “Pavane pour une Infante Défunte” by M. Ravel also works for “Jesu, Joy of Man’s Desiring” by M. Bach. Since tempo is all different between the former, fingering might matter.
