When Mei-Shun forgets how to play a score on Ms. Piano, it looks like a chance to her. Since fingering so far has been reset, she can try from scratch to find out better way. “Pavane …” is a good example, left behind Masters Bach and Debussy. And it seems that memory to play that musical instrument is saved not only in brain, directly connected with eyes but also in 10 fingers with necessary muscles.
