The competition's coming up. Kumiko is suddenly asked to play a difficult phrase from a different part. She begins practicing, but...
I'll get better while I play.
سأتحسّن بينما أعزف
Beim Spielen wird’s besser.
Sanará mientras toco.
Se curará mientras toco.
Ça passera en jouant.
Andrà meglio mentre suono.
Me recupero enquanto toco.
