Yunjin tried to directing a certain emotion, a certain pronunciation in some words, a certain style of singing like use head voice in some part and more bright voice tone with smile.
Excluding Yunjin, Chaewon is the best singer and easier to understand the directing, the second is Kazuha, third is Sakura, and fourth is Eunchae. But Yunjin seem did not use term of vocal technique that usually used in English speaking language. I don't know they learn the theory of vocal technique or just learn only practical aspect. Definitely, Yunjin know about vocal technique.
I fell in love with Zuha's voice during this lol
Its just that Sakura is so much more beautiful without makeup

It helps that she knows the other members well and what kind of direction they will respond to
