Dance
The
feature of the dance of K-POP is called "Kal-gunmu" in Korean, which
means the dance which matces the very sharp movement of the body and even the
movement of fingertips.
The dance of BTS is a very good example of Kal-gunmu, especially before 2016.
By the way, I am in K-POP cover dance club in my university, called
"Mayl Mans" and we copy BTS. Please watch our videos if you have time!
