"The section you played," Bai Lian raised her right hand, touching the strings to demonstrate a part in the middle, "it can be more explosive."
"It's not about the strength of the fingers, but the power of the arm and the wrist, you need to lift your arm." Bai Lian looked up and demonstrated the section again, her fingers hooking the strings, her wrist and arm gathering strength—
"Zeng—"
The tone instantly elevated.
"The following part is in the bass, shift the focus forward, and the wrist must move too, to produce a resonant vigor." She was originally using the guzheng for her composition, and the strings would erupt in full force once plucked.
Playing the guzheng also required strength in the wrist, arm, and waist, and Bai Lian had a natural talent for it.
It's said that the guzheng and pipa are two formidable instruments, but mastering the rhythm required to bring out this kind of "killing aura" is the most difficult aspect to control.
