Zhao Rong had a headache. He possessed a good memory, almost to the point of being able to remember everything he saw—a large number of guqin scores were committed to his memory.
As for finger techniques, Zhao Rong had also practiced them... After getting a handle on the strength required, his somewhat careless strumming was actually quite skilled.
Therefore, playing the ancient guqin was not difficult for him once he had memorized the score and followed the patterns.
The difficulty lay in the fact that he discovered he was "tone-deaf," a realization that Yu Huaijin had also come to.
Zhao Rong couldn't distinguish between the loudness or pitch of the five notes and twelve tones in the music of the guqin.
This resulted in his inability to control the overall rhythm of the piece he was playing.
It was like knowing all the lyrics to a song but singing off-key.
The Art Class with Teacher Si ended amidst the harrowing sounds of someone torturing the guqin.
