Guqin - 卧龙吟 Wolong Yin cover
I was delighted to learn only after getting into Three Kingdoms that the second song I learned on Guqin was Zhuge Liang's theme. The title is translated literally as "Sleeping Dragon's song." The lyrics for the original song are so melancholic, from the view of a departing Daoist hermit out to change the world and never to return to his humble abode of reclusion.
