I'm sorry, I couldn't find any lyrics for the song "大凉山之晨（长笛+钢琴伴奏）" in the web search results. It seems to be an instrumental piece composed by a Taiwanese musician named 牧民音乐[^5^]. You can listen to the song on Bilibili[^5^] or watch a video tutorial on how to play it on flute and piano[^3^]. If you are interested in learning more about flute and piano accompaniment, you can also check out some articles and videos on 5sing[^4^] and 知乎[^6^]. I hope this helps. ?
