What is the name of the background music of Cangyang Gyatso’s lover Rigzin Wangmo’s poem?

Dawa Dolma Tsangyang Gyatso built an exquisite pavilion called Longwangtan on a small island in the lake in the forest garden behind the Potala Palace, where he invited young men and women from Lhasa to Singing, dancing, drinking and carnivaling together, Tsangyang Gyatso wrote many love songs for everyone to sing. These love songs soon became sung in Tibet and were very popular among people. In the Dragon King Pond, Cangyang Gyatso met a girl from Qiongjie, named Dawa Dolma. Dawa Dolma had a beautiful appearance, a gentle temperament, a sweet voice, and a pair of big black and bright eyes that looked like they had just been brewed. The wine can make you drunk just by looking at it. Tsangyang Gyatso and her knew each other very well, as if one was the shadow of the other. They sang, danced and played together during the day and often had trysts at night. Tsangyang Gyatso liked Dawa Dolma very much and thought it was a gift from the gods and a fate in his previous life. He wrote such a song to express his feelings:

Lhasa is densely populated and full of people. The beautiful person I love is from the land of Qiongjie

As the saying goes, sweet barley often turns into bitter wine, and happiness often turns into sorrow. Later, Tsangyang Gyatso discovered that Dawa Dolma had not come to the Dragon King Pond for several days. He sent her a message to make an appointment, but there was no reply like tsampa scattered in the water. He personally visited her residence and saw a hanging hanging on the door. A big lock, and after asking the neighbors, I found out that Dawa Dolma had been taken back to Qiongjie by her parents for many days. Tsangyang Gyatso seemed to have lost his beloved treasure, and felt very sad. When he was lost and depressed, he wrote the previous song "Don't Say Qiongjie Qiongjie Again". From then on, Cangyang Gyatso never saw Dawa Dolma again and became the lover of his dreams.
