You can choose something more affectionate. Personally, I prefer the Japanese composer Zong Cilang's Back to Vietnam and the Original Scenery of My Hometown. If you choose the classic soundtrack, I recommend the famous classical song Canon. Shelley's poems will be full of charm with this tune. In addition, you can refer to China's classical music "Wild Goose in Pingsha", "Snowflakes in Cold River", "Yan Yan Mud", "Autumn Moon in Pinghu" and "Cloud and Water Zen Heart". These poems have a long artistic conception, so you can consider them. I hope it helps you.
