The piece blends elements from the West with the East, depicting birds in flight. Many harmonies and intervals in the tune are built on fourths and pentatonic scales, which evoke Chinese music. Many gestures in the piece originate from the Chinese flute, which often uses extensive grace notes and quick dynamic changes within a single phrase. The fast note passages represent the swiftness of birds as they fly through the air. Nature—especially mountains and water (山水畫)—is often a central theme in Chinese painting. The tune conveys the scenery of mountains and rivers, depicting the natural environments where birds reside.
