The first time I listened to the pipa, from the moment I heard it, the song brought me into a sad and euphemistic mood, which lingered. Listen to the pipa written by Lin Hai. Repeated preludes make people enter a state of lingering sadness and want to talk. The weak and sad sound of the keys, coupled with the unique characteristics of the oriental musical instrument pipa, makes people be dragged step by step, and finally makes people intoxicated in the artistic conception of music. During this period, violins, violas, pianos and flutes appeared and disappeared from time to time, which played a good role in harmony. It not only highlights the characteristics of pipa, but also further enriches the expressive force and thoughts and feelings of the repertoire. The most exciting and novel part of this song is the middle part of the song. Perhaps Lin Hai always has a feeling of giving up the piano. When the piano suddenly becomes the lead singer, the pipa becomes the accompaniment.
