琵琶语 (Voice of the pi’pa) is a melody by Chinese composer Lin Hai 林海, originally written for the traditional Chinese instrument pi’pa.
I played that a lot accompanying a Chinese pi’pa player, and then I made my own arrangement for classical guitar.
The tremolo part is my free improvisation.
I am writing the score at the moment, after receiving many requests. If you are interested, please feel free to contact me.
