Abstract: Gongchepu has played a role never to be obliterated in the fact that Nanyin can prevail over thousands of year. As a symbol of sound in Nanyin, its music score precipitates profound scientific communicative thought. However, there are no studies in the academic circles over the years. Therefore this paper tries to fill the gap. By exploring the music score in terms of communication, we can perceive that it is not merely an information carrier, but also has far-reaching significance. Meanwhile, to deepen the research on its communicative method, mode, law and function of message will be very significant for the deepening of theoretical research on China's music communication.
