In addition to the two main streams of Kunqu Opera, there are Hunan "Xiangkun" and Wenzhou "Yongkun", as well as Kunqu Opera aria and instrumental tunes absorbed by multi-voice operas. For example, in Sichuan Opera, Kunqu Opera is one of the components, which has five vocal cavities: Kun, Gao, Hu, Dan and Deng. In Sichuan Opera, there are not only Sichuan-Kunming repertoires, but also the Kunqu opera singer "Kun Tou" with other voices. As for the percussion tunes and gongs and drums used in Kunqu Opera, they are common in other vocal operas.
