"Green" Pipa : Bionic instead of snakeskin leather

In addition to皇宝娱乐平台ing , in recent years , also with opera in the musical aspects of modern technology . In last year's bionic skin jinghu recital, Peking Opera and the audience to get to know a new thing - green jinghu .

Jinghu inseparable accompaniment of opera performances , before the mouth jinghu Qintong snakeskin covered with a thin, tough , after vibrating strings snakeskin spread , affecting air column vibration to sound. Good jinghu with crisp , crisp, bright , thick, pass characteristics. Snakeskin choice, largely determines the jinghu tone is complete , the size of the snake and the snake of time will also affect the snakeskin drawn . But snakeskin life is generally only two years , and are subject to environmental and humidity impact, especially in the high humidity, high temperatures in summer , in the south easily collapse skin, in the north and easy to burst, the need for frequent re- skin, so a lot of snakeskin is consumed.

More importantly, snakeskin jinghu on multiple uses of wild black sheath snake, a snake can only do 6-8 . Year there will be about ten million of pythons , snakes were hunted for Pipa and other instruments making, and these animals can eat 10 million a year rat .

Chou Meng Guanglu bluntly famous himself can not hear the difference between Pipa Pipa bionic leather and snakeskin , the highlight of his performance sound good no problem , "I will recommend to peers and musician who , after fighting for more than accompaniment bionic skin jinghu ."

But there are also famous jinghu pointed at the bionic skin jinghu still inadequate . Li Zuming think it sounds mellow enough ,燕守平believes bionic skin jinghu on the tail , the performance of some lingering problems , the need to constantly improve and enhance .
