What is "qinqiang"

Qinqiang (秦腔, pinyin: Qínqiāng) or Luantan (亂彈, pinyin: Luàntán) is the representative folk Chinese opera of the northwest Province of Shaanxi, China, where it was called Qin thousands of years ago. Its melodies originated from rural areas of ancient Shaanxi and Gansu. The word itself means "the tune or sound of Qin".

The genre uses the bangzi (woodblock) as one of the accompanying instruments, from which it derives its other name, Bangzi opera. Bangzi tune is the oldest, most affluent opera tune in China's Four Great Characteristic Melodies. Qinqiang is the representative of the Bangzi opera and the most important origin of other Bangzi operas.

Tan Dun, the composer for the opera The First Emperor, researched Qinqiang for the opera, in order to learn more about "ancient Chinese vocal styles".
