As a renowned local Sichuan opera mainly prevailing in Southwestern China's Sichuan province, Sichuan Opera is characterized by unique solos, refined acting, rich percussion, and talented comedians, whose skills are unparalleled in the world. The opera's application to be enlisted as an Intangible World Heritage is currently pending. 
Sichuan Opera features vivid, humorous narration, singing, and acrobatics. It also boasts a system of stylized movements and its acting is both exquisite and lively. Sichuan Opera performances are always full of wit, humor, lively dialogues, and pronounced local flavors. To portray special characters, the opera incorporates a series of stunts, including the famous "face-changing." In Chinese opera, facial makeup is usually painted, but in Sichuan Opera, the performer can change his or her facial makeup in the snap of a finger right on stage.
Chinese classMost Sichuan Opera repertoires are adapted from theical novels, mythologies, legends, and folk tales. Statistics show that the total number of Sichuan Opera plays exceeds 2,000. 
Sichuan Opera is noted for its high-pitched tunes, accompanied only by percussion instruments and choruses, without wind or stringed instruments. In addition, this spectacular theatrical presentation features bright sets and costumes, plus a combination of music, dance, and acrobatics. Among China's current 300 local theater traditions, Sichuan Opera has thrived and developed throughout ages as a distinct regional art form.
Its special characteristic -- one that distinguishes Sichuan Opera from other theatrical traditions -- is its immense vitality and dynamic performances that always strive to bring out an individual's artistic abilities into play to ensure fresh material, variety, and creativity. In part due to its intimate connection to a lively treasury of folk songs, Sichuan Opera reveals an extraordinary flexibility and vitality of expression in its music and movements.
The development of Sichuan Opera is intrinsically linked to the natural conditions in Sichuan. The principal agricultural products cultivated in Sichuan's extraordinarily fertile soil include rice, tea, and mulberry trees, whose leaves are used in the traditional industry of raising silkworms. Rustic songs originally sung by boatmen and tea-plantation and rice-paddy workers developed into famous local folk songs, which, in a sense, can be regarded as the precursors of the province's great operatic tradition.
Sichuan Opera "Changing Faces"
One of the most fascinating, artistic charms of Sichuan Opera is "face-changing," which is achieved by quickly tearing off, rubbing, or blowing away a mask to reveal another.
The performer prepares many special masks in advance made of gauze and elastic materials, such as sheep embryo membranes and rubber. After the masks are painted with different designs and assembled with a special transparent thread, they are pasted onto the performer's face.
The special masks for "changing faces" must be made to fit the performer's face to ensure that they are pasted as close as possible to the skin. Previously, the masks were discarded after a performance, but today they can be recycled with some minor repairs.
Musically, Sichuan Opera combines five different sonic systems -- gao qiang, hu qin, deng diao, tan xi, and kun qu --, all of which were still represented by their own independent troupes respectively until the end of the Qing Dynasty (1644-1911).
Founded in the province's capital city of Chengdu in 1912, the Sanqinghui troupe officially combined all five of these systems and fused them into a unique system of acting, singing, and instrumental music, where all of the librettos were written in the Sichuan dialect. The best-known style with most distinct characteristics of southwestern China is called gao qiang, which is distinguished by solos that are usually accompanied by sparse rhythmical accentuations played with wooden clappers. 
This highly ornamental vocal style is distinguished by brilliantly artful glissando links, skillfully implemented vibrato embellishments around a single tone in the form of a delicately elegant yet energetically melodic ornamentation. The simplicity of the folk songs' melodic structures is often retained.
In addition, an orchestra chorus either comments on or repeats what has already been sung. A solo can also represent the chorus. In the past, members of the chorus also often doubled as percussionists and, like the percussionists, were clad in everyday garments and appeared in full view on stage. Nowadays, they perform in the orchestral area, which is situated along one side of the stage and is concealed from the audience.
The barbarian fiddle, or hu qin, was probably brought to Sichuan by the famous Peking Opera, where shrill-stringed are instruments are predominant. On the other hand, the masked theater known as deng diao, which evolved from exorcist ceremonies practiced in the villages, is clearly of Sichuan origin. Deng diao was only accepted very gradually and with much hesitation from professional performance troupes. Removable masks are distinct from the painted masks, which are traditionally worn by performers on stages elsewhere in China. 
Alongside the dominant dialogues there are also numerous old folkloric themes that were typically heard in the past at rural festivals, weddings, and funeral processions. The accompanying instruments are primarily small drums and gongs.
Itinerant troupes from northern China probably brought the clapper element, tan xi, to Sichuan. This style is characterized by cunning, emotionally fraught rhythms played on wooden clappers, accompanied by the so-called "moon guitar."
The fifth stylistic element in Sichuan Opera is called kun qu. It originated in the southern Yangtze Basin and was later imported to Sichuan as a variant of the traditional and respected Kun Opera, with its discriminating literary dramas and fluent, highly artful melodies. The dominant melodic instrument here is the bamboo flute (di zi).
A single theater piece of Sichuan Opera usually combines two or three of the abovementioned musical styles. Only very rarely do all five systems appear together. The gao qiang style is the most frequent and its structure is most clearly developed.
