(I) The name and popular scope of the folk instrumental music "Da Liu Zi": Da Liu Zi is popular in the Tujia people's settlement area in Wufeng. "Da Liu Zi" has different names in different regions in Wufeng. In Wantan Town, it is called "Chou Liu Zi"; in Renheping Town, people call it "Da Liu Zi", "Da Jia Ye", "Shi Pan Gu", "Qing Jia Ye" and "Qing Luo Gu Jia Ye", etc.; in Yuyangguan, Wufeng Town and other places, it is called "Da Liu Zi", "Wei Gu", "Da Jia Ye", "Da Dian Zi", etc. (II) Performance characteristics of the folk instrumental music "Da Liu Zi": The folk instrumental music "Da Liu Zi" is a form of gong and drum performance, but it is different from gong and drum performances in other places in that it uses double cymbals. They are cleverly coordinated. In one beat, the first cymbal and the second cymbal hit different rhythms, and they never make mistakes. It uses a unique gong and drum performance form with various forms, flexible techniques and full use of changes in speed, timbre, strength and rhythm to organically connect various tunes into a set, and with the musicians' superb performance, it can show various vivid images and interests. The band consists of 5 people, and the instruments include drums, gongs, horse gongs (sometimes hook gongs are also used), and double cymbals (head cymbals and second cymbals, also known as upper and lower hands). The timbre of the double cymbals is slightly different, one high and one low, one bright and one dumb, forming a contrast. With the tacit cooperation and skilled playing skills of the musicians, it can produce a short and dull "bu" sound, or a sonorous and pleasant "qi" sound and a dynamic "ke" sound. The double cymbals can also produce colorful and beautiful timbres according to the speed, strength, tightness and looseness of the rhythm, and the different parts of the cymbals, making them extremely expressive and imitative; the double cymbals mostly imitate birds and animals, and many tunes are named after the movements of animals, such as "Yan Ping Chi", "Phoenix Nodding", "Phoenix Spreading Wings", "Dragon and Tiger Fighting", "Dragon Wagging Tail", "Cold Duck Playing in the Water", "Carp Board Seed", "Hungry Dog Jumping on Food", etc. The rhythm of the daliuzai is fresh and bright, and the beat changes frequently. The music is mostly based on one beat, with changes in multiple beats in between, but the essence remains the same. The beginning and development of the music paragraphs and the changes in the board style often use 1/4 beat conversions. Its characteristics are smooth and free, with a sense of movement and stability. The drummer is the conductor, who is generally older and more skilled. The drummer's drum beats are unpredictable, sometimes airtight, as clean and neat as frying beans, sometimes as clean as a pool of water, never mixed, as if appearing and disappearing mysteriously, the drum beats are complex and beautiful, and he also has to make patterns on the drums while beating the drums to indicate the next tune; the hook gong and the gong seem to be one yin hammer and one yang hammer at first glance, but if you listen carefully, it is precisely because it cleverly avoids other instruments, appearing in the gaps between the gong and the cymbals, and in the gaps between the rhythms.
