The Yi musical instrument "Mabu" has a unique personality and distinct local characteristics in Yi folk musical instruments. It has an ancient tradition, is widely spread, and is deeply loved by the Yi people. [Date of Origin] Mabu has a long history of circulation, and there is no accurate record of its origin. From the perspective of instrumental music, Mabu is a bamboo tube reed instrument, which has a connection with the origin and evolution of the ancient "Jia" and "Bihu" in my country, and is similar in shape to the ancient Qiang people's musical instrument "Qihu". The Yi people originated from the ancient Diqiang, so Mabu has existed since ancient times. [Distribution Area] Mabu is mainly spread in Yuexi, Zhaojue, Ganluo, Meigu, Xide, Yanyuan in Liangshan Yi Autonomous Prefecture, Panzhihua City, and Yi concentrated residential areas in Ya'an area in Sichuan Province, in addition to Ninglang Yi Autonomous County in Lijiang District, Yunnan Province. Among them, it is more widely spread in Yuexi and Zhaojue, mainly in Shenguozhuang, Puxiong, Chengguansuozhong, Shunhe in Yuexi County and Zhuhe, Sikai, Jiefanggou and other Yi ethnic gathering areas in Zhaojue County. There are excellent Mabu players in each branch area. [Basic content] "Ma" means bamboo and "bu" means reed pipe in Yi language, which means bamboo wind instrument with reed pipe inserted, also known as "bu ra". The pipe body is made of bamboo pipe, and the whistle is a single reed. The pipe body is mostly made of a bamboo pipe that is transparent from top to bottom, with a length of 1522 and an inner diameter of 0.60.9. It has five to eight circular sound holes and a bell made of ox horn at the lower end. A thin bamboo pipe whistle mouth is inserted at the upper end of the pipe mouth, and a 2.5-long reed is opened on the whistle mouth, with the tip of the tongue facing up. When playing, the body of the pipe is placed vertically, the index finger, middle finger and ring finger of the left hand press the upper three holes, the index finger, middle finger and ring finger of the right hand press the lower three holes (plus the little finger can press 4 holes), the mouthpiece is held in the mouth, and the whistle is played with circular breathing. The performer presses the reed with teeth to shorten its vibrating part, and the range can be expanded to 12 to 14 degrees, which can meet the needs of performance. The timbre of Mabu is crisp and melodious, full of field flavor. The timbre is rounder and softer than that of the small suona, and has some of the color of the Western musical instrument oboe, and has the special flavor of suona and oboe. The Yi people compare it to the sound of cicadas, which really has a feeling of intoxicating autumn sounds and colors. In the past, it was used for solo performances, and it is a distinctive and expressive instrument. When it is used to play cheerful and lively melodies, it is loud and rough; when it is used to play sad and slow tunes, it is affectionate and slightly nasal; especially when playing the long tail, the music is like crying and complaining, which is very moving. Mabu music is often developed with customary tunes. The performers can be moved by the scene and play according to their feelings, and play colorful music. Long notes with varying strengths and weaknesses, rapid repetition of the same note, rapid finger tapping, frequent appoggiatura, downward glissando and ornamental notes are widely used in the music. The calls of various birds and beasts are often simulated in the music. Traditional Mabu solos include "The Tiger Out of the Cave", "Cuckoo Crossing the Mountain", "Morning Breeze Shaking Bamboo", "Ten Thousand Horses Running on the Beach", etc. Popular Mabu music in Yuexi and Ganluo include "Sheep Herding Tune", "Letting Dogs Chase the Mountain", "Harvest Tune", "Late Pastoral Tune", "Mountain String Tune", "Happy Tune", "Sad Tune", etc. Among the Yi people in Liangshan, Mabu is widely used in festivals, celebrations and leisure time in daily life, and is also used in funerals. This custom is popular among the people: when parents die, married daughters invite the best musicians in the village to play Mabu at their mother's house to express their deep remembrance. During festivals, celebrations or after work, the young men of the Yi people like to play Mabu to relax and entertain themselves. Now "Mabu" is not only often used for solo performances, but also used in ethnic bands. [Basic characteristics] 1.
