The Yellow River Haozi is an ancient Chinese folk song. In ancient times, people shouted when they were fighting against nature; when they were harvesting, they happily knocked stones and sticks, and the cheers and singing formed the prototype of the earliest Chinese folk song labor song. Haozi originated from labor and served labor. It is not only a tool for labor, but also an ode to labor. Its cultural connotation and social function are obvious. Some Haozi express the complex emotions of laborers, some reflect the characteristics of the geographical environment, and some describe the folk customs. The formation of Haozi is closely related to local folk customs. It is not only a manifestation of the ability of laborers, but also a profound accumulation of the long history and culture of the region or industry. The unique Haozi has had a glorious page in the history of modern Chinese music. For example, the first movement of the Yellow River Cantata, "Yellow River Boatman's Song", which was born during the Anti-Japanese War, adopted the form of a labor song. Its distinctive national style, strong breath of life and artistic appeal have greatly inspired the national spirit. In recent years, the "Chuanjiang Haozi" and "Yellow River Haozi" have been listed in the list of national intangible cultural heritage by the State Council for protection and inheritance. The Yellow River Haozi is a kind of labor Haozi. In the fight against floods, the ancestors of the Han nationality worked together and gradually formed a sound (Haozi) with a certain rhythm, certain rules, and certain ups and downs. The Yellow River Haozi was born in the "Hi Yo Hi Yo" of our ancestors. Different types of work appeared in the process of Yellow River management, and the Yellow River Haozi was also divided into many categories accordingly, such as rescue Haozi, tamping Haozi, boatman Haozi, soil transport Haozi, pillow bundling and pillow pushing Haozi, etc. Different schools appeared in different regions, and various Haozi were colorful and gorgeous. According to the "Song History River Channel Records", "When hundreds or thousands of Dingfu are used, they sing and pull together, and pile them up in low places, which is called sweeping the bank." This kind of "miscellaneous singing" is Haozi. Artistic characteristics The Yellow River whistle is a major carrier of Han folk songs. It has the practical function of coordinating and directing labor. It is sung by people when they participate in labor with strong collective cooperation in order to unify the labor rhythm, coordinate labor movements, and regulate labor emotions. The dual functions of the Yellow River whistle are: on the one hand, it can inspire spirits, regulate emotions, organize and direct collective labor; on the other hand, it has a certain artistic expression value. The relationship between the two is mutually restrictive and mutually exclusive. The greater the intensity of labor, the greater the restriction on the musical expression of the Yellow River whistle. On the contrary, if the labor intensity is low, the singers of the Yellow River whistle can have more spare energy to consider and exert the artistic expression of their music. Rhythm is one of the main characteristics of the Yellow River whistle. The continuous repetition of labor movements and their sense of rhythm give the rhythm of the Yellow River whistle a rhythmic nature. One leading and many following is another main feature of the labor whistle music. The most common and typical singing method of the Yellow River whistle is one leading and many following, and the leader is often the conductor of collective labor. The leading part is often the main part of the lyrics. The music is flexible and free, and the tune and lyrics are often improvised. The melody is often upswing, high-pitched and loud, with the characteristics of calling and appealing. The chorus part is mostly the backing words or repeated fragments of the leading part. The music is relatively fixed, with few changes and a strong sense of rhythm. The same music or the same rhythm is often used for repetition.
