There are five main categories of folk music in my country, namely: folk songs, folk song and dance music, rap music, opera music and folk instrumental music. Under each category there are many smaller categories. There are many angles and methods for classifying folk songs in my country. For example, according to the theme and content of the words, they can be divided into labor, life, love, legends and stories, etc.; according to the generation period, they can be divided into traditional folk songs and revolutionary historical folk songs. , new folk songs, etc.; according to ethnicity or region, they can be divided into Han folk songs, Mongolian folk songs, Uyghur folk songs, Tibetan folk songs, or Qinghai folk songs, Xinjiang folk songs, Hebei folk songs, Henan folk songs, etc. In terms of the musical form of folk songs, my country's Han folk songs have two classification methods: genre and color area. The genre classification of Han folk songs is a method of classifying based on the artistic style of folk music. The genres of Han folk songs are divided into chants (including porter chants, boatman chants, workshop chants, etc.), folk songs (including general folk songs, herding folk songs, field folk songs, etc.) and minor tunes (including ballads, seasonal tunes, customs and rituals) Songs, dance songs, etc.) three categories. The color classification of Han folk songs is a method of classifying the local folk music. According to current research results, folk songs in various Han regions can be divided into Northwest, Northeast, Central Plains, Jianghuai, Fujian and Taiwan, Guangdong, Jianghan, Hunan, Jiangxi, Southwest, Hakka and other regions according to their style characteristics. The folk songs of my country's ethnic minorities each have their own traditional classification methods. Some of them are divided into hunting songs, banquet songs, pastoral songs, homesick songs, etiquette songs, narrative songs, religious songs, children's songs and rocking songs (i.e. lullabies) according to the social functions of the songs; some are divided into love songs, Labor songs, wedding songs, birthday songs, etc.; some are divided into "Dali Bai songs", "Eryuan Xishan Bai tunes" according to the characteristics of folk songs in various regions within the nation; some are divided into long tunes, short tunes according to the musical form of the songs. Adjust and wait. The research on folk song and dance music in my country's music industry started relatively late, and previous research in the dance industry mainly focused on dance movements. Therefore, there is currently no concentrated research and consensus on the classification of folk song and dance music. Among the scholars who have started to work on manufacturers, some start from the two categories of dance songs and dance music. Dance songs are further divided into seasonal tunes, ballads, chants, children's songs, polyphonic and drama genres; dance music is further divided into percussion music, wind music, plucked music, drawn string music, and comprehensive music. Wind and percussion music, string music and band ensembles, etc. In other words: dance songs are basically classified according to folk songs, and dance music is basically classified according to folk instrumental music. Some scholars first classify music by ethnicity. Among Han people, they mainly classify music from the perspective of southern and northern music, and from the perspective of large and small performances of singing and dancing, while ethnic minorities classify music based on self-entertainment, performance or rhythm type. According to the artistic style, the rap music of Han people in my country can be roughly divided into four categories: Pinghua, drum music, allegro, and cross talk. Among them, only drum music is a type of music. This part can also be roughly summarized into five categories based on the main instrument, historical origin, music style and characteristics, including drum lyrics, tanci, Taoism, brand music, and Qinshu. Another classification method is from the perspective of the structural form of rap music, which is divided into four categories: single style, Qupai couplet, Ban style variation and Qupai Banqiang hybrid. The rap music of my country's ethnic minorities is difficult to classify due to its complicated ethnic situation and historical origins. There are basically two classification methods for Chinese opera music. One is to start from the vocal tune, which is divided into four major tune systems and two major tune types, and six categories, namely, Kunqiang tune system, Gaoqiang tune system, Bangzi tune system, Pihuang tune system, and folk song and dance types. Tune system and folk rap type Tune system are two major types of tune. The second is to start from the musical structure types of opera, which are divided into two types: Qupai couplets and board variations. my country's folk instrumental music is mainly classified into solo music and ensemble music. Solo music is divided into three categories: wind music, string music, and plucked music; ensemble music is divided into three categories: string and bamboo music, drum music, and wind and percussion music. Some scholars also divide ensemble music into four categories: string music, silk and bamboo music, wind and percussion music, and clear gongs and drums.
