Salty Water Songs are popular in Daliang, Jun'an and other areas of Shunde, and are mainly sung by water dwellers (Danjia). They are also known as Salty Water Sighs, Danjia Songs, and Houchuan Songs. They flowed in during the late Ming and early Qing dynasties and were very popular in the 1930s and 1960s. There was a saying that "the wind blows, and the big talk is salty." Shunde Salty Water Songs can be divided into categories such as split-character songs, duet songs, and ancient people's songs. Their structure, melody, and rhythm are quite local. Its structure is divided into "long-sentence Salty Water Songs" and "short-sentence Salty Water Songs." There are solo and duet forms, with duets being the main form. Duets are in the form of male and female answers. The lyrics are not rigidly composed, but basically maintain a compound music section of four sentences. Its melody is flexible. Except for the beginning of the song, the pause in the middle, and the end of the song, which are basically fixed, the melody in the middle is expressed around the main tone in a second degree progression, ascending or descending, adding or reducing flowers. The rhythm of the song is composed of eighth notes and sixteenth notes alternately, and dotted notes and syncopated notes appear due to the needs of language and emotion. The beats are mostly 2/4/ or 3/4, and there are also mixed beats. The salty water song has important value in musicology, linguistics, folklore, etc. The melody is free, the rhythm is beautiful, and the rhythm is free and unrestrained. The same singing style of "Xianshui Song" can make appropriate adjustments to the melody except for the beginning, end or dragging of the song, which shows the freedom of folk music; Xianshui Song is sung casually, often using local dialects, with a strong colloquial color, and its "one word one sound" form is closely related to the language tone. The old-style Xianshui Song that is still sung now retains a lot of Shunde local dialect pronunciation; the creation and recitation of Xianshui Song is closely related to the production and life of Tanka people. Tanka people create Xianshui Song based on their own production and use it to make friends, express feelings, and express their pain and joy. Xianshui Song involves all aspects of Tanka people's food, clothing, housing and transportation, and has important reference value for the historical research of Tanka people. In 2014, Xianshui Song was included in the fourth batch of Shunde District-level Intangible Cultural Heritage List.
