As a form of social consciousness, music has always held an extremely important position and role in the spiritual life of humankind. Furthermore, music strongly influences the material production activities of society. Music and lyrics are the two fundamental components that create the value of a song. Although each element has independent values, when combined to create a song performed by a human voice, the relationship between melody and lyrics is close, supporting and enhancing each other. However , there are special cases where the melody of a song is arranged for instrumental performance, or when the lyrics are "separated" independently for the artist to perform in the form of recitation or reading, the lyrics themselves are still considered an important part of the song's value. Vietnamese music also exhibits both the rules and specific characteristics of its linguistic culture.
