The basic structure of a song is verse, chorus, bridge and final chorus.

The main song of the first paragraph presents the initial part of the musical theme and sets the tone for the story to be narrated. It is the main part of the song, and the lyrics should briefly describe the main message of the song.

The second verse is expanded in detail to depict the theme of the song, further strengthening the connection between the first verse and the second verse. Usually the same melody as the first chorus, this is an opportunity to re-emphasize the theme of the song after the second verse.

Bridge and bridge music (pass-through) are very different from the verses and choruses. They are generally the climax of the song, or to build up energy and pave the way for the final chorus. Sometimes, it can also refer to an unexpected section that breaks out of the song structure, described as an interlude or transition. The final chorus returns to the core of the song and strengthens the theme of the song. Sometimes the final chorus is repeated twice.
