The lyrics of a song are written to convey a message. They usually contain social or political themes, as well as aesthetic elements. Some parole de chansons are explicit, while others are meant to be implied. There are several ways to write lyrics, such as spoken word, singing, and rapping. A well-written lyric can express as much as a melody.
In the case of songs, a song's lyrics can include a story or a series of events that encapsulate an emotional experience. Often, these are expressed through metaphor or symbolism. This is especially common in pop music. For instance, the Beatles' song All You Need Is Love has a lot of religious imagery and references about the 1968 Chicago riots.
The lyrics of a song are typically grouped into three sections: the pre-chorus, the chorus, and the bridge. While the chorus serves to sum up the entire song's message, the pre-chorus is designed to heighten the impact of the chorus. It also builds upon the familiarity of the song, and introduces a new lyrical concept.
The pre-chorus typically contains the chord progression from the verse. It is one of the most common song structures found in contemporary pop hits.
