A song is a musical composition that is performed with vocals or instruments. Songs are usually performed live and recorded on audio and video. They may be sung a cappella or in a more formal, structured setting.
In the modern world, songs are used in films, television shows, plays and stage productions. Many popular songs are composed by professional songwriters. The basic structure of a song includes an intro, a verse, a chorus and an outro.
An intro establishes the tempo and rhythm of the song. It also serves as a chance for the singer to introduce his or her voice. Typically, this section is slower and less pronounced than the rest of the song.
An optional pre-chorus can be placed before the chorus. It generally serves to heighten the impact of the chorus and introduce new melodies or harmonies. Pre-chorus lyrics are generally shorter than the verse.
The chorus serves to summarize the main themes of the song. This section is often the most memorable part of the song. Often, the title of the song will be included in the chorus.
Occasionally, a song will have a bridge or a coda. These sections are used to break up the repetitiveness of the verses and chorus. Bridges tend to occur between the second and third chorus.
The lyrics of the song are written to create emotion. They are based on a specific topic or a feeling. Depending on the style of the song, the melody is used to reference these feelings.
