Rhythm, also known as the tempo or meter, is the timing that makes up the driving beat behind the song. Rhythm can be a specific expression created either by harmony, such as rhythmic guitar strumming, or by drums.

Every song is made up of a specific structure.

When this musical form is repeated, each subsequent verse has different lyrics while the lyrics of the chorus remain the same. Every thought and feeling musically and lyrically relates back to this principal moment. It is the part of the song that the casual listener most easily remembers and therefore, for marketing purposes, is usually the part that generates the song title.
