An intro introduces the singers, sets the pace, and establishes the melody. A good intro should catch the listener's attention and not overwhelm them. In addition to creating an impact, a good intro should contain a hook.

A pre-chorus is the section between the verse and the chorus. It is often filled with a chord progression from the verse. This builds anticipation for the chorus and heightens the impact of the chorus. Usually, the same songtext are used in the pre-chorus as in the chorus.

A chorus is the summation of all the big ideas in the song. This is often the most memorable part of a song. The chorus also serves as a summary of the emotional heart of the song. It should be a high point on the musical scale and should reflect the release of tension.

A pre-chorus usually contains a different melodic structure than the verse. This can be a unique melody or a variation on a previous melody. Whether it is a variation on the melody or a new one, the pre-chorus is a key component in defining the chorus.

Often, the song title is used in the chorus, but this isn't always the case. For example, the title of Taylor Swift's "All too well" appears in the first line, but not in the last. Alternatively, the title of Bohemian Rhapsody appears in the first line, but not in any of the verses.

As a rule, the most memorable line in a chorus is often the hook. Sometimes, the hook is the only line in the chorus. However, a well-constructed lyric will reference feelings as much as the melody. Moreover, a songwriter can use a cleverly constructed lyric to subvert the meaning of the entire song.

There are many successful song structure variations. Some have been popular for centuries, while others have worked for specific genres or time periods. Pop music is revitalizing traditional lyrical phrases with new melodic and harmonic combinations. Fortunately, the music industry has standardized on a number of song structure elements.

A good song is a song that has a strong chorus and a good verse. A bad song is one that uses words that are not worthy of the matter. While it's possible to make an effective chorus with no verses, it's better to create a song with more verses. One of the best exercises in songwriting is to try to compose a song with a song structure that you recognize.

Most pop hits feature two or three verse sections. Great songs may have shorter verses or longer ones.
