The general structure of pop songs is verse (Verse) (A), chorus (Chorus) (B), transitional sentence (insert sentence) (C), popular sentence (memory point) (D) ), bridge (Instrumental and Ending) (prelude, transition, interlude) (E), etc. Generally speaking, the single and two-part form is the most common. The verse can be said to be the content, the backbone of every piece of music. The structure of music has a specific type, which is called Form in music theory. Most of the ordinary songs are in AA'BA' form. A represents the verse and B is the chorus. That is to say, the structure of a song is usually composed of an intro, two verses, a chorus, transition music, another chorus and verse, and ending music sequentially. There are many different types of Form, such as Blues Form, Jazz Form; there are even more Forms in classical music, such as Sonata, Ternary, Rondo or Rondo-Sonata, etc. The terms related to Form are what we accidentally see next to the title of the work on the record sleeve. of words. After the chorus is played, there is music to follow. A fill-in may be an adaptation of the verse or chorus, a certain melody from it, or even the melody of the intro. The most challenging thing is a musical transition and prelude. The melodies of the verse and chorus must not be similar, but they must not be off topic. It turns out that just by listening to the music, you can appreciate the skill of the arranger or composer. Before the end of the whole song, there is usually a piece of pure music (Ending) to complete the song. For example, repeating the last line of the song once, or repeating it multiple times and gradually lowering the volume until there is no sound at all (Fade Out), are some of the commonly heard ending expressions.
