If you don't like section, the other term used by people in the music biz is part.
The most popular songs tend to follow familiar patterns. While it’s possible to compose epic suites where no two parts are the same (looking at you, Dream Theater), most pop music sticks to traditional structures.
So, what are the structures often used in songwriting? First, let’s look at the parts that make up most songs... Chorus: The catchiest part of any song...
This can also be confused with the different usage of part which describes what each instrument is playing/vocalist is singing during each section, which is more common:
ABAB Form. This form, called “binary structure” involves toggling back and forth between a verse section and a chorus section.
ABABCB Form. This is also known as “verse-chorus-verse-chorus-bridge-chorus” form. In this style of composition, the A section is the verse, the B section is the chorus, and the C section is the bridge.
A bridge in songwriting is a section that differs melodically, rhythmically, and lyrically from the rest of the song.
Perhaps the most basic aspect of music theory is giving names to the sections of a song.
Let’s put some labels for these sections and define the common things that occur in each section
So, according to the music industry, section is the way to label the segments of a song with different music.
