What is musical form and why is it important? How can we determine the form of a song just by listening? In this lesson, learn the different parts that make up a musical form.


You are backstage, preparing to audition for the show So You Imagine You Can Dance. You are sweating buckets, your knees are shaking, and you can barely remember your name, but it's okay, because you do remember the dance steps you are about to perform for the judges. You know the steps of the dance because they are organized into sections. First, you have the Charleston knee knocks, then the cabbage patch, back to the knee knocks, a few quick disco points, and a grand finale featuring a jump into the splits. Since you arranged your steps in an order, we could say that you have created a form.

Form: Definition

Much like your dance, music is often organized into sections. The overall organization of these sections is called form. The form of a song shows its structure and can often help the listener relate to and understand what the composer intended to say.

Definition of Musical Sections

You hear form all the time. Think of your favorite song. Typically, the song has three sections: a chorus (or refrain), which sums up the song's topic and is repeated at times throughout the song; two or three verses, which explain or expand on the topic of the chorus; and a bridge, which adds a bit of variety to the music. When writing the song, the composer did not just pile all of the choruses together at the beginning, stuff a few verses in the middle, and end with a bridge. Instead, he or she followed a form.

There are several common arrangements of these sections. It can be as simple as Verse-Chorus-Verse-Chorus-Verse-Chorus, as you would hear in Eminem's 'Lose Yourself' or The Beatles' 'Let It Be,' or it can be more varied like Verse 1-Chorus-Verse 2-Chorus-Bridge-Chorus-Chorus, which can be heard in Justin Bieber's 'Baby' and Linkin Park's 'In the End.' In each of these examples, the composer used form to help the listener understand and make a connection with the song.

Section Naming Conventions

However, not all songs can be pigeonholed into having verses and choruses. Instead, we can use letters to represent the sections of a song. The sections are named alphabetically, so the first section of music would be called A. When a new section appears, we call it B. We continue this alphabetical naming with each additional section of new music. If a section of music ever reappears, we call it by its original letter name.

For example, in your dance, you had four unique moves. Because each move is different, each move will be labeled with its own letter. This will help us tell the sections apart from one another. The sections would be labeled A for your Charleston knee knocks, then B would be for the cabbage patch because it's a different move, C would be for the point, and D would be for the splits. When we analyze the form of the dance as a whole, we would have A-B-A-C-D.

Lyrics and Simple Form Analysis

While the music alone is enough to determine the form of a song, using lyrics can be helpful too. Even something as simple as 'Twinkle, Twinkle, Little Star' still has form. Let's take a look.

Twinkle, twinkle, little star, how I wonder what you are.

Up above the world so high, like a diamond in the sky.

Twinkle, twinkle, little star, how I wonder what you are.

Discussion Questions

For this activity, respond to the following discussion questions about musical form. For each question, write at least 2-3 sentences. Some questions have multiple elements, so make sure to answer every part of the question. Also, keep in mind that some of these questions may require additional research.

  1. What are the common musical sections? Explain the role of each of these sections in a song.
  2. Research the following song forms: bar form, 32-bar form, strophic form, and ternary form. Describe each of these forms in detail.
  3. Why is the purpose of musical form? Why is it important? Explain.
  4. Choose a song not mentioned in the lesson and explain its form. Then, label the sections with letters. What is the form of the song?

A Possible Answer to Question #3:

The purpose of musical form is to help organize a piece of music. Without musical form, a song would sound jumbled and disjointed. This is why a composer or song-writer must have a plan before they start to write their music/lyrics. In this way, writing music is similar to writing an essay. If you don't have a plan before you write, the final piece will likely be disappointing.
