In a song, the chorus is king. It is the main section. It contains the hook of the song and usually the title. When well written, a chorus is what people remember the most. When taken together, the choruses of a song (usually) encapsulate the main idea of the entire song. Individually, each chorus sums up the section prior to it.
For the ease of description, I’m going to use some common songwriting conventions. First, choruses are 4-lines long. (In the “real world” choruses can be of any amount of lines!) Second, the hook and title of a song are the same thing and they are sung somewhere in the chorus at least once. (This also isn’t always true. For example: the title “Bohemian Rhapsody” is never actually sung in that amazing song!). I am going to refer to any line that contains the hook/title of a song as the “Title Line”. I will use the term “Swing Line” to indicate any line of a chorus that does not contain the hook/title,. The symbol for a Title Line is a capital T. The symbol for a Swing Line is a tilde (“~“). Combinations of Title and Swing Lines are called Chorus Forms.
The closing line of your chorus is a very bold place to reveal your Title/Hook. You show patience by putting your Title/Hook in a position to be heard last. Think about it, you are making your listener wait in anticipation as the lines build up and finally reveal the Title/Hook. Scientific studies show that a listener’s brain unconsciously emphasizes the last line. This emphasis (called the “Recency Effect”), is considered the 2nd most powerful position in a chorus.* This Chorus Form is terrific for indicating shyness and indecision, or it can also be used to present thoughtful consideration.
Examples of the ~~~T Chorus Form are: Somebody That I Used to Know (Gotye), Everybody Talks (Neon Trees), Clarity (Zedd), and Viva La Vida/ When I Ruled the World (Coldplay).
*(It doesn’t matter how many lines a chorus has, the closing line will always have the Recency Effect).
The opening line has been shown to have an even greatest impact on a listener than the closing line (called the “Primacy Effect”).The opening line is a very confident position for your Title/Hook. You immediately grab the attention of your listener. This Chorus Form is great for indicating a conviction to your main idea.
Examples of the T~~~ Chorus Form are: Fire and Rain (James Taylor), Royals (Lorde), Just Give Me a Reason (Pink/Nate Ruess), and Rolling in the Deep (Adele).
Even stronger than ~~~T and T~~~ is this wonderful Chorus Form. Listeners first hear the Title/Hook in the weaker 2nd line and they are ultimately satisfied by its repetition in the closing position (further strengthened by the Recency Effect). Your listener still has to wait for the Title/Hook, but not as long. This Chorus Form can be very intimate.
An example of the –T~T Chorus Form is: Brave (Sara Bareilles).
This Chorus Form takes the strength of the ~T~T and ramps it up another notch. Listeners are treated to the Title/Hook from the get go. This Chorus Form revels in self-assurance and confidence.
Examples of the T~T~ Chorus Form are: Bang Bang (Jessie J, Ariana Grande), Fancy (Iggy Azalea), Take Me to Church (Hozier), Firework (Katy Perry), We Are Young (Fun), Wake Me Up (Avicii), and Wrecking Ball (Miley Cyrus).
This Chorus Form showcases the Title/Hook with maximum utilization of the Primacy and Recency Effect. The Title/Hook is the first AND last thing a listener hears. This Chorus Form exhibits self possession (but can also reveal a hollowness or emptiness). There’s a circular aspect to this form, that when all is said and done, you come back to the original idea/thought. Imagine using it to highlight that someone is the first and last person thought of in a day.
Examples of the T~~T Chorus Form are: On Top of the World (Imagine Dragons), Feels So Close (Calvin Harris), and Coming Home (Diddy-Dirty Money).
The Godzilla of all Chorus Forms! The TTTT can be flashy, ostentatious, and extravagant. It can also demonstrate strong conviction and dedication. This Chorus Form is deployed in every genre and every style more than the other Chorus Forms combined. Ironically, I find most songwriters are apprehensive about the TTTT. Are you cheating by repeating the same lines over and over? In the spirit of full disclosure, I was on the haters side until after I analyzed hundreds and hundreds of songs and surprisingly discovered the sheer number of my favorite songs that utilized this chorus form. I was genuinely shocked. Now, I completely embrace it!
Examples of the TTTT Chorus Form are: We Will Rock You (Queen), Happy (Pharrell Williams), Boom Clap (Charli XCX), Sail (AWOLNATION), and All About the Bass (Meghan Trainor).
So there you have it.
These six Chorus Forms are the most common in popular music. Yes, there are others (particularly: TTT~, T~TT, and TT~T!) but they occur far less (they are still very valid and wonderful to use!).
Which of the Common Chorus Forms should you use? I recommend commandeering the one that most favorably represents the emotional intent of your Title/Hook. This allows you to connect with your song, and ultimately your listeners, on an emotional level.
