Song structure is the order of sections in a song: intro, verse, chorus, bridge and so on. Most popular songs repeat a few sections in a predictable order. That repetition is what makes a song easy to follow and its chorus easy to remember.
The sections and what each one does
| Section | What it does |
|---|---|
| Intro | Sets the mood and tempo before the vocal starts. Often short. |
| Verse | Tells the story. The music repeats from verse to verse, but the lyrics change. |
| Pre-chorus | A short build that lifts the energy into the chorus. |
| Chorus | The main idea and the catchiest part. Lyrics and music usually stay the same each time. |
| Post-chorus | A short hook after the chorus, often a repeated word or melody. |
| Bridge | New chords or melody, usually once, to give contrast before the last chorus. |
| Outro | Brings the song to an end, by fading out, repeating the chorus or a final hit. |
Verse vs chorus
The easiest way to tell them apart: the chorus has the same words each time and usually contains the song’s title. The verse has new words each time. The chorus is normally bigger: more instruments, higher melody, more energy.
Common song structures
Verse–chorus (pop and rock)
Intro – Verse – Chorus – Verse – Chorus – Bridge – Chorus – Outro
The most common layout in pop and rock. The bridge gives a break from the verse and chorus so the final chorus feels fresh.
With a pre-chorus
Intro – Verse – Pre-chorus – Chorus – Verse – Pre-chorus – Chorus – Bridge – Chorus – Outro
The pre-chorus adds a step of build-up, so the chorus lands harder.
AABA (32-bar form)
Four 8-bar sections: A – A – B – A. The A section carries the main melody and the B section is a contrasting bridge. Many older pop songs and jazz standards use it.
12-bar blues
One 12-bar chord pattern repeated, with new lyrics each time. See the chords in our guide to common chord progressions.
Hip hop
Intro – Hook – Verse – Hook – Verse – Hook – Outro
The chorus is usually called the hook. Rap verses are often 16 bars long and hooks often 8 bars, though this varies a lot.
Electronic and dance music
Intro – Build-up – Drop – Breakdown – Build-up – Drop – Outro
The drop takes the place of the chorus. Intros and outros are often long and steady so DJs can mix in and out of the track. If you DJ, the Camelot wheel helps you pick tracks in compatible keys.
Counting bars
Sections are usually measured in bars, and most are 4, 8 or 16 bars long. In 4/4 time, one bar is four beats; see time signatures explained. At a given tempo you can work out how long a section lasts:
Seconds = bars × beats per bar × 60 ÷ BPM.
For example, an 8-bar chorus in 4/4 at 120 BPM lasts 8 × 4 × 60 ÷ 120 = 16 seconds. Find a song’s tempo with our BPM Tapper.
Mapping a structure in your DAW
- Set the tempo and time signature first, so the bar grid is correct.
- Use markers or coloured regions to label each section along the timeline. Most DAWs have arrangement markers.
- Write the chorus first if you are stuck. It is the part people remember, and the verse can be built to lead into it.
- Copy a song you like. Drag a reference track into your DAW, mark where each section starts, and use those lengths as a template.
Frequently asked questions
What is the most common song structure?
Verse – Chorus – Verse – Chorus – Bridge – Chorus, usually with an intro and outro. Most pop and rock songs use it or something close to it.
What is the difference between a bridge and a pre-chorus?
A pre-chorus comes before every chorus and builds into it. A bridge usually appears once, late in the song, and brings new chords or melody for contrast.
How long is a verse?
Commonly 8 or 16 bars, though there is no fixed rule. Rap verses are often 16 bars.
What is a hook?
The catchiest part of a song. In hip hop, “hook” usually means the chorus. In other styles it can be any short, repeated melody or phrase.
