What is the most common song structure?

The most common structure in pop and R&B is verse, chorus, verse, chorus, bridge, chorus, often with a pre-chorus before each chorus. Songwriters sometimes write it as ABABCB.

What are the parts of a song?

The main parts are the intro, verse, pre-chorus, chorus, post-chorus, bridge and outro. Not every song uses all of them, but almost every pop and R&B song has verses and a chorus.

What is the difference between a verse and a chorus?

A verse tells the story and changes its lyrics each time it comes back. A chorus states the main idea and repeats with the same lyrics, usually with a bigger melody than the verse.

How long should each section of a song be?

Verses and choruses are usually 8 or 16 bars, pre-choruses 4 to 8 bars, and bridges 4 to 8 bars. Those are starting points, not rules, and many songs shorten sections to keep the energy up.

What is AABA song form?

AABA is a form with three verses built on the same melody (A) and one contrasting section (B), often called the bridge or middle eight. It was common in older pop and jazz standards and still shows up in ballads.

Song structure: verse, pre-chorus, chorus, bridge and common forms

Most pop and R&B songs follow a verse, chorus, verse, chorus, bridge, chorus structure, often with a pre-chorus leading into each chorus. Verses tell the story and change every time, the chorus repeats the main idea, and the bridge adds contrast before the last chorus. Knowing what each section does lets you shape a song on purpose instead of by accident.

The parts of a song

Here’s what each section is for, with typical lengths. A bar is one measure of music, usually four beats.

Intro

Sets the mood and introduces the sound of the track. It might be the main instrumental riff, a vocal chop, or a quiet version of the chorus melody.

Typical length: 4 to 8 bars, often shorter in current pop
Job: pull the listener in quickly

Verse

The verse carries the story. It gives details, sets the scene and builds the world of the song. Each verse has new lyrics but usually the same melody.

Typical length: 8 or 16 bars
Job: make the listener care about what the chorus will say

For techniques, read how to write a verse.

Pre-chorus

A short section that builds tension between the verse and the chorus. It often changes chords, rises in melody, or tightens the rhythm so the chorus feels like a release.

Typical length: 4 to 8 bars
Job: create anticipation

Not every song needs one. If your verse already builds naturally into the chorus, you can skip it.

Chorus

The center of the song. It states the main idea, usually includes the title, and repeats with the same lyrics each time. The melody tends to be higher, wider or more energetic than the verse.

Typical length: 8 bars, sometimes 16
Job: be the part people remember and sing back

The guide on how to write a chorus covers hooks and chorus shapes in detail.

Post-chorus

A short section right after the chorus that keeps the energy going. It’s often a chant, a repeated word, a vocal melody without many lyrics, or an instrumental drop. Post-choruses are very common in modern pop and dance-leaning R&B.

Typical length: 4 to 8 bars
Job: add a second hook

Bridge

A contrasting section, usually after the second chorus. It brings a new melody, new chords, or a new angle on the story, then leads back into a final chorus.

Typical length: 4 to 8 bars
Job: break the pattern so the final chorus feels fresh

See how to write a bridge for a step-by-step method.

Outro

The ending. It can repeat the chorus, fade out, strip back to a single instrument, or end with a final line that echoes the intro.

Typical length: 4 to 8 bars, or a repeated chorus

Hook vs chorus

The hook is the catchiest piece of the song, often a single line or phrase. It usually lives inside the chorus but can also be a riff or a post-chorus chant. In hip-hop, the whole chorus is often called the hook.

Common song forms

Songwriters often label sections with letters: A for verse, B for chorus, C for bridge. Here are the forms you’ll hear most.

Verse, chorus (ABAB)

Verse → Chorus → Verse → Chorus

Simple and direct. Common in shorter songs and in genres where the groove carries the track.

Verse, chorus, bridge (ABABCB)

Verse → Chorus → Verse → Chorus → Bridge → Chorus

The most common pop and R&B form. The bridge gives contrast before the last chorus, which often gets extra energy: a key change, more layers, or an ad-libbed vocal.

Verse, pre-chorus, chorus

Verse → Pre-chorus → Chorus → Verse → Pre-chorus → Chorus → Bridge → Chorus

The ABABCB form with a build-up section before every chorus. Very common in big pop songs because it maximizes the payoff of each chorus.

Chorus first

Chorus → Verse → Chorus → Verse → Chorus → Bridge → Chorus

Starts with the hook to grab attention immediately. It suits songs where the chorus is the strongest idea and you don’t want the listener to wait for it.

Verse, chorus, post-chorus

Verse → Pre-chorus → Chorus → Post-chorus → Verse → Pre-chorus → Chorus → Post-chorus → Bridge → Chorus → Post-chorus

Typical of dance pop. The post-chorus acts as a second hook, often with very few words.

AABA

Verse → Verse → Bridge → Verse

An older form common in jazz standards and classic pop, sometimes called 32-bar form when each section is 8 bars. Each A section usually ends with the title line, and the B section (the bridge, or “middle eight”) brings contrast. It still works well for ballads and slow R&B.

Through-composed

No repeating sections. The song moves from one part to the next without returning. Rare in pop, but it shows up in experimental and narrative songs.

Typical lengths at a glance

Section	Common length	Repeats?
Intro	4 to 8 bars	No
Verse	8 or 16 bars	Melody yes, lyrics no
Pre-chorus	4 to 8 bars	Usually same lyrics
Chorus	8 or 16 bars	Yes, same lyrics
Post-chorus	4 to 8 bars	Yes
Bridge	4 to 8 bars	No
Outro	4 to 8 bars	No

These are starting points. Many current songs trim verses to 8 bars or cut the second pre-chorus to keep the song moving.

How to choose a structure

Start with the chorus idea. Once you know the main message, you can decide how much setup it needs.
Decide how much story you have. Lots of detail? Use two full verses. A simple feeling? Shorter verses and a post-chorus might fit better.
Think about energy. Map the song as a curve. Verses lower, chorus higher, bridge different, final chorus highest.
Pick a form as a template. ABABCB with a pre-chorus is a safe default. Change it once you have a draft.
Write with section labels. Label each block on your lyric page so you can see the shape at a glance. If you write in Lyric Studio, labeling sections in the notepad and checking rhyme scheme letters per line makes it easier to keep sections consistent.
Listen back. Record a rough demo. If the chorus arrives too late or the song feels long, cut or move sections.

R&B and pop differences

Pop tends to favor tight, high-energy forms: short intro, early chorus, post-chorus hooks, and a big final chorus.

R&B often gives the verse and the groove more room. You’ll hear longer verses, more vocal improvisation, extended outros with ad-libs, and bridges that work as a slow breakdown rather than a dramatic shift. Pre-choruses are common in both.

Hip-hop and trap use their own conventions, with bar counts at the center. If that’s your style, see rap song structure.

Song structure checklist

You can name the job of each section
The chorus contains the title or main hook
The first chorus arrives within about 45 to 60 seconds
Verse two adds something new instead of repeating verse one
The pre-chorus, if you have one, builds into the chorus
The bridge brings real contrast
The final chorus feels bigger than the first

Structure is a tool, not a rulebook. Once you know the standard forms, breaking them on purpose becomes part of your style. To put a full song together from first idea to final draft, read how to write song lyrics.
