If you want to know how to write a rap hook, start with its job: be the part people remember after one listen. A verse can take its time; an 8 bar hook gets roughly 20 to 30 seconds to stick, depending on the tempo. This guide is about rap hooks specifically: how long they are, the four main styles, where they sit in a song and how to test one before you record, with original examples throughout.
Hook or chorus: what rappers mean
In rap, both words name the same part: the section that comes back between verses. Hook is what rappers and producers say in the studio; chorus is the general songwriting word. So whether you search how to write a chorus for a rap song or how to write a hook for a rap song, you are asking the same thing. The fine print: in songwriting theory, the hook is the catchiest phrase and the chorus is the whole repeated section, so a chorus can contain a hook. On NKSounds beat pages the part is simply called Hook.
How many bars is a hook?
The usual answers to how many bars in a chorus:
8 bars
The standard. Room for an idea, short enough to repeat.
4 bars
Short and punchy, often sung twice to fill 8.
The double hook, 16 bars
The 8 bar hook played twice, common to open or close a song.
Eight bars is 32 beats: about 21 seconds at 90 BPM (32 times 60, divided by the BPM). On a 140 BPM trap beat played in half time, rappers count at the felt tempo, so each line covers two bars of the beat and an 8 bar hook lasts about 27 seconds, or 16 bars in your recording software. Either way it is short enough for a listener to hear the hook three times in one play of the song, which is exactly the point. A 4 bar hook sung twice also lets you change the last line the second time round, a small surprise that keeps the repeat fresh.
Four kinds of rap hooks
The chant
A short phrase rapped or shouted in rhythm, often doubled by several voices. Made for bouncy trap beats and for crowds.
The sung melody
A melodic line over the chords. The most memorable kind when it works, and the hardest to write.
The flow switch
The same rapping voice as the verse, but a different rhythm (slower, triplets, more space), so the hook stands out without a single sung note.
The ad-lib hook
A sparse line, with ad-libs and repeated sounds doing most of the work.
The flow switch is the easiest to try first. If your verse runs on quick sixteenth notes, a hook that drops to four or five words per bar, each one landing squarely on a beat, will stand out even in the same voice. An ad-lib hook can be as simple as one line said twice, with short shouts answering it in the gaps.
A 4 bar chant hook written for this guide, one rhyme sound all the way through (AAAA):
- Still awake, still awake (A)
- Whole town sleeping and I'm still awake (A)
- Every move I make is a move I gotta make (A)
- Whole town sleeping and I'm still awake (A)
Three of the four bars repeat almost word for word. On paper that looks lazy; on a beat, it is what makes people sing along by the second hook.
Write the hook first, or pull it out of your verse
Should you write the hook first? Often, yes. The hook carries the title and the point of the song; once you have it, every verse has a target. But there is a second route, and it answers how to write a chorus from a verse: write the verse, then find the one line that sums it up. Shorten it, repeat it, give it a new rhythm.
Say your verse contains "I kept the lights on with money I didn't have". Cut it down to "Kept the lights on", repeat it, add one line on the same vowel sound, and you have a hook that grew out of the story instead of being bolted on.
A third route works well when you are stuck: mumble over the beat for a few minutes with no plan, record all of it, then listen back for a melody or a phrase that keeps coming back. That repeated phrase is often your hook before you even know what the song is about. The guide on how to write a rap verse covers the other side of the song.
What makes a rap hook catchy
Whether you call it how to write a catchy rap hook or how to make a catchy rap hook, the same five things do the work:
- Repetition: the title line at least twice in 8 bars.
- Short words: one or two syllables, easy to shout back.
- One rhyme sound, held through the whole hook.
- A title line: the hook names the song, or the song is named after the hook.
- Space: fewer words than the verse, with gaps for the beat's melody and your ad-libs.
A before and after. Before: "I've been working hard every single day so I can finally get away from here". Too long, and nothing repeats. After:
- Every day, every day (A)
- One more step and I'm on my way (A)
Same idea, half the words, and a line people can sing back on the second listen. That is most of how to write a good rap hook: say less, repeat more.
And the mistakes that sink a hook most often:
- A new idea on every line, so nothing sticks.
- More words than the verse.
- Complex multis that are fun to write and impossible to sing along to.
- A different rhyme sound on every bar.
Can't sing? Melodic hooks for rappers
- Talk-sing: pick two or three notes from the beat's melody and stay on them.
- Follow the beat: hum the main melody of the beat, then put words on that line.
- Stay in your range: check the key on the beat page. If the melody sits too high, take it an octave lower or switch to a chant.
- Stack takes: record the hook two or three times and layer them. Doubles hide a lot.
- Pitch correction can come later, in the mix, but write a line that works without it.
- Let the beat sing: choose a beat whose melody already sounds like a hook, and rap a short rhythmic line in its gaps.
Melodic hooks come easiest on beats with clear chords and space around them, like melodic rap beats and R&B.
Where the hook goes on a real beat
Two layouts cover most songs. Hook first: after a short intro, the song opens on the hook, so listeners hear the catchiest part before they have time to skip. Verse first: the classic, where the verse sets the mood and the hook pays it off. A short pre-hook of 2 or 4 bars before each hook builds tension, often where the beat drops out.
On a 140 BPM beat played in half time, a hook-first layout could run like this: a short intro of 4 bars of the beat, from 0:00 to 0:07; the hook, 8 lines, from 0:07 to 0:34; then the first verse, 16 lines, from 0:34 to 1:29. The hook is playing before the 10 second mark, which is the whole point of the layout.
Every NKSounds beat page has a Which structure? section with these options for that beat (Hook first, Verse first, No hook, With pre-hook), the timecode where each hook starts and a button to play from there. More on layouts in rap song structure.
Test your hook on three different beats
A hook that only works on one beat may be leaning on that beat. If you came here wondering how to make a rap hook that holds up, this is the step that tells you:
- Pick three beats from the selection below: one melodic, one bouncy trap, one at a different tempo or key.
- On each page, click Write lyrics, write the hook in the Hook box and use Loop this part.
- Rap or sing it four times in a row on each beat. Note where it feels forced.
- The next morning, sing it without looking. Whatever you forgot gets rewritten.
What to listen for: does the hook still make sense to someone who only hears the hook, not the verses? Does the title line land on a strong beat? Can you say each line in one breath?
Keep the beat where the hook sounded most natural. Writing and listening are free; to record and release the song, take a license (see lease vs exclusive), and the mastering of your song is included with every beat you buy.
