How to Write a Rap Song

To write a rap song, decide what it says in one sentence, turn that sentence into a title, build an 8-bar hook around the title, outline two 16-bar verses that approach the idea from different sides, then write the bars and edit them aloud. The outline is the step most beginners skip, and it is the one that makes a song feel written instead of collected.

A song differs from a verse in one way: it has a centre. Every line either moves toward the hook or sets it up. When you know the centre before you start, the blank page stops being a problem, because each section has a job you can describe.

This guide is about the page. Beats, recording and arrangement are covered separately, so here you only need a loop at your chosen tempo and something to write on. Everything below can be done in a single evening with a notebook, and the drills at the end take about twenty minutes.

Write a single sentence with a subject, a feeling and a change: "I moved cities and I miss my friends more than I expected." That is a song. "Life is hard" is not, because nothing happens in it. If you cannot write the sentence, you are not ready to write bars.

Decide who is speaking and to whom. A song addressed to "you", one specific person, usually has more force than one addressed to everyone. Decide the tense as well, and stay in it. Write three candidate sentences and choose the one you could talk about for ten minutes.

Circle the two to five words in your sentence that carry the most weight. That is your working title, and it belongs in the hook, ideally as the first or last words of the line. A listener should be able to guess the title after one chorus.

Hooks are simpler than verses on purpose: fewer syllables, longer notes, more repetition. A dependable pattern is the title line, a response line, the title line again, and a twist. Write four versions of the hook, each in under three minutes, then say them all over the loop and keep the one that is easiest to remember.

Split each 16-bar verse into four blocks of four bars and write one plain sentence saying what each block covers. Eight sentences give you the whole song in prose. Now you can see if verse two repeats verse one, or if the story jumps.

A simple arc for a first song looks like this.

• Verse one, bars 1 to 4: where and when, with one image the listener can see
• Verse one, bars 5 to 16: the situation and what is wrong or wanted
• Verse two, bars 1 to 8: the turn, something changes or is decided
• Verse two, bars 9 to 16: where that leaves you, ending on a line that hands over to the hook

If the hook and verses have the same rhythm and density, the song blurs. Give the verses 11 to 14 syllables a bar and the hook 6 to 10. Change the rhyme scheme as well: couplets in the verse and one repeated sound in the hook, or the reverse.

Place a small event every four bars in the verses: a pause, a repeated word, a switch from end rhyme to internal rhyme. These keep attention without a new idea. Mark on your outline where each one goes, then check the finished verse still has them.

First pass, sense: read the lyrics as prose and delete any bar that does not serve the one-sentence idea, however clever. Second pass, sound: rap it over the loop and mark every place you stumble or run out of beat. Rewrite those bars, usually by cutting a word.

Third pass, breath: perform the whole song without stopping and note where you gasp. Shorten the bar before each gasp by one or two syllables. Leave a day between passes when you can. Fresh ears catch weak lines that tired ones excuse. Finish by reading the title, then the hook, then the last bar, and check they agree.

The joins between sections decide whether a song feels like one piece. Listeners rarely notice a good transition, and they always notice a bad one. The last two bars of each verse should lean toward the hook: raise a question the chorus answers, or end on a word that rhymes with the title phrase. The first bar after a hook should reset the scene quickly, with a time, a place or a name.

A pre-hook is a 2 or 4 bar passage before the chorus with a simpler rhythm than the verse, used to build anticipation. A bridge is 4 to 8 bars near the end that steps away from both verse and hook: a new angle, a quieter delivery, sometimes spoken. Neither is required. Add one only if the song feels flat on the third hook. To test your joins, read just the last line of each verse followed by the first line of the hook. If the pair makes sense alone, the transition works. Rewrite any pair that does not.

• Verse ending: a question or an unfinished thought
• Pre-hook: 2 to 4 bars, fewer words, rising energy
• Bridge: 4 to 8 bars, new angle, placed before the last hook

Both orders work, and each has a cost. Choosing a beat first gives you a tempo, a mood and a bar length before you write a word, so lines arrive already shaped to fit. The cost is that the beat can decide the subject for you. Writing words first protects the idea, and you then have to trim or stretch lines when the music arrives.

For a first song, pick the beat early: after the one-sentence idea and before the hook. Look for a tempo you can talk over comfortably, usually 85 to 100 BPM for a boom bap feel, or 130 to 150 counted at half speed for trap. If you have no instrumental yet, a drum pattern at the right tempo in the rap beat maker is enough to write to.

Then find your pocket, the rhythmic space where your voice sits comfortably against the drums. Loop 4 bars and mumble nonsense syllables for two minutes, trying a few different rhythms, and record it on your phone. The rhythm you fall into most easily is your pocket for this song, and the hook should use it.

A bar is a unit of time: four beats of the instrumental. A line is a unit of paper. They usually match, one line per bar, but not always. A long sentence can run across two bars, and a short phrase can fill half of one. When a verse is called 16 bars, that means 64 beats of music, whatever the page looks like.

This matters when the sections are assembled. If your hook is 8 lines and each line takes only two beats, you have a 4-bar hook, and it will be over before the listener settles in. Count along with the loop while you rap: "1, 2, 3, 4" for bar one, "2, 2, 3, 4" for bar two, and so on. Write the bar number in the margin wherever a new bar starts.

Use the snare as your anchor. In most rap beats it hits on beats 2 and 4, and the rhyme word usually lands on or near beat 4. Take the hook you wrote and mark where beat 4 falls in each bar. If the rhyme words sit there, the section will feel locked. If they drift, move a word.

• One line, one bar: Boxes in the hall and the kettle in a bag
• One line, two bars: I said I'd come and visit when the weather turned, and then the weather turned and I was working
• Two lines, one bar: Train's late. / Phone's dead.

Stopping mid-line to hunt for a rhyme breaks concentration and tends to bend the sentence toward whatever word turns up. A rhyme bank separates the two jobs. Before drafting the verses, collect sounds. While drafting, choose from them.

Take the 6 to 8 words that matter most to the song: the title words and the main nouns from your outline. Put each at the top of a column. Under it, list 8 to 10 rhymes and near rhymes, including two-word phrases. The rhyme finder gives perfect and near rhymes grouped by syllable count, which fills a column in under a minute.

The bank is a menu, not a script. A word belongs in a bar only if it says something the song needs, so expect to use about a quarter of what you collect. Build the bank for your current song now, and star the three words in each column that suit the subject.

• Chat: back, that, flat, unpacked, came back, fall flat, map, laugh
• Home: phone, alone, known, tone, on my own, ringtone, postcode
• Miss: this, list, exist, dismiss, insist, reminisce

The standard layout is a starting point, not a rule. Structure decides when the listener first hears the hook and how long they wait for it to return. The three layouts in the list cover most first songs. Lengths assume 90 BPM, where 8 bars last about 21 seconds.

Pick by asking where the strongest material is. If the hook is the reason the song exists, let it open. If the verses carry a story, start with the first scene. If you have one and a half good verses, go short instead of padding. A song that ends early gets replayed, and one that drags does not.

Write your chosen layout as a column of section names with bar counts down the left side of a page, and fill in what you already have.

• Hook first: intro 4, hook 8, verse 16, hook 8, verse 16, hook 8, outro 4. That is 64 bars, about 2:50. Suits a song whose chorus is its strongest part.
• Verse first: verse 16, hook 8, verse 16, hook 8, bridge 8, hook 8. Also 64 bars. Suits a story that needs setting up before the chorus makes sense.
• Short form: hook 8, verse 12, hook 8, verse 12, hook 8. That is 48 bars, about 2:10. Suits a simple idea that would wear thin over three minutes.

The page hides problems that a recording reveals in seconds. As soon as you have a hook and one verse, record them over the beat on your phone.

Listen back once without the lyrics in front of you and note four things: any word you cannot make out, any place you hear yourself rush, any bar where your energy drops, and whether you can still recall the hook an hour later. Each note points to a specific fix: a clearer word, a shorter bar, a stronger line, a simpler hook.

Set a limit on revising. A workable first session is 50 minutes: 5 for the idea and title, 10 for the hook, 20 for a rough first verse, 5 to record, and 10 to listen and fix the two worst bars. Stop there. Learning how to write a rap song is mostly a matter of finishing rough ones. Book those 50 minutes for a specific day this week.
