AI rap generator: from a beat you tap to a verse that sits in the pocket

Three ways to start a rap song in Midhull

Whichever you choose, set the vocal to rap. Midhull's vocal types include rap alongside female, male, duet, group, choir and whisper, and the song structure has a dedicated rap section, so a sung hook with rapped verses is a normal request.

Bar maths: how many words fit

A bar in 4/4 is four beats. At a given tempo, the length of a bar is 240 divided by the BPM, in seconds.

The syllable ranges are our working rule of thumb, not a law; dense writers go far above them. The point is consistency: a bar with 22 syllables next to one with 8 forces the vocal to rush and then wait, which is the most common reason AI rap sounds off.

Write bars that land

1. One line, one bar. Write each bar on its own line, so the engine reads your phrasing.
2. Put the rhyme on beat four. End rhymes land on the last strong beat. Add internal rhymes inside the line once the end rhymes work.
3. Use multisyllable rhymes for the punchlines. "Basement / patience / statement" carries further than "cat / hat".
4. Count syllables and keep the bars within a few of each other.
5. Leave air. Two short bars in a row give the verse a breath and make the next bar hit harder.
6. Make the hook singable. A sung hook between rapped verses is the classic shape; tag it [Chorus].

Here is a 16 bar verse and a hook we wrote for a 90 BPM boom bap track. Prompt: "Boom bap, dusty drums, vinyl crackle, jazzy piano loop, confident male rap, sung female hook."

[Rap]
Started in a basement with a laptop and a fan
Mum said get a job, I said I've got a plan
Wrote it on receipts from the corner shop till
Every other kid had a dream, I had a drill
Up at six for the bus, back at ten for the beat
Two hours sleep, now I'm writing on my feet
Neighbours banging on the wall in the middle of a take
Turned it into kick drums, every knock that they make
Teacher said I talk too much, now I talk in bars
Same mouth, new map, now it's pointing at the stars
Patience is a habit, not a thing you're born with
I learned it in the queue that the whole estate was formed in
Every no I heard is a brick in the wall
Now the wall is a stage and the stage is all
So if you hear me knocking, it's the sound of the floor
Built it out of nothing, now I'm building some more

[Chorus]
From the basement to the light
Every wrong turn made it right
Turn it up, let the whole block know
From the basement, here we go

Most bars run 10 to 13 syllables, which sits well at 90 BPM. Rhymes land at the line ends (fan, plan; till, drill; beat, feet), with internal echoes in the second half (talk too much, talk in bars). If you would rather not write it yourself, Describe it writes the bars from your subject, and you can rewrite any line afterwards.

Fix one bar, keep the verse

Studio tools open up as you make songs and level up: rewriting and re singing a line are there from your first song, key and tempo open at level 3, regenerating a section and adding a bridge at level 5, swapping an instrument at level 8 and stem export at level 10. Extending a song, changing the vocal style, making it acoustic and remixing into another genre are open from the start.

From level 10, stems export as drums, bass, keys and lead, so you can take the beat into another app and record over it yourself.

What Midhull will not do

It will not rap in the voice or the style of a real artist, and it will not write diss tracks about real private people. Steering is by era, region and production: "late 90s east coast boom bap", "UK drill with sliding 808s", "Atlanta trap with triplet hi hats" are all fine. Your own voice is available once you verify it.
