# How to Write Rap Lyrics Over a Beat

Updated June 2026 · by Loopin

Writing raps gets a lot easier when the beat, the bars and the take all live in one place. Here’s a simple, repeatable way to write rap lyrics over a beat — right on your iPhone.

## 1. Pick the beat first

Your lyrics ride the beat, so start there. Drop a type beat or a producer’s loop into [Loopin](/#download) and just listen for a bar or two. Notice where the kick and snare land — that’s the **pocket** your words need to sit in. Writing to silence and forcing it onto a beat later almost never flows as well.

## 2. Lock the key and BPM

Knowing the tempo helps you feel the pocket and pace your syllables; knowing the key matters the second you add a melody or hook. Loopin **auto-detects key and BPM** when you import a beat, so you don’t have to guess.

## 3. Sketch a rhyme scheme

Don’t write a whole verse at once. Lay down the **rhyme scheme** first — where the rhymes land (end rhymes, internal rhymes, multis) and how many bars the pattern runs. A loose 4- or 8-bar skeleton gives the verse shape before you fill in the words.

## 4. Write in time with the loop

Press play, let the beat loop, and write while it runs. This is the whole point of writing *over* a beat instead of in a separate notes app: your bars stay glued to the track and in time. If you freestyle, record a quick take and transcribe the lines you kept — going from **freestyle to written rap** is faster when both live in the same song.

## 5. Punch in and record the take

Record your take right over the beat. Punch in line by line if you need to. Because the take, the lyrics and the beat are all in one Loopin song, you’re never hunting through Voice Memos for “the good one.”

## 6. Keep every version

Rewrote the second verse? Keep both. Loopin saves **every version**, so you can compare and pick the best instead of overwriting your ideas. When the song’s done, run it through [Loopin’s free mastering tool](/mastering) for a streaming-ready master.

This is exactly what the **Loopin app** is built for — a writing space for bedroom rappers and independent artists where the beat and the bars never get separated.
