How to write a song with a looper

Updated 2026-08-09

Looping changes songwriting because you stop imagining the arrangement and start hearing it. Record the chords, and the bass line you were unsure about becomes obviously right or obviously wrong within one pass. Most of songwriting is deciding, and a looper makes the decisions audible.

Start with the part that repeats

Songs are built on something that comes back. Record that thing first — the progression, the riff, the groove — and let it play while you work out what goes over it.

This is the opposite of writing on paper, where you decide the melody and then harmonise it. Here the bed exists, and the melody has to survive contact with it.

A working method

1. Loop four bars of the progression. Do not polish it. It is scaffolding.
2. Sing nonsense over it. Melodies arrive faster without lyrics in the way.
3. Keep the one thing you sang twice. If you repeated it without meaning to, it is memorable.
4. Add the bass. Now the progression is defined and you will hear whether the melody still works.
5. Take something away. Mute a layer. Songs usually improve.
6. Record the whole thing before you forget the arrangement you just found.

Use mute as an arranging tool

The most underused feature in any looper is the mute button. Build four layers, then perform the arrangement by muting and unmuting — bass alone for the verse, everything for the chorus, chords only for the bridge.

You are not writing a part; you are writing a structure. It takes two minutes and tells you whether the song has any dynamics before you spend a weekend recording it properly.

Keep the sketch

Export the loop while it is fresh — .mp3, .m4a, .wav and .caf all work — or publish it as a web page and send it to whoever you write with. The sketch that survives is the one you can play to someone, not the one you meant to record later.
