What I Actually Do in a Co-Write

Songwriting got sold as a lonely business. Most of the songs I am proudest of had someone else in the room.

July 30, 2026 · 5 min read

I learned music in a church band at thirteen, standing between a bass player twice my age and a drummer who could not read a note, and the first thing I learned was not a chord. It was how to lock in. How to be one useful part of a bigger sound and not the whole show. Most of the songs I am proudest of had someone else in the room when they got written.

Songwriting got sold to us as a lonely business. The lone genius, the candle, the bolt from nowhere. I have never worked that way for long, and I do not think you have to either. A co-write is just two people doing together a job that is hard to do alone. Here is what actually happens in a good one, and how not to make it weird.

What I actually do

1. Show up with one half-idea, not ten

Bring one thing. A verse, a title, a riff, a feeling. Half-finished is perfect, because half-finished leaves the other person somewhere to stand. Ten polished ideas is not generosity, it is a wall. You have not left them any room. Leave them room, the way you leave a drummer room.

2. Say yes before you say but

When someone offers a line, the worst thing you can do is improve it in the first four seconds. Play it. Sing it. Let it be real in the room for a minute before you lay a finger on it. Half the lines I would have killed at first hearing turned out, once I had actually heard them, to be the best thing in the song.

3. Let the other person be wrong out loud

The good accidents live in the bad ideas said at full volume. A room where nobody will risk a duff line is a room where nobody writes anything. Make it safe to be wrong, loudly, and then mine the wreckage. That is where the surprises are.

4. Serve the song, not your corner of it

The question is never "is this my bit." The question is "what does the song want." If their chorus beats your chorus, theirs goes in, and you are glad, because you are both working for the song and not for the credit. You are the bass player at thirteen again, holding the thing down so somebody else can fly.

5. Leave the room better than you found it

Vince, the bandleader who hired me at nineteen, had one line he repeated until it stuck: leave every room better than you found it. Send the rough recording that evening. Say the thing you liked, out loud, before you leave. A co-write is a relationship, and the next one starts the second this one ends.

The question is never "is this my bit." The question is "what does the song want."

When the room goes quiet

I have a friend, Hannah, who lives in another city. When either of us is stuck we send the other a rough, embarrassing voice memo, no notes and no apology. She sent me one at half eleven on Tuesday and I sent one straight back. That is a co-write too, just stretched across a phone and a few hundred miles. Someone waiting on the other end is half the reason a song ever gets finished.

And when two of you are circling and nothing is catching, it helps to have a third thing throw a curveball in. CollisionLab slams two unrelated ideas together on purpose, which is exactly the move a good co-writer makes when the room goes silent. (Once you have the bones down between you, a quick demo is how you find out what you actually wrote.)

Need a third voice in the room?

CollisionLab throws two unrelated ideas together so you have something to react to. The fastest way to unstick a co-write that has gone quiet.

Open CollisionLab

You do not have to write alone. Most people who think they are bad at finishing songs are just trying to do, by themselves, a job that was always meant to have two pairs of hands.

Bring half an idea. Say yes first. Leave the room better.
