Writing alone is great, but writing with someone else can push your songs further than you’d ever go by yourself. If you’re nervous about your first session, don’t be. This guide covers how to co write a song, from what to bring to how songwriting splits work. It’s part of our main guide on how to write a song for beginners, so if you’re still learning the basics, start there.
In a co-writing session, two or more writers build one song together, usually in two to three hours: someone brings an idea or title, the group writes the chorus first, then the verses, and records a rough demo. Songwriting splits are commonly divided equally among everyone in the room, agreed on that day, and written down on a split sheet.

Co-Writing a Song Meaning
Co-writing simply means two or more people writing one song together and sharing ownership of it. Each co-writer owns a share of the composition (the melody and lyrics), and that share determines how royalties are divided.
Co-writing is standard practice in Nashville, pop, worship and many other genres. Writers often schedule regular sessions with different collaborators each week. A typical room has two or three writers, sometimes with a producer who builds a track while the song is being written.
Why co-write?
- You finish more songs. Another person keeps momentum going.
- You learn faster. You’ll pick up new techniques every session.
- Your songs get better. Ideas get tested in real time.
- You build relationships. Many songwriting careers grow through co-writing networks.

Before the session
- Bring ideas. Have three to five titles, a chorus hook, or a chord progression ready. Our songwriting prompts list can help.
- Know your strengths. Are you the lyric person, the melody person, the guitar player? Say so.
- Bring tools. An instrument, a phone for voice memos, and a notebook or laptop.
- Agree on a time. Most sessions run two to three hours.
During the session
- Chat for a few minutes. Good songs often start from real conversation.
- Pitch ideas. Each writer shares a title or hook. Pick the one that excites the room most.
- Write the chorus first. It’s the heart of the song. See how to write a catchy chorus.
- Write the verses. Decide what story each verse tells.
- Add a bridge if needed.
- Record a work tape. A rough phone recording of the whole song, so nobody forgets it.
- Agree on splits before you leave.
After the session
- Share the work tape and lyrics with everyone.
- Fill in a split sheet and send copies to all writers.
- Register the song with each writer’s PRO, listing every writer and their share. See how to collect songwriting royalties.
Co-Writing Etiquette
These unwritten rules keep sessions friendly and productive.
- Say “yes, and” before “no.” Build on ideas before rejecting them. A bad line can lead to a great one.
- Don’t be afraid to throw out bad ideas. Everyone does. The room needs raw material.
- Leave your ego at the door. The best idea wins, whoever it came from.
- Be on time and present. Phones away unless you’re recording.
- Don’t count lines. Arguing over who wrote what kills creativity.
- Keep the song confidential until everyone agrees on what to do with it.
- Never use an idea from the session in a different song without the other writers’ permission.
Songwriting Splits
Splits decide who owns what percentage of the song. Here are the common approaches.
| Approach | How it works | Pros | Cons |
|---|---|---|---|
| Equal split | Everyone in the room gets the same share (two writers 50/50, three writers 33.33% each) | Simple, avoids arguments, widely used | Doesn’t reflect uneven contributions |
| Contribution-based | Shares reflect who wrote what (e.g. 60/40) | Feels fair for lopsided sessions | Easy to argue about |
| Lyrics/music split | Lyricist and composer each take a share | Works for clear roles | Hard when roles overlap |
| Producer share | A producer who contributes to the song gets a writer share | Recognizes track-building | Must be agreed up front |
Many professional co-writers default to an equal split among everyone who was in the room and contributed, because it keeps relationships healthy and focuses the session on the song. Whatever you decide, agree before you leave and put it in writing.
How to Fill In a Split Sheet
A split sheet is a simple document that records who wrote the song and what share each writer owns. Include:
| Field | Example |
|---|---|
| Song title | “Porch Light” |
| Date written | The session date |
| Writer names (legal) | Full legal names |
| Share of composition | 50% / 50% |
| PRO affiliation | BMI, ASCAP, SESAC or GMR |
| PRO IPI/CAE number | From each writer’s PRO account |
| Publisher (if any) | Publisher name and share |
| Signatures | Every writer signs |
Send a copy to every writer and keep one with your song files. Use the same information when you register the song with your PRO and The MLC.
Step-by-Step: Your First Co-Write
- Find a co-writer. Try local songwriter nights, NSAI chapters, worship teams or online communities.
- Schedule a two- to three-hour session.
- Prepare three ideas each.
- Pick one idea together and start with the chorus.
- Write the verses and bridge.
- Record a work tape on a phone.
- Agree on splits and fill in a split sheet.
- Share files and register the song.

Handling Disagreements in the Room
Even friendly sessions hit snags. Here’s how to keep moving.
When you disagree on a line, try both versions out loud in the melody. Hearing them sung usually settles it. If not, park the line, keep writing, and come back later with fresh ears.
When one writer is dominating, the other can ask a simple question like “Can we try a few more options for this line?” It opens the floor without sounding like criticism.
When the song stalls, go back to the title and the one-sentence idea. Ask what the song is really about. Often the problem is that the verses have drifted from the chorus.
When you don’t love the song, finish it anyway. You’ll learn from it, you’ll keep a good relationship with your co-writer, and sometimes the song you weren’t sure about turns out to be the one people connect with.
What Happens to the Song Afterward?
Once the session is done, agree on next steps together, and if anyone has a publishing deal, check what it requires. Decide who will make a better demo, who will pitch it to artists, and whether anyone plans to release it. If one writer wants to change lyrics later, check with the others first. It’s a shared song, and keeping everyone informed protects the friendship as much as the copyright.
Remote Co-Writing
Video calls make it easy to co-write across cities. A few tips:
- Use a shared document for lyrics so everyone can see changes live.
- Have one person hold the instrument to avoid lag problems.
- Record the call (with everyone’s permission) as your work tape.
- Collaboration apps help. Free tools like BandLab let co-writers work on the same project from different places.
Frequently Asked Questions
How are songwriting splits usually divided?
Many co-writers split equally among everyone who contributed in the room, so two writers get 50% each and three get about 33.33% each. Others split by contribution. Agree before you leave and write it down.
What is a split sheet?
A split sheet is a short signed document that lists the song title, date, each writer’s legal name, PRO and ownership percentage. It prevents disputes and makes registration easy.
What if a co-writer only contributed one line?
That’s exactly why many writers use equal splits: a single line can be the hook that makes the song. If you prefer contribution-based splits, discuss it openly and agree in writing.
Do I need a contract to co-write?
A signed split sheet is the minimum. For bigger projects, publishers or attorneys may use formal agreements. This isn’t legal advice, so talk to a music attorney for anything complex.
How do I find co-writers?
Go to songwriter rounds and open mics, join an NSAI chapter or local songwriter group, connect with your church’s worship team, or join online songwriting communities.
