Music Copyright Basics for Songwriters

This article is general information, not legal advice. For guidance on your specific situation, speak with a qualified copyright attorney or your local Performing Rights Organization (PRO).

When people talk about "the copyright" in a song, they're usually talking about two separate things: the composition (the underlying lyrics and melody) and the sound recording (the specific recorded performance of that composition, sometimes called the "master"). These are legally distinct, can be owned by different people, and are registered and licensed separately in most jurisdictions.

Composition copyright generally protects the original creative elements a songwriter contributes — melody, lyrics, harmonic structure, and arrangement. It typically exists automatically the moment a work is fixed in a tangible form (written down or recorded), without needing to file anything first. What often does need to happen, though, is agreeing on who contributed what, and in what proportion — because copyright protects the work, but it doesn't automatically settle who owns which share of it.

That's the gap a split sheet fills. A split sheet is a written, signed record of who contributed to a song and what percentage of the composition each collaborator owns. It doesn't create the underlying copyright — the act of creating the work does that — but it's the practical evidence collaborators, publishers, and PROs rely on to know how royalties should be divided.

Without a split sheet, collaborations tend to default to an even split regardless of actual contribution, or worse, no agreement at all — which is exactly the kind of ambiguity that leads to disputes once a song starts earning money. Getting agreement in writing early, while everyone remembers who did what, is one of the simplest things a group of collaborators can do to protect the relationship as much as the royalties.
