Songwriting vs. Master Copyrights

By PMApub Academy · Last reviewed 2026-10-13 · About 7 min read

The two copyrights in every song

The composition copyright (often called the songwriting or publishing copyright) covers the underlying musical work. That includes the melody, the lyrics, and the way the song is arranged, as long as those elements are original. A composition can exist on paper, in a voice memo, or in a recording. It does not depend on any single performance of the song.

The sound recording copyright (usually called the master) covers one particular recorded performance of that composition. It is the WAV or MP3 file, along with the creative choices that went into capturing and producing that sound. If you record the same song twice, you have created two different masters but still only one composition.

A helpful shortcut: the composition controls the song itself, and the master controls the sound of that particular recording.

Who owns what by default

Copyright generally exists from the moment an original work is fixed in a tangible form, such as written down or recorded. You do not need to file anything for the right to exist, although registration with the U.S. Copyright Office is a separate, optional step. For U.S. works it is generally needed before you can sue to enforce your rights, and registering promptly can preserve access to remedies such as statutory damages and attorney's fees. If you own both the song and the recording, they can often be registered together on one application, which the Copyright Office explains in its circulars.

Traditionally, songwriters and their music publishers own compositions, while recording artists and record labels own masters. For an independent artist who writes and records their own music without a label or publishing deal, you typically start out owning both. That is a strong position, but it only stays strong if you keep track of what you have agreed to along the way.

Ownership can get more complicated when other people contribute. A co-writer may share the composition. A producer, a hired musician, or a studio may have terms about the master. Written agreements are the cleanest way to settle this before a song is released.

Why the two copyrights earn money differently

Because the rights are separate, different organizations collect the money tied to each one. In the United States, the general picture looks like this:

• Composition income: public performance royalties are collected by performing rights organizations such as ASCAP, BMI, SESAC, and GMR. Mechanical royalties for eligible U.S. digital streams and downloads are handled by The MLC (Mechanical Licensing Collective) under the blanket license, and sync licenses for film, TV, and ads are negotiated for the composition.
• Master income: streaming and download revenue flows through your distributor or label. Digital performance royalties for the recording on non-interactive services, such as satellite and internet radio, are collected by SoundExchange. Sync licenses for the master are negotiated separately.

This is why an artist can be paid by their distributor and still be missing money from a PRO or The MLC. Each stream of a song generates value on both sides, but you only collect on a side if the right registrations are in place.

A real-world example: Maya's single

Maya writes a song alone in her bedroom and records it with a producer she pays a flat fee. She owns the composition because she wrote it. Assuming her producer agreement says she owns the finished recording, she also owns the master.

A filmmaker emails and asks to use the song in a short film. Maya needs to ask: do they want the song, the recording, or both? A sync license for the composition lets them use the song. A master use license lets them use her specific recording. If they want to use Maya's recording, they need both permissions. If they plan to hire a band to re-record the song, they would only need the composition license.

Because Maya sees these as two assets, she can price and negotiate each one separately instead of giving away everything in a single vague yes.

A simple system for keeping your catalog organized

You do not need complicated software. A spreadsheet is enough to begin with. Create one row per song and track the following:

1. Song title and the date it was finished.
2. Every songwriter's legal name and their percentage of the composition.
3. Who owns the master and what agreements apply to it.
4. Where the composition is registered, such as your PRO and The MLC.
5. Where the recording is distributed and its identifying codes.
6. Any licenses you have granted, to whom, and for how long.

PMApub offers a Music Monetization Plan template that gives you a structure to organize this kind of information. Whatever tool you use, the habit matters more than the format. When any legal question about ownership or contracts comes up, a qualified music attorney can review your specific situation, and an accountant can help with how income is reported.

For labels, managers, and teams

When you run a label or manage several artists, the two-copyright split stops being a concept and becomes a filing system. Every release has at least two ownership questions, and the answers are rarely the same for every artist on your roster.

Start with paper. A recording agreement should say who owns each master, what license the label receives if the artist keeps ownership, and what happens at the end of the term. A separate split sheet for every song should name each writer, their percentage of the composition, and their performing rights organization. Do not treat the recording agreement as a substitute for it, because owning or controlling a master does not give you the composition.

Producers, mixers, and session players add layers. Get written terms for any royalty or credit they expect, and confirm whether anything is sampled or interpolated, since a sample usually involves permission for both the recording and the underlying song.

For royalty accounting, keep master income and composition income in separate ledgers. Label statements to artists normally cover master revenue under the contract, while songwriting income may flow to the writers, their publishers, or an administrator through other channels. Mixing them hides errors.

Finally, treat catalog hygiene as routine. Keep one master sheet with each song, its writers, splits, master owner, ISRC, registrations, and licenses granted. Review it before every release and before any audit, sale, or licensing request. Have an attorney review contracts that assign or exclusively license rights.

Common mistakes to avoid

• Assuming a recording agreement also gives the label rights in the composition. It does not unless the contract clearly says so.
• Releasing before split sheets are signed. Disagreements about percentages are far harder to resolve after a song starts earning.
• Dividing splits by who did the most work in the studio rather than recording what the writers actually agreed. Master and composition ownership can be divided differently.
• Treating copyright registration as required for ownership. Ownership exists from fixation; registration is a separate step that matters mainly for enforcement.
• Using someone else's recording or song as a sample without asking about both the master and the composition.
• Signing a broad assignment of copyrights without understanding its length, territory, and what you get in return.
• Assuming a producer who was paid a flat fee has no claim, with no written agreement saying so.
• Releasing a cover and assuming the new recording makes the song yours. You may own the new master, but the composition still belongs to its writers.

Action checklist

1. List every song you own or control and note who wrote it.
2. Write down who owns each master and which agreement says so.
3. Create a signed split sheet for every co-written song.
4. Confirm in writing what any producer, mixer, or session player is owed.
5. Check whether any song contains a sample or an interpolation and get permission for each side.
6. Decide where each song will be registered, including a PRO and The MLC for the composition.
7. Consider registering important works with the U.S. Copyright Office, using the combined recording and song option when you control both.
8. Record every license you grant, with the licensee, scope, territory, and term.
9. Keep one catalog sheet and update it with every release.
10. Have a music attorney review any agreement that transfers or exclusively licenses a copyright.
