Masters and Publishing: The Two Halves Every Artist Should Understand

Two property rights, one recording

Every song you hear on Spotify or any other streaming service is the meeting place of two distinct property rights.

The first is the composition, also called the musical work. This is the song itself: the melody, harmony, and lyric as written. It exists before any recording happens and would still exist if no one ever pressed record. The U.S. Copyright Office's Circular 56A on copyright registration for musical compositions describes this work as the underlying composition that any number of artists could record.

The second is the sound recording, often called the master. This is the specific recorded performance of that composition. The U.S. Copyright Office's Circular 56 on copyright registration for sound recordings describes this as a separate work, with its own copyright, fixed in tangible form when the recording is made.

The Copyright Office's choice to register these as two distinct works is the legal foundation of every royalty conversation that follows. They are owned separately. They are licensed separately. They are collected separately. They can be split off, sold, retained, or assigned independently of each other.

For a full canonical entry, the FTSMusic Definitions page carries short citation-ready forms of both terms.

Who owns the composition

The composition is created by the songwriter, and the songwriter is the initial owner. In modern practice, most commercially released songs are co-written, which means the composition is jointly owned by all credited writers in the shares they agree to before or at the session.

Songwriters can administer their own publishing or assign some or all of their interest to a publisher. A publishing deal does not change who wrote the song. It does change who controls the income, the licensing, and the administrative work involved in collecting that income.

The publishing rights split is usually expressed as the writer's share and the publisher's share. In a standard structure each is approximately half of the income, although this varies by deal type. A self-published songwriter who has not assigned any publishing interest collects both halves.

Who owns the master

The master is owned by whoever paid for the recording, unless a written agreement says otherwise. This is the principle that drives the entire ownership conversation around recording contracts.

In a traditional recording deal, the label funds the recording and acquires the master in exchange. The artist then earns royalties on master income according to the contract terms. In an independent release where the artist or their company funded the recording, the master is typically retained by the artist or their company.

Master ownership controls four important decisions: reproduction (physical and digital copies), distribution, public performance of the recording, and licensing for sync placements. Each of those decisions generates its own income stream and its own contractual surface.

How composition royalties flow

The composition generates two main streams of royalty income in the United States, plus a third stream for sync placements.

Performance royalties are paid when the composition is performed publicly. This includes streaming services, terrestrial radio, satellite radio, and live venues. They are collected by performing rights organizations. The ASCAP help page on royalties and payment explains that ASCAP collects performance royalties from licensees and distributes them to its songwriter and publisher members on a quarterly basis. BMI, SESAC, and GMR follow comparable structures.

Mechanical royalties are paid when the composition is reproduced. In the streaming era this includes every U.S. on-demand stream from a licensed digital service. The Mechanical Licensing Collective's "About" page describes the MLC as the U.S. nonprofit designated under the 2018 Music Modernization Act to administer the blanket mechanical license, collect mechanical royalties from licensed digital services, and pay them to songwriters and publishers.

Sync royalties are paid when a composition is paired with visual media. They are negotiated directly with the rights holder and they are not administered through a PRO or the MLC. A single sync license usually pays the composition side and the master side separately to their respective owners.

How master royalties flow

The master generates its own set of streams.

Master royalties from on-demand streaming services are paid by the platforms to whoever holds the master, typically through the distributor that delivered the recording. These payments are negotiated as a share of the platform's user-centric or pro rata pool, not as a fixed rate per stream.

Master royalties from non-interactive digital performance, which includes services like SiriusXM and webcasters, are collected and paid in the United States by SoundExchange. The SoundExchange "About" page describes the organization as the U.S. designee for the statutory royalty paid by non-interactive digital services to performers and copyright owners of sound recordings.

Master royalties from physical sales, downloads, sync, and certain other uses are paid directly to the master owner under the relevant license. Outside the United States, neighboring rights organizations collect comparable income for sound recording performance, and an independent artist who has not registered with the right foreign collection societies will leave that money on the table.

Why the split matters for an independent career

The split between composition and master is the foundation of every ownership decision an independent artist makes.

If an artist writes their own songs and funds their own recordings, they hold both halves by default. That is the operator-artist posture: control of the composition through self-published rights administration, control of the master through independent ownership. Income from both flows to the artist or their business directly, and licensing decisions remain in their hands.

If an artist signs a traditional label deal, the master typically transfers to the label in exchange for funding and marketing. The composition stays with the songwriter, although a publishing deal can be signed separately. The artist may earn royalties on master income, but they are no longer the master owner. That is a deal you can choose. It is not a deal you have to accept.

If an artist signs a publishing deal, the composition side is partially assigned. The master side is unaffected by that decision. A self-published songwriter who signs a label deal is in a different position than a fully-signed writer-artist; the two halves of their rights estate are doing different things.

The four most common confusions

Several misunderstandings repeat across operator conversations.

The first is that "owning the song" means one thing. It does not. Owning the composition and owning the master are two different states, and most working artists hold a different position on each.

The second is that the PRO covers everything on the composition side. It does not. PROs collect performance royalties. Mechanical royalties go through the MLC in the United States. Sync income is direct.

The third is that SoundExchange collects everything on the master side. It does not. SoundExchange collects U.S. non-interactive digital performance royalties for the master. On-demand stream master royalties come through distribution.

The fourth is that a sync placement is a single payment. It is not. A sync placement typically pays the composition owner (via the publishing side) and the master owner (via the master side) as two separate licenses. An artist who owns both halves collects both checks.

What an independent artist should know this week

If you write and record your own songs, you hold both halves until you assign them. Confirm three things while that is true.

First, that you are registered with the Mechanical Licensing Collective as a self-administered publisher or through your distributor's MLC link, so that U.S. mechanical royalties on your compositions are collected.

Second, that you are affiliated with a PRO (ASCAP, BMI, SESAC, or GMR) so that U.S. and foreign performance royalties on your compositions are collected.

Third, that your master royalties from on-demand streaming flow through a distributor you control, and that you are registered with SoundExchange on the master side so that U.S. non-interactive digital performance royalties on your recordings are collected.

Those three confirmations cover most of the routine income an independent operator earns from a catalog. They do not cover sync, which is direct, and they do not cover foreign neighboring rights, which is a separate piece of work.

Key takeaways

• The composition is the song. The master is the recording. The two are separate works under U.S. copyright law.
• Composition royalties flow through PROs and the MLC. Master royalties flow through distribution and SoundExchange.
• Most modern deals involve the assignment of one or both rights in exchange for advances or services.
• An independent artist who writes and records can hold both halves until they choose otherwise.

The split between the master and the composition is not a technicality. It is the structure of the working career.
