A performance royalty is paid when music is performed publicly. A mechanical royalty is paid when a musical composition is reproduced and distributed.
Those definitions are short, but they only work if you first separate the properties inside a song.
The composition is the underlying music and lyrics. The recording, or master, is a particular recorded performance. U.S. copyright law gives the owner of a musical work a public-performance right and a reproduction right, while giving sound recordings a narrower performance right for digital audio transmissions (17 U.S.C. § 106).
That creates more than one royalty lane. The composition can generate performance and mechanical royalties. The recording can generate a statutory digital-performance royalty from certain transmissions. The composition’s writer share and publisher share are performance-royalty lanes; they are not labels for the recording side.
If that feels like too many boxes, use one question at a time: which property, and which right?
Performance royalties pay for public performance
For a composition, public performance can include music broadcast or otherwise performed in licensed settings. Section 106(4) gives copyright owners the exclusive right to perform musical works publicly (17 U.S.C. § 106).
A performing-rights organization, usually shortened to PRO, licenses that composition right and distributes royalties under its rules. The composition’s performance income is commonly tracked in two parallel parts:
- the writer share, connected to the credited songwriter; and
- the publisher share, connected to the publisher or administrator of the composition.
“Publisher” does not necessarily mean a large company. A songwriter may be self-published, but the writer role and publisher role still answer different registration questions.
In film and television, the cue sheet is a key report. ASCAP says cue sheets document the music used in an audiovisual production and are used to distribute royalties for those performances (ASCAP cue sheets).
The license is not necessarily negotiated one song at a time. ASCAP says it offers bulk licenses covering its entire repertory rather than individual song licenses (ASCAP film-music checklist).
This is separate from the upfront sync license. Sync is permission to put music with picture. Later exhibition or broadcast of the production may create a composition performance that is reported through a cue sheet.
Mechanical royalties pay for reproducing the composition
A mechanical royalty belongs to the composition side. It comes from the right to make and distribute copies or digital deliveries of a nondramatic musical work.
The Copyright Office calls the Section 115 license the “115 License” or “Mechanical License” and explains that it covers making and distributing phonorecords of nondramatic musical works (Copyright Office Circular 73).
The same circular is explicit that Section 115 does not cover sound recordings. It covers reproduction and distribution of musical compositions (Copyright Office Circular 73).
“Mechanical” sounds like a word left over from physical manufacturing. The right still applies in digital systems. Title I of the Music Modernization Act created a U.S. blanket-licensing system for covered permanent downloads, limited downloads, and interactive streams (U.S. Copyright Office).
The Mechanical Licensing Collective, or The MLC, administers that blanket license. It says it collects royalties from digital music providers and pays songwriters, composers, lyricists, and music publishers (The MLC).
So an interactive stream can involve a composition mechanical even though no CD changed hands.
One stream can touch more than one right
The most useful model is a two-by-two grid:
| Property | Performance right | Reproduction right |
|---|---|---|
| Composition | Performance royalty to composition stakeholders | Mechanical royalty to composition stakeholders |
| Recording | Narrow statutory digital-performance right for certain transmissions | Recording-owner income handled under the recording-side arrangement |
The grid prevents a common mistake: assuming the service made one payment called “streaming royalties” and every right holder receives a piece from the same account.
There is no single streaming royalty that every rights holder draws a slice from.
Under the Music Modernization Act system, covered U.S. interactive streaming mechanicals move through the blanket license administered by The MLC (U.S. Copyright Office). Composition performance royalties move through performance-rights licensing. Recording-side payments follow the service’s recording license and the applicable owner or distributor arrangement.
For non-interactive digital radio, the recording has a separate statutory-performance lane. SoundExchange says it administers the Section 114 sound-recording license (SoundExchange registration).
That SoundExchange payment is not a composition performance royalty and not a mechanical. It is the digital-performance royalty for the recording.
Recordings do not have the same general performance right
This is the exception that makes casual explanations go wrong.
Section 114 says the rights of a sound-recording copyright owner do not include a performance right under Section 106(4) (17 U.S.C. § 114). Section 106(6) instead identifies public performance of sound recordings by digital audio transmission (17 U.S.C. § 106).
In plain English, the composition and recording do not travel through identical performance systems. Hearing a record played publicly may implicate the composition’s broad public-performance right, while the U.S. recording-side statutory right is tied to qualifying digital audio transmissions.
That is why a songwriter’s PRO account and a recording artist’s SoundExchange account are not substitutes for one another.
The SoundExchange explainer maps the 50/45/5 statutory recording split if you need to check that side next.
Writer share and publisher share are composition labels
The writer share is the songwriter-facing side of composition performance income. The publisher share is the publisher-facing side.
Those labels should not be carried into every royalty conversation. The MLC pays eligible songwriters and publishers under the digital mechanical blanket system (The MLC), but mechanical accounting and performance accounting are distinct systems. SoundExchange’s statutory split, meanwhile, names a recording owner, featured artists, and nonfeatured performers (17 U.S.C. § 114).
If you are a self-written, self-released artist, one human being may be:
- a writer of the composition;
- the self-publisher of the composition;
- the owner of the recording; and
- the featured performer on the recording.
That does not merge the rights. It means you need accurate records in each system relevant to those roles.
A film or TV use can create several payment events
When music is licensed under picture, the upfront permission is the sync transaction. Because a song has a composition and a recording, the buyer needs the appropriate permission for each property.
If the production is later broadcast, composition performance royalties depend on correct reporting. ASCAP explains that cue sheets are the primary means by which it tracks music in audiovisual productions and distributes royalties for those performances (ASCAP cue sheets).
That later performance royalty is not another sync fee. It comes from a different right. Nor is it a mechanical merely because the music exists inside a recorded episode.
Keeping those labels precise helps you ask better follow-up questions:
- Was the upfront license paid on both the composition and recording sides?
- Was the cue sheet filed with correct writer and publisher information?
- Is the composition registered for the mechanical systems that apply?
- Is the recording claimed for any relevant digital-performance system?
Mechanical rates change, but the category does not
The Copyright Office publishes a historical schedule of statutory mechanical rates, beginning with the two-cent rate under the 1909 Act and showing later changes (Copyright Office rate history).
That history is useful because it shows the rate is set and revised over time. It is not a safe basis for quoting a current cents figure without checking the current rule.
The stable definition is the one to remember: a mechanical concerns reproduction and distribution of the composition under Section 115 (Copyright Office Circular 73).
Use the two-question test on every statement
When a dashboard, distributor, publisher, or contract uses the word “royalty,” ask:
- Which property is earning: the composition or the recording?
- Which right is earning: performance, reproduction, or something else?
Then identify the role attached to the money: writer, publisher, recording owner, featured artist, or nonfeatured performer.
