A mechanical royalty is money owed to the owner of a composition when a recording of that composition is reproduced or streamed.
The mechanism
It attaches to the composition rather than the recording, and for digital services in the United States it is administered collectively. Rates are set by regulation rather than negotiated per use.
A worked example
When a song is streamed, the recording generates money for the master owner and the composition separately generates a mechanical for the writer and publisher.
What it is confused with
- Performance royalty Performance royalties are for public performance and are collected by PROs. Mechanicals are for reproduction.
- Master versus composition Mechanicals are one of the payments arising from the composition side of that split.
Why it matters
It is the payment most often lost to registration failure, which is why it dominates the black box.
