If you write songs, one of the first organizations you will need to understand is a Performing Rights Organization, almost always shortened to PRO. A PRO is the body that licenses your compositions to the businesses that publicly perform music and then collects and pays out the resulting performance royalties. Without a PRO affiliation, a whole category of money your songs earn generally never reaches you. This guide explains what a PRO is, what it does and does not handle, and how it fits alongside the other organizations that pay musicians. If you are weighing which PRO to affiliate with, the PRO Comparison calculator can help you line the options up.

What a PRO actually does

A PRO sits between songwriters and the thousands of businesses that play music to the public. Radio stations, TV networks, bars, restaurants, gyms, live venues, and streaming services all perform copyrighted music, and under copyright law they need permission to do so. It would be impossible for each business to track down every songwriter, so PROs solve the problem with blanket licenses: a business pays the PRO, the PRO grants access to its entire catalog of songs, and the money flows back to the writers and publishers whose works were performed.

In plain terms, a PRO does four things:

  • Licenses your catalog to music users on your behalf.
  • Monitors and logs performances across radio, TV, venues, and digital services.
  • Collects the license fees those businesses pay.
  • Distributes the resulting performance royalties to songwriters and publishers.

This all happens at a scale no individual artist could replicate, which is the core reason PROs exist.

The composition, not the recording

The single most important thing to understand is that a PRO deals with the composition — the underlying song, the melody and lyrics — not the sound recording (the master). These are two separate copyrights, and they are paid through different systems. We unpack this split in detail in performance royalties explained.

Because PROs handle the composition’s public-performance right, they pay the people who wrote the song. If you are both the writer and the performer of your music, you wear two hats, and the PRO pays you for the writing hat.

What a PRO does not handle

A PRO is necessary, but it is not the whole picture. It deliberately leaves several large pools of money to other organizations:

  • Mechanical royalties from streaming and downloads in the US come from The MLC, not your PRO.
  • Sound-recording (master) digital performance royalties in the US come from SoundExchange.
  • International collection, YouTube Content ID, and sync are areas where a publishing administrator or other partner often layers on top.

We map the first two in MLC vs. SoundExchange, which is essential reading if you want to avoid leaving money uncollected. The takeaway: joining a PRO covers performance royalties on your compositions and nothing more, so you still need to register elsewhere for the rest.

Writer share and publisher share

Performance royalties on a composition are split into two halves: the writer’s share and the publisher’s share. The PRO pays each half separately. If you are signed to a publisher, the publisher collects its half. If you are self-published — which most independent artists are — you may need to set yourself up to collect both halves, which sometimes means registering a publishing entity with the PRO as well as affiliating as a writer.

This detail catches a lot of self-releasing artists off guard, and it is one of the most common ways performance money goes unclaimed. The PRO vs. publishing admin guide explains where a separate administrator can help with the parts a PRO does not reach.

How PROs fit into the bigger royalty picture

Think of your royalties as several distinct streams, each with its own collector. A PRO handles one of the most valuable streams — public performance of your compositions — but it works in parallel with the MLC, SoundExchange, and any administrator you use. Affiliating with a PRO is usually one of the earliest steps a serious songwriter takes, because performance royalties accrue whether or not you are collecting them, and unaffiliated writers simply miss out.

Once you understand the landscape, the practical questions become which PRO to join and how to register your works correctly. We cover the choice in ASCAP vs. BMI and the mechanics in how to register your songs with a PRO.

Frequently asked questions

Do I have to join a PRO to get paid? For performance royalties on your compositions, in practice yes — these royalties generally only reach you through a PRO affiliation. Other royalty types are handled by other bodies, so a PRO is one piece of a larger setup.

Does my PRO collect my streaming royalties? Partially. Streaming generates a public-performance component that your PRO handles, but the mechanical component in the US comes from The MLC, and the master side comes from SoundExchange. They are separate systems.

Is a PRO the same as a publisher? No. A publisher administers and exploits your songs commercially; a PRO is a collective licensing body that handles the public-performance right specifically. You can self-publish and still affiliate with a PRO.

Can I be in more than one PRO at the same time? You typically affiliate as a writer with one PRO at a time. Confirm each organization’s current terms before joining or switching, since policies change.

Which PRO should I choose? There is no universal best choice; it depends on eligibility, structure, tools, and fit. Compare the options side by side with the PRO Comparison calculator and read ASCAP vs. BMI.
