Carianne Marshall is leaving her role as co-chair and chief operating officer of Warner Chappell Music as parent Warner Music Group continues simplifying leadership across its businesses.
Marshall will transition out of her current position at the end of September, while Warner Chappell CEO and co-chair Guy Moot becomes the publisher’s sole chair effective October 1st. She will remain with Warner Music Group through the end of 2026 to assist with the transition.
Warner Music Group announced the change September 21st, describing it as part of an effort to streamline the company’s leadership structure.
Marshall’s exit ends a seven-year run at one of the world’s largest music publishers. She joined Warner Chappell in June 2018 and has co-led the company with Moot since 2019, occupying a role that reached across the creative, commercial and operational sides of a business built around songs rather than recordings.
That makes the change more consequential than an ordinary executive departure. Warner Chappell administers music rights, develops songwriters and licenses compositions across a global business where streaming, digital services and new technology have made accurate song administration increasingly valuable.
Guy Moot Becomes Warner Chappell’s Sole Chair
The immediate structural change is straightforward: Warner Chappell is moving from a co-chair model to one chair.
Moot, who has served as co-chair and CEO alongside Marshall, takes the sole-chair title October 1st. Warner has not announced a direct replacement for Marshall as co-chair or chief operating officer.
Music Week notes that Marshall will remain through December to help ensure continuity even after Moot formally assumes sole leadership.
The arrangement separates the leadership change from Marshall’s final departure. Her co-chair and COO roles end with September, but she remains with Warner during the final three months of the year as the company moves responsibilities into its new structure.
Warner has not detailed how Marshall’s COO responsibilities will be divided after she leaves. No next role for Marshall has been announced either.
Marshall Expanded Warner Chappell’s Publishing Operations
Marshall joined Warner Chappell in June 2018 after working as a partner at independent publisher SONGS, where she ran its West Coast office and led creative services and creative licensing.
Her earlier career included positions at Universal Music Publishing, DreamWorks Music Publishing and Elektra Records. At SONGS, she worked with a roster that grew to more than 300 songwriters and included Lorde, The Weeknd and Diplo, Warner’s executive biography notes.
One of Marshall’s early Warner Chappell initiatives was the creation of a Creative Services department designed to find additional commercial and creative opportunities for songwriters.
That work became part of a wider expansion during her tenure with Moot. Warner credits Marshall with helping modernize digital licensing, strengthen creative services and grow the company’s roster during a period when streaming dramatically increased the global reach of songwriting rights.
In her departure statement, Marshall recalled that she and Moot had set out to build a “songwriter-first home” and pointed to the company’s growth and internal culture among the achievements she valued from the period.
Her operational role also placed her close to the systems that turn songs into revenue beyond their original releases, including digital licensing, synchronization and other uses of compositions across media and technology platforms.
Publishing Controls the Song Beneath the Recording
Warner Chappell can be less visible to listeners than Warner Records, Atlantic or another record label because publishing operates on a different side of music rights.
A record label generally deals with the sound recording, or master. A music publisher works with the underlying composition: the melody, lyrics and songwriting embodied in that recording.
Those rights can be owned and administered separately. A recording released by one label may contain a song represented by several publishers because multiple writers contributed to the composition.
Streaming, public performance, broadcast, synchronization and reproduction can all generate publishing income separately from the master recording. Publishers help administer those rights, negotiate licenses, collect income and account back to songwriters and other rightsholders.
Warner Chappell operates at enormous scale. The company says its catalog contains more than one million copyrights spanning standards and major contemporary songs, alongside a global songwriter roster working across pop, hip-hop, country, Latin, dance and other genres.
That scale is what turns an executive restructuring into a songwriter story. Leadership decisions affect a company responsible for administering compositions that can continue generating royalties across countries and platforms for decades.
Songwriter Royalties Are Becoming More Complex
The publishing business Marshall is leaving is also more technologically complicated than the one she joined in 2018.
Streaming created continuous global usage of songs across dozens of markets, while social video, gaming, fitness platforms and other digital services added licensing environments beyond conventional recordings, radio and television.
For publishers, growth in those uses creates an administrative challenge as well as a commercial opportunity. A song can generate small amounts of revenue from enormous numbers of transactions, making data matching, licensing and royalty collection central parts of the business.
Artificial intelligence has introduced another rights question. Publishers are increasingly confronting how copyrighted compositions may be used in AI training, when licensing should be required and how songwriters should be compensated when generative technology interacts with protected music.
Marshall’s operational background sat directly inside that changing environment. Warner specifically credits her tenure with modernizing digital licensing while expanding the creative services available to writers.
Moot will now oversee Warner Chappell as sole chair while those responsibilities continue to evolve.
Warner Is Moving Away From Co-Chair Structures
The Warner Chappell change fits a broader shift inside Warner Music Group rather than standing entirely on its own.
Trade reporting around Marshall’s departure has connected it with WMG’s effort to simplify senior management and move away from co-chair structures across some of its businesses. The change leaves Moot as the single chair at Warner Chappell instead of maintaining the arrangement he and Marshall have shared since 2019.
A similar transition occurred at Warner Records earlier in 2026. Tom Corson moved from his co-chair and COO position at the label into the newly created Warner Music Group COO role, while Aaron Bay-Schuck became Warner Records’ sole chair and CEO.
That change concentrated Corson’s operational responsibilities at the parent-company level while leaving Warner Records with one top chair. Warner Chappell is now moving in the same broad direction, although Warner has not said that every responsibility previously handled by Marshall will follow the same model.
WMG CEO Robert Kyncl has been reshaping the company’s organization around a more coordinated global structure, with technology and shared operations increasingly handled across divisions.
Marshall’s departure therefore arrives during a wider reworking of how Warner distributes executive responsibility, not simply a change at the top of its publishing arm.
Warner Chappell Competes for Songs and Songwriters
Leadership also matters because major publishers compete over two closely connected assets: established song catalogs and the writers creating the next generation of music.
Catalog compositions can produce recurring income through streaming, performance, synchronization and other licensing long after their original release. New songwriting agreements, meanwhile, give publishers an opportunity to participate in music that may generate rights income for years to come.
Administration is central to both. Owning or representing a valuable composition means little if its uses are not identified, licensed and accounted for accurately across markets.
Warner Chappell competes with Sony Music Publishing, Universal Music Publishing Group and a wide range of independent publishers for those rights and relationships. Creative support can become part of that competition alongside advances, royalty terms and administration.
Marshall’s Creative Services initiative reflected that broader strategy. Instead of treating publishing as royalty collection alone, the department was built to create additional opportunities around songs and the people writing them.
Her exit does not change Warner Chappell’s fundamental business. It does place responsibility for that business under a simpler top-level structure as Moot moves from co-chair to sole chair.
A Seven-Year Chapter Ends in December
Marshall’s executive titles change at the end of September, but her Warner chapter will not formally close until the end of 2026.
The transition gives Moot and the existing management team three months to move responsibilities into the new structure rather than making the departure immediate.
“Our talented team will build upon the incredible foundation Carianne has put in place,” Moot said in Warner’s announcement, thanking her for her impact on the publisher.
Marshall has not announced what comes next. Her own statement focuses on the company she is leaving rather than identifying another venture or executive position.
For Warner Chappell, the immediate consequence is already clear. A publishing business co-led by Moot and Marshall for more than seven years will enter 2027 with one chair.
The songs under its administration will keep generating streams, performances, licenses and royalties regardless of who holds the titles above them.
How Warner Chappell turns those uses into value for songwriters is what makes the leadership change consequential.
