Muse Group
Owns Ultimate Guitar, MuseScore, Audacity, and Hal Leonard, the main hubs for tabs, scores, and audio editing.
On the record
Checkpoint: Ultimate Guitar Pro subscriber trend and Chordify penetration data next reported
The call
Muse Group's four brands still draw crowds no AI tool has replaced, but the debt from its June 2026 buyout and unresolved AI tab quality question sit over the business.
Muse Group runs four music tools: Ultimate Guitar (tabs and lessons), MuseScore (sheet music), Audacity (audio editing), and Hal Leonard (licensed music content). The company has stayed ahead for two decades because millions of users upload tabs and scores that other people search for, and because some of what it owns is legally licensed, making it hard for Adobe or Apple to simply copy. The catch is that AI tools like Chordify can now detect chords from songs automatically, and if that technology gets good enough over the next few years, the huge library of user-uploaded tabs might stop being as valuable, which would hurt Ultimate Guitar's paying subscribers and the whole company's worth.
Why
01
AI pressure: Chordify and generative AI chord/tab detection tools. If AI-generated tabs get good enough, hobbyists stop paying Ultimate Guitar Pro for what a free tool can guess. Could AI do the core job? Only partly.
02
Bigger players: Adobe Audition, Apple Logic/GarageBand, Fender Play. Bigger players could bundle tabs, scoring, and audio editing into their own apps but haven't focused on it. Could a giant copy it? Probably.
03
What protects it. Millions of user-uploaded tabs and scores plus 20 years of community accuracy that new AI tools can't fully replicate yet.
What would change this call
Ultimate Guitar Pro subscriber count trend over next 12 months. Whether AI tab tools are eroding its core paid product.
Chordify or similar AI tool reports user growth or partnership news. Whether an AI competitor is gaining real market penetration.
News on J.P. Morgan credit facility terms, covenants, or restructuring. Whether debt load is constraining Muse Group's hiring or M&A capacity.

Key numbers
- Ultimate Guitar has 30 million monthly users
- 2.1 million tabs hosted on Ultimate Guitar
- Audacity downloaded over 100 million times
Named risks
- J.P. Morgan debt from June 2026 Francisco Partners buyout could constrain hiring and M&A over next 18 months.
- AI-generated tabs/chords reaching hobbyist-acceptable quality could erode Ultimate Guitar Pro subscriber base.
- Community backlash if Muse Group trains AI on user-generated tabs/scores without consent, echoing 2021 Audacity controversy.
- No audited financials disclosed, limiting visibility into true cash flow and debt-service capacity.
- Conflicting and unreliable third-party headcount/revenue estimates complicate outside assessment of company health.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Chordify | contesting | AI chord-detection tool posing live but not yet material threat to Ultimate Guitar tabs as of 2026 |
| Adobe Audition | contesting | Adjacent incumbent audio editor, slow/unfocused competitor to Audacity, no confirmed share loss |
| Apple Logic Pro/GarageBand | contesting | Bundled free/paid alternative to Audacity, has not displaced Audacity's 100M+ download base |
| Fender Play | contesting | Guitar learning competitor, described as unfocused rather than structurally blocking Ultimate Guitar |
Questions people ask
- Is Muse Group profitable?
- Muse Group discloses no audited financials as a private company. In June 2026 it financed Francisco Partners' full exit via senior credit facilities arranged by J.P. Morgan plus cash on hand rather than raising new equity, suggesting positive cash flow but no public profit figures exist.
- Who owns Muse Group now?
- Founder and CEO Eugeny Naidenov retains majority ownership and control as of June 2026. Francisco Partners, which took a minority stake in December 2023 to fund the Hal Leonard deal, fully exited on June 3, 2026 via a J.P. Morgan-financed buyout.
- Could AI replace Ultimate Guitar's tab library?
- AI chord-detection tools like Chordify pose a live but not yet material threat. As of 2026 Muse Group claims Ultimate Guitar still hosts over 2.1 million tabs with roughly 30 million monthly active users, with no confirmed subscriber decline tied to AI tools.
- Is Audacity safe to use after the Muse Group privacy controversy?
- In July 2021, Muse Group faced a 'spyware' backlash over an Audacity privacy-policy update after acquiring the app. As of late 2025 fact-checkers still reference this episode when assessing Audacity's data practices under Muse Group.
- Who is Muse Group's biggest competitor?
- No single rival matches its combined footprint. Adobe Audition, Apple's Logic/GarageBand, and Fender Play are slow-moving incumbents in adjacent markets, while AI chord-detection tool Chordify represents the more direct, emerging substitution threat to Ultimate Guitar.
- Is Muse Group cutting jobs after the Francisco Partners exit?
- No layoffs have been reported. In its June 22, 2026 announcement, Muse Group said it had 'more than tripled in size' during its roughly 2.5-year Francisco Partners partnership and signaled plans for continued selective acquisitions and AI investment.
