Ultimate Guitar
Ultimate Guitar is the world's largest guitar tablature platform, founded in 1998, hosting more than 1.8 million user-submitted tabs and chord sheets. The site transitioned from a free community-driven resource to an aggressive freemium model under Muse Group, with a Pro subscription (about $99.99/year or $24.99/month in the US) required for ad-free access, Official tabs, and advanced interactive playback tools. Muse Group, majority-owned by founder Eugeny Naidenov (private equity firm Francisco Partners held a minority stake from 2023 until June 2026), also owns MuseScore, Audacity, StaffPad, and Hal Leonard, the world's largest sheet music publisher.

Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Student Eugeny Naidenov started the site in Kaliningrad, Russia, as Zappp's Guitar Archive, a free archive of volunteer-submitted tabs that was soon translated into English and renamed Ultimate Guitar. There were no paywalls; the site operated in the same copyright gray area as its many rivals.
When music publishers pressured US tab sites such as OLGA and MxTabs to close in 2006, UG stayed online by citing its Russian jurisdiction and absorbed their users; comScore counted 1.4 million visitors in July 2006, double a year earlier. The site stayed free and ran on display advertising, which forum users were calling intrusive by 2009.
UG launched a $1.99 paid iOS app in March 2010 and signed a Harry Fox Agency licensing deal in April, moving from gray-area hosting to licensed tabs with royalties paid to publishers. Paid online services (UG Plus, Tab Pro) followed, and contributors were rewarded with free Tab Pro time from 2012, but publisher takedown requests removed batches of popular tabs from 2013. By 2016 the 40-person company had 11 million registered users while mobile use was cutting its ad revenue; it bought MuseScore in 2017.
In February 2018 UG made its apps free and moved to monthly and annual Pro subscriptions, putting Official tabs, interactive-player tools and ad-free use behind Pro. Users soon complained of the heaviest ad load among tab sites, 'free trial' sign-ups that turned into annual charges, prices that differed between web and app, and limits on saving tabs for free users.
UG's leadership formed Muse Group and bought Audacity days later, followed by weeks of backlash over Audacity's contributor license and privacy policy and a deportation remark by the group's head of strategy against a developer who had built a MuseScore paywall bypass. On UG, users complained that accurate community tabs were being displaced by Pro-only Official tabs, paying subscribers got full-screen upsells, and the mobile site pushed users into the app.
Muse Group closed its acquisition of Hal Leonard, the largest sheet-music publisher, on December 1, 2023, with a minority investment from private equity firm Francisco Partners, which also backed a new chief operating officer. UG added Pro-only Practice Mode and a separate Hal Leonard songbook subscription, and users reported discount emails built on inflated list prices such as '95% off' $499 a year.
From February 2025 UG raised annual prices sharply in some markets (UK £19.99 to £29.99), moved website printing behind Pro in April, and in July briefly removed free downloads of community Guitar Pro files before restoring them after contributor protests. A June 2025 auto-renewal class action was voluntarily dismissed in February 2026 without a ruling, and Francisco Partners exited in June 2026 through a debt-financed buyout that left the founder in control. Billing and refund complaints continue.
Alternatives
Free, open-source music notation software with a large community library of user-submitted scores. Owned by the same parent company (Muse Group) but the notation app itself is free and open source. The online sheet music library (musescore.com) has moved to a subscription model, though the desktop app remains fully free.
Interactive tab platform with Guitar Pro-style playback; the free tier includes all tabs with basic playback. The paid Plus tier ($9.99/month) adds speed control, looping, printing, backing tracks and ad-free use. Smaller catalog than UG, but tabs are often praised for accurate fretboard positions.
Chord-recognition tool that generates chord charts automatically from songs on YouTube and other sources. The free tier gives basic chord charts; Premium adds transposing, capo, looping, MIDI and PDF downloads, and offline mode. It auto-generates chords rather than relying on user-submitted tabs, so it covers songs no one has transcribed.

Timeline (45 events)
Eugeny Naidenov launches Ultimate Guitar from Russia
Student Eugeny Naidenov in Kaliningrad, Russia, creates a website originally called Zappp's Guitar Archive after failing to find the tablature for a Guns N' Roses song. The site is initially published in Russian before being translated to English and renamed Ultimate Guitar. All content is free and community-contributed.
MPA launches legal crackdown on guitar tab websites
The Music Publishers' Association issues a statement announcing active pursuit of tablature websites for copyright infringement. MPA president Lauren Keiser threatens fines and imprisonment for operators of unauthorized tab sites. OLGA, MxTabs, Taborama, and other US-based tab sites are forced to shut down.
Ultimate Guitar survives MPA crackdown via Russian jurisdiction
As the Music Publishers' Association and the National Music Publishers' Association pressure US tab sites such as OLGA to shut down or pull their tabs, Ultimate Guitar keeps operating: executive vice president Doug Osborn tells The New York Times the site violates no laws because its headquarters are in Russia and it complies with Russian law. Displaced users migrate, and comScore counts 1.4 million Ultimate-Guitar.com visitors in July 2006, double the figure a year earlier.
Forum users complain about intrusive ads on UG
A November 2009 thread in UG's own forum collects complaints about the site's advertising, including ads for unrelated products and a pop-out ad that blocked scrolling until it was closed; several users recommend ad blockers. Display advertising was then UG's main way of paying for the site, before paid apps and subscriptions.
Ultimate Guitar launches Ultimate Guitar Tabs iOS app
Ultimate Guitar launches Ultimate Guitar Tabs, a paid app for iPhone, iPad and iPod touch giving licensed access to its tab database. It launched at $1.99 and within about a week reached No. 1 among paid music apps in the App Store. UG's apps would later pass 53 million downloads.
Harry Fox Agency licensing deal legitimizes UG's tab library
Ultimate Guitar enters a licensing arrangement with the Harry Fox Agency covering lyrics display, title search and tablature display with download and print capabilities; HFA's more than 44,000 represented publishers can opt in. The deal adds to UG's existing direct licenses with publishers. The royalties go to publishers and songwriters, not to the volunteer transcribers who create the tabs.
Forum debate surfaces over whether tab contributors deserve compensation
A thread in UG's Site Suggestions forum asks whether tab contributors should be paid now that UG charges for its smartphone app, since their submissions make the app possible. Replies note that UG's revenue had always come from advertising and suggest significant contributors should at least get free access to paid services; one recalls tab reviewers being offered temporary free UG+ access. Contributors' main reward remains UG IQ reputation points.
UG rewards Guitar Pro and Power Tab contributors with free Tab Pro access
UG announces that contributors of Guitar Pro and Power Tab files will get free access to Tab Pro, part of its paid UG Plus online service: one month for up to 5 approved tabs, three months for 6 to 10, and six months for more than 10, with bonus access to be given to contributors regularly from then on. It is the first formal reward for contributors beyond reputation points.
Publisher takedown requests remove batches of popular Guitar Pro tabs
Users in UG's Tab Talk forum report tabs replaced by the notice 'This tab has been removed at the request of the publisher', including tabs they transcribed themselves; by July 2013 one user says nearly every Guitar Pro tab for Metallica, Red Hot Chili Peppers and Guns N' Roses is gone. Licensing brought publisher control over which tabs UG can host.
UG dominates Google search results for guitar tabs
With its main US rivals shut down by the 2006 publisher crackdown and the largest tab catalog on the web, Ultimate Guitar becomes the default result for 'song name + tab' searches. Organic search remains its largest traffic source: about 64% of desktop visits in SimilarWeb's 2026 data.
The Guardian profiles UG: 40 staff, 11 million users, falling ad revenue
The Guardian reports that UG, run from Kaliningrad by about 40 employees who work 9am to 3pm, has 11 million registered users and turnover of 'several million dollars per year'. COO Mikhail Trutnev says the site saw a significant drop in ad revenue as users moved to smartphones, pushing the team to innovate through constant small experiments. Naidenov recalls turning the publishers' cease-and-desist campaign to UG's advantage as competitors closed.
Ultimate Guitar acquires MuseScore notation platform
Ultimate Guitar acquires MuseScore, the open-source music notation tool and its sheet music sharing platform. The acquisition marks UG's first step beyond the guitar tab segment into the broader music tools market. MuseScore's online repository would later be paywalled for copyrighted score downloads under the same management.
UG switches from paid app to freemium subscription model
Ultimate Guitar drops its paid-app and Lifetime-subscription model and moves to monthly and annual subscriptions, making its apps free to download and 1.1 million tabs and chords free to view. Official tabs with backing tracks, advanced interactive-player tools and ad-free access require Pro. Everyone who bought the app before February 2018 is granted a Lifetime subscription.
UG publishes 'myth-busting' post on its pricing and cancellation practices
A UG project manager's blog post (its original web address read 'Don't trust Russians and their shady pricing') answers complaints about Pro pricing, cancellation, refunds and support. It concedes pricing 'used to be shady' before February 2018, says monthly plans are not refunded, and says annual plans are refundable only if cancelled within 14 days.
Users complain UG has the heaviest ad load of any tab site
A forum thread titled 'Why is Ultimateguitar so heavy on advertisement?' says UG has 'the highest number of ads, interruptions, annoyances' of any tab site, even with an ad blocker, and complains of constant prompts on mobile to buy the app, lessons and upgrades. Other users reply that ads pay for song licensing.
Users find Pro prices differ between web and app
A forum user asks why UG Pro costs C$29.99 a year on desktop but C$19.99 a year in the phone app. A UG staff member replies that special offers change all the time and prices on different platforms vary, while the features are the same whatever price is paid. No rate card explains the differences.
MuseScore.com paywalls community-uploaded sheet music downloads
Under Ultimate Guitar's ownership, MuseScore.com restricts downloads of copyrighted sheet music to paid Pro subscribers only. Previously free downloads of community-uploaded scores are locked behind a paywall, with the company citing copyright compliance. The move mirrors UG's own pattern of monetizing volunteer-created content, as community contributors who uploaded scores for free sharing find their work gated behind subscriptions.
Users report being charged for a full year on starting a 'free trial'
A user who signed up for UG Pro's 7-day free trial finds he was charged for a full year with auto-renewal and cannot find the cancel option. UG staff reply that he chose a 12-month plan without a trial; the user calls the flow 'incredibly deceptive' because the signup screen said 'access Pro for Free.' Similar trial-to-annual complaints appear in UG's forum from 2018 and later on the BBB.
UG limits copying of tab content for free users
A forum user reports that copying from a tab page brings up a message that free users can only copy plain text, while Pro users can download the tab as a PDF. Saving tabs as documents is steered toward the Pro subscription.
Muse Group acquires StaffPad notation app
Muse Group acquires StaffPad, a pen-and-touch music notation app for iPad and Windows Surface devices built on handwritten-notation recognition. UK filings date the deal to December 2020; it was announced in May 2021 with audio staves and transcription features planned. With MuseScore, the group now owns two notation apps.
Users complain accurate community tabs are displaced by Pro-only versions
A long-time user writes in UG's forum that 'the good tabs are being changed to pro status', that accurate versions of songs he learned are now Pro tabs costing money, and that half the tabs on his playlist of learned songs have gone. He notes the paid app he once bought had let him view all tabs.
Muse Group formed as corporate umbrella for music tool brands
Ultimate Guitar's leadership forms Muse Group as a parent company for Ultimate Guitar, MuseScore, the MuseClass education platform and the Tonebridge effects app, announcing the Audacity acquisition days later. Founder Eugeny Naidenov becomes chairman and Michael Trutnev CEO. Muse Group later moved its headquarters to Limassol, Cyprus (holding company MuseCY Holdings Ltd.).
Muse Group acquires open-source audio editor Audacity
Muse Group acquires Audacity, the free and open-source audio editor launched in 2000, pledging to keep it free. Audacity had been downloaded more than 100 million times on FossHub alone. Within weeks, changes to its contributor license agreement and privacy policy would spark a major community backlash.
Muse Group introduces controversial CLA for Audacity contributors
Muse Group introduces a Contributor License Agreement for Audacity that gives the company unlimited rights over how contributed code is used and licensed, including dual licensing. The CLA's FAQ states that contributed code may be used in future closed-source projects by Muse Group. Contributors object that this breaks with Audacity's 20-year GPL heritage.
Audacity branded 'spyware' after Muse Group adds telemetry
A draft Audacity privacy policy says Muse Group will collect data 'necessary for law enforcement, litigation and authorities' requests,' may share personal data with parties including potential buyers and law enforcement, keeps IP addresses in identifiable form for a day, and tells users under 13 not to use the app. It follows a May proposal, later dropped, for opt-in analytics through Google and Yandex. FOSS Post labels Audacity possible spyware, and users start forks such as Tenacity.
Muse Group head of strategy threatens developer with deportation
Daniel Ray, Muse Group's Head of Strategy, posts a comment on GitHub implying that developer Wenzheng Tang ('Xmader'), who created tools bypassing MuseScore Pro subscription fees, could be deported to China where he had been a vocal critic of Beijing. Tang states 'If I am deported back to mainland China, I would at least be jailed.' Ray later claims the message was not intended as a threat.
Muse Group reverses Audacity privacy policy after backlash
Following weeks of intense backlash, Muse Group revises Audacity's privacy policy to clarify it will not collect user data and deletes the clause about working with law enforcement agencies. The reversal demonstrates the company's pattern of pushing data monetization boundaries and retreating only when community pressure becomes overwhelming.
Pro subscribers complain of full-screen upsell ads in the app
A paying subscriber reports that UG's app showed a full-screen ad for its lessons that he could not dismiss without scrolling through every screen, just as he started a gig; other subscribers report lesson ads each time they open the app. They argue a paid subscription should not bring in-app upsells.
UG retains user-submitted tabs after account deletion
Ultimate Guitar's help center says deleting an account permanently removes forum posts, comments, friendships and personal data, but not the tabs and articles the user submitted. Contributors' work stays on the platform, earning subscription and ad revenue, after they leave.
Android users report being pushed from the mobile site into the app
A Pro subscriber reports that opening UG in his phone's browser prompts him to choose between the app and the web page, and that choosing the web page still forces him into the app, where transposing had disappeared. Pushing mobile web users into the app is a recurring complaint about UG's mobile experience.
Muse Group acquires Hal Leonard with Francisco Partners PE backing
Muse Group acquires Hal Leonard, the world's largest sheet music publisher, with growth investment from Francisco Partners, a private equity firm. The combined entity controls a library of over 5.5 million scores, tabs, and compositions. The deal creates vertical integration between music publishing rights (Hal Leonard) and distribution platforms (Ultimate Guitar, MuseScore).
User reports '90% off' email leading to '95% off' a $499/year price
A reader commenting on a Guitar Chalk review of UG Pro reports seeing prices around AU$60 a year at a '75% off' special, then receiving an email offering 90% off that led to a page offering 95% off an annual subscription listed at $499. Another commenter describes a '90% off New Year sale' email that never showed the actual price.
Ultimate Guitar launches AI-powered Practice Mode
Ultimate Guitar releases Practice Mode, a machine-learning feature that listens to guitar practice sessions through the device microphone and provides feedback on pitch and rhythm accuracy. Available on iOS, the feature adds interactive learning to the platform but is restricted to Pro subscribers, adding another paywalled feature atop user-created content.
Hal Leonard songbooks arrive on UG behind a separate Songbook subscription
Muse Group announces that 2,000 best-selling Hal Leonard books, including Berklee Press, Hal Leonard guitar methods and The Real Book, are available on both MuseScore and Ultimate Guitar, for unlimited browsing with a Songbook subscription or, on MuseScore, one-off purchase with Muse Credits. It adds another paid tier and puts the group's own publisher's catalog in front of UG users.
BBB documents pattern of unauthorized charges and refund denials
Ultimate Guitar's BBB profile, rated F, accumulates complaints about subscription billing. Users describe being charged for Pro+ or songbook add-on subscriptions after free trials or small purchases they did not expect to renew, and being offered only partial refunds (such as 25%) or extra subscription time instead of a full refund.
Muse Group unifies Hal Leonard US and Europe into global operation
Muse Group says Hal Leonard's US and European teams now operate as one global organization and that the integration delivered double-digit growth. MuseScore subscribers gain access to official Hal Leonard scores, Hal Leonard songbooks are featured on Ultimate Guitar and MuseScore, and thousands of Hal Leonard scores and songbooks have been digitized on MuseScore. Muse Group says it reaches more than 400 million users.
Annual subscription price increased by 50%
UK users report Ultimate Guitar's annual subscription rising from £19.99 to £29.99 from February 2025, a 50% increase; Australian users report renewals rising from AU$25 to AU$30 or AU$49.99. Posters call the pricing 'scammy', citing countdown offers that reset and prices that differ between web and app stores.
Guitar community declares 'Ultimate Guitar is dead'
A SevenString.org thread titled 'Ultimate Guitar is dead' catalogs users' frustrations with UG under its newer ownership: constant prompts for new features, glitches that force frequent app restarts and blank-screen crashes, and newly added songbooks that took certain tabs down and locked them behind another paywall, plus resentment of a business built on tabs the company did not create. Posters compare UG unfavorably with other tab sources.
UG moves website printing behind the Pro subscription
After users report in late March 2025 that a Pro prompt now blocks printing tabs they had printed for years, UG Support confirms that 'Printing is part of the Pro service' and that 'due to recent requirements' printing on the website has been disabled for free users. Users add that printing of personal tabs and edits is also blocked; months later a support reply says 'Our team can't do anything about it.'
Class action lawsuit filed over auto-renewal subscription traps
Plaintiff Steven Teilmann files a class action complaint (Case No. 3:25-cv-05310) against Ultimate Guitar USA LLC in the Northern District of California. The lawsuit alleges UG surreptitiously enrolls consumers in auto-renewing subscriptions without clear consent, fails to provide required disclosures under California's Automatic Renewal Law, and makes cancellation 'exceedingly difficult and unnecessarily confusing.'
Refund policy silently modified without user notification
A consumer complaint to the BBB documents that the refund clause in Ultimate Guitar's Terms of Service was changed between July 14 and 15, 2025, narrowing it to a partial refund (the difference between the annual and monthly fee) for cancellations within 14 days, while the page still showed a June 15, 2021 revision date and gave no notice or versioning. The change came weeks after the Teilmann class action was filed.
Guitar Pro download button disappears for free users, then returns after protests
Free users find the button for downloading community-submitted Guitar Pro files gone from UG's desktop site; contributors protest having to pay to access files they uploaded, cite the Terms of Service license, and some threaten to remove their tabs. UG Support first says the team is 'trying to figure out the reasons' and on July 23 says the button is back, though users in some countries still report it missing. UG never explains the change.
Trustpilot reviewers describe inflated list prices behind '90% off' emails
Trustpilot reviewers describe emails offering '90% off' an annual subscription with an alleged list price of £400 a year, making the real price look like a steep discount; others report being charged after cancelling free trials, and Trustpilot's review summary notes reports of double charges and difficulty obtaining refunds. UG's Trustpilot page has nearly 2,000 reviews, many about billing, pricing and refunds.
Auto-renewal class action against UG is voluntarily dismissed
In Teilmann v. Ultimate Guitar USA (N.D. Cal., 3:25-cv-05310), the plaintiff filed an amended complaint in October 2025 after UG's first motion to dismiss, UG moved to dismiss again in December 2025, and on February 2, 2026 the plaintiff filed a notice of voluntary dismissal and the case was terminated. No class settlement or ruling on UG's auto-renewal practices was entered.
Francisco Partners exits Muse Group in a debt-financed buyout
Muse Group announces the conclusion of Francisco Partners' 2023 minority investment. The stake is bought out with senior credit facilities arranged by J.P. Morgan and cash on hand, with no new equity investor, leaving founder and CEO Eugeny Naidenov as majority owner alongside executive chairman and COO Mo Chahdi. A Francisco Partners adviser says Muse more than tripled in size during the investment; the group says it will pursue AI features and selective acquisitions.
