Who are we?

Muse Group began life as Ultimate Guitar, the largest online global community of musicians. Eugeny Naidenov founded Ultimate Guitar in 1998, with a dream to make it easy for guitarists to play songs by Guns ‘N’ Roses and his other favorite rockers. From there, the site grew from a plucky, tab-sharing trailblazer into a global leader of online music publishing. 

In 2017, Ultimate Guitar acquired MuseScore, expanding its reach into sheet music. Muse Group has only continued to grow from there — and now includes Audacity, StaffPad and many more. 

In 2023, Muse Group acquired Hal Leonard, the legendary global sheet music publishers, adding an unparalleled music catalog and educational expertise to the team.

Today, we are an international, visionary team of creatives, music lovers and audio obsessives, developing products we could not live without.
