Harrison Lee
and composer
I recently have switched over to MuseScore 4 to notate some pieces as opposed to Finale or Sibelius because it feels more intuitive to me.
Josh Mancell
If only MuseScore had existed back then, I most certainly would have used it instead of transcribing all the parts by hand!
Mike Thompson
Now, a young writer can download MuseScore 4 and access a strong engraving and composing suite and super high-quality sounds, all free and lightweight enough to run on the average computer.
History of Muse
Muse Group started with Ultimate Guitar in 1998, created by Eugeny Naidenov. Over time 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. And Muse Group has only continued to grow from there, adding Audacity, StaffPad and many more to the roster.
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, building the tools over 400 million musicians use every year.
Explore the full timeline of milestones, products, and people that shaped Muse Group — from both the Ultimate Guitar and Hal Leonard sides of our story.
