MUSX File - Finale Notation File - What is .musx file and how to open it?
What is a MUSX file?
The ‘.musx’ file is the proprietary project format for MakeMusic Finale, the industry-standard music notation software. Functioning as a comprehensive digital score, a MUSX file encapsulates the complete blueprint of a musical piece—including every note, rhythmic value, dynamic marking, and articulation symbol. Beyond the raw musical data, this versatile format also stores essential metadata such as the work’s title, the composer’s name, and copyright details, making it a self-contained repository for both the artistic and administrative aspects of a composition.
People who compose music use MakeMusic Finale to make, edit, and listen to their musical creations. For example, someone might use Finale to write new version of song, add lyrics to it and then play it on their computer to make sure everything sounds right.
When composers save their work in Finale, it is saved as MUSX file. Inside this file, there is not only musical notes but also data that helps Finale play back music when you want to listen to it.

MUSX vs. MUS: Understanding the Difference
The key difference lies in the underlying technology. The old ‘.MUS’ is a proprietary binary format—a single, dense block of data. The modern ‘.MUSX’ is an open XML-based format— a structured, readable collection of files. Think of it as the difference between a sealed, uneditable photograph (.MUS) and a layered Photoshop file where you can adjust each element individually (.MUSX). This makes MUSX the superior choice for long-term archiving and complex professional work.
How to open a MUSX file?
Open MakeMusic Finale program. Then, go to menu at top of the screen and click on “File.” After that, choose “Open…” from options. Find your MUSX file on your computer and click on it to open it.
