Read the developer handbook for a complete build walkthrough and a list of dependencies.

Getting sources

If using git to download repo of entire code history, type:

git clone
cd MuseScore

Otherwise, you can just download the latest source release tarball from the Releases page, and then from your download directory type:

tar xzf MuseScore-x.x.x.tar.gz
cd MuseScore-x.x.x

Release Build

To compile MuseScore for release, type:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release

If something goes wrong, append the word "clean" to the above command to delete the build subdirectory:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release clean

Then try running the first command again.


To start MuseScore, type:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release run

Or run the compiled executable directly.

Debug Build

A debug version can be built and run by replacing

in the above commands.

If you omit the

option entirely then
is used by default, as it provides a useful compromise between Release and Debug.


See mtest/ or the developer handbook for instructions on how to run the test suite.

The new script testing facility is also available to create your own automated tests. Please try it out!
