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, 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, type:

make release

If something goes wrong, then remove the whole build subdirectory with make clean and start new with make release.


To start MuseScore, type:


The Start Center window will appear on every invocation until you disable that setting via the "Preferences" dialog.


To install to default prefix using root user, type:

sudo make install

Debug Build

A debug version can be built by doing make debug instead of make release.

To run the debug version, type:



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!

You can’t perform that action at this time.
