To complete the MuseScore integration in music21, the following command is sufficient in most cases (it can be executed in an empty Jupyter Notebook page):
configure.run()
If after that the note display in Jupyter/music21 still does not work, open [[https://analyse.hfm-weimar.de/scripts/Setting_up_music21.ipynb|this]] Notebook.
Here you can directly view and change the path settings for MuseScore within music21.
The usual paths for MuseScore are:
**Windows:**
C:\Program Files\MuseScore 3\bin\MuseScore3.exe
**Mac**
/Applications/MuseScore 3.app/Contents/MacOS/mscore
**Linux**
/usr/bin/musescore3
Attention! If MuseScore cannot be found under this path on Linux, it helps to install MuseScore via apt:
sudo add-apt-repository ppa:mscore-ubuntu/mscore3-stable
sudo apt-get update
sudo apt install musescore3
