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): 

<code>configure.run()</code>

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:**
<code>C:\Program Files\MuseScore 3\bin\MuseScore3.exe</code>
**Mac**
<code>/Applications/MuseScore 3.app/Contents/MacOS/mscore</code>
**Linux**
<code>/usr/bin/musescore3</code>

Attention! If MuseScore cannot be found under this path on Linux, it helps to install MuseScore via apt:

<code>sudo add-apt-repository ppa:mscore-ubuntu/mscore3-stable
sudo apt-get update
sudo apt install musescore3</code>
