NOTE

The author of musdl does NOT condone piracy in any way, and is not responsible for anything that happens as a result of piracy arising from the use of musdl.

musdl (musscore downloader) is a downloader for Musescore, written in Python.

The easiest way to download the score is through the CLI:

musdl (musescore url)

To convert to another format, use -f/--format:

# export as midi
musdl -f mid (musescore url)

For a complete list of formats, run musdl --help. If you want to export in any format besides mscz, you need to install musescore first.

It can also be imported and used as a module:

from musdl import Score, OnlineScore

my_score = OnlineScore("musescore_url")

# Read the score's metadata,
name = my_score["workTitle"]
# or save the whole score...
my_score.export("mscz", "my_score.mscz")

# ...and then load it again.
my_score = Score.from_file("my_score.mscz")

For API documentation, see here.

How it works

I just copied over the IPNS-specific constants and used them to download the score file from Xmader's dataset.

Other approaches were considered:

• Create a native Python interpreter just to decode the musescore js (like Js2py). (Will problably break with every API change.)
• Use a headless JS browser with Selenium. (Resource-heavy, not really cross-platform.)
• Run a JS engine like PyMiniRacer/PyQt5. (Better speed, but needs C extensions.)

So I decided to roll with the IPNS dataset.

Hacking

All my python projects now use flit to build and publish. So you need to python3 -m pip install flit first.

flit build

Install

(python3 -m) pip install musdl

Optionally, to export the score in other formats (midi, mp3, etc.) install musescore. musdl relies on its command-line tool mscore to export scores:

# Linux
sudo (package manager/snap) install musescore
# Windows
scoop bucket add extras  # add the extras bucket if you haven't
scoop install musescore
