A parser for MuseScore files, serving as data factory for annotated music corpora.
Project description
ms3 - Parsing MuseScore 3 and 4
Welcome to ms3, a Python library for parsing MuseScore files.
Statement of need
Here comes a list of functionalities to help you decide if this library could be useful for you.
parses MuseScore 3 and 4 files, dispensing with lossy conversion to musicXML. The file formats in question are
uncompressed *.mscx files,
compressed *.mscz files,
extracts and processes the information contained in one or many scores in the form of DataFrames:
notes (start, duration, pitch etc.) and/or rests,
measures (time signature, lengths, repeat structure etc.)
labels, such as
guitar/Jazz chord labels
arbitrary annotation labels
expanded harmony labels following the DCML annotation standard
cadences (part of the same annotation syntax)
form_labels (annotation standard currently in press)
chords, that is, onset positions that have musical markup attached, e.g. dynamics, lyrics, slurs, 8va signs…
metadata from the respective fields, but also score statistics, such as length, number of notes, etc.
stores the extracted information in a uniform and interoperable tabular format (*.tsv)
writes information from tabular *.tsv files into MuseScore files, especially
chord and annotation labels
metadata
header information (title, subtitle, etc.)
note coloring
uses a locally installed or standalone MuseScore executable for
batch-converting files to any output format supported by MuseScore (mscz, mscx, mp3, midi, pdf etc.)
on-the-fly converting any file that MuseScore can read (including MuseScore 2, cap, capx, midi, and musicxml) to parse it
offers its functionality via the convenient ms3 commandline interface.

Installation
ms3 requires Python >= 3.10 (type python3 --version to check). Once you have switched to a virtual environment that has Python 3.10 installed you can pip-install the library via one of the two commands:
python3 -m pip install ms3 pip install ms3
If successful, the installation will make the ms3 commands available in your PATH (try by typing ms3).
Quick demo
Parsing a single score
import ms3
score = ms3.Score('musescore_file.mscz')
Parsing a corpus
import ms3
corpus = ms3.Corpus('score_directory')
corpus.parse()
Parsing several corpora
import ms3
corpora = ms3.Parse('my_research_corpora')
corpora.parse()
Making Changes & Contributing
This project uses pre-commit to ensure code quality. If you are a developer, please make sure to install it before making any changes:
cd ms3 pip install -e ".[dev]" # includes "pip install pre-commit" pre-commit install
