Overview

About

Maintained by Renfei MaoFirst published 2021-03-233 releasesCRAN page ↗GitHub ↗

Provides a simple and intuitive high-level language for music representation. Generates and embeds music scores and audio files in 'RStudio', 'R Markdown' documents, and R 'Jupyter Notebooks'. Internally, uses 'MusicXML' https://github.com/w3c/musicxml to represent music, and 'MuseScore' https://musescore.org/ to convert 'MusicXML'.
