Partitura Organum is a growing collection of organ music editions. The aim is to typeset lesser known organ music from original printed or manuscript sources that are in the public domain. The typesetting is done using LilyPond, an open source engraving program, and Frescobaldi, a dedicated editor for LilyPond.
The scores are released under the terms of the Creative Commons Attribution Non-commercial ShareAlike License, CC BY-NC-SA 4.0 International, which can be found at creativecommons.org. All scores come with a recording, made with the virtual instrument software Hauptwerk.
Allthough I review the scores and play them myself, a small error is easily made. And where a manuscript source is ambiguous or (in my opinion) incorrect, I provide a solution based on my knowledge of music theory and my own taste. These scores are not meant as “Urtext”-editions. However, any suggestions to correct errors are welcome.
