Leveraging Ajax, the DOM and Lilypond for a web-based notation editor, from the latest edition of the Lilypond Report.
The article discusses OMET:
OMET, an acronym for Online Music Editing Tools, is a project to develop a group of web-based applications for creating professional-quality music manuscripts.
Basically, this is a browser-based GUI Lilypond editor. Very, very cool.
Right now it's limited to guitar scores – though nobody should take that to mean notating guitar music is a simple task, given all the resources of the instrument. Add to that the nature of polyphonic music notation on a single staff and, well, "issues" arise.
I signed up for this project's mailing list to keep up-to-date with its progress.
BTW: Is that Fernando Sor's Opus 6, #6 I see in the article's screenshot?--------------
