The development of GNU Solfege has moved to Savannah because email@example.com (main author) is stepping down as the only maintainer of the program. Please contact firstname.lastname@example.org if you want to take over the job. GNU Solfege is an ear training program written to help you train intervals, chords, scales and rhythms. It is free software and part of the GNU Project.

MusicXML MusicXML is an XML-based file format for representing Western musical notation. The format is proprietary, but fully and openly documented, and can be freely used under a Public License. History MusicXML was developed by Recordare LLC, deriving several key concepts from existing academic formats (such as Walter Hewlett's MuseData and David Huron's Humdrum). It is designed for the interchange of scores, particularly between different scorewriters.
