CMME (Computerized Mensural Music Editing)
The idea of CMME, conceived in 1999 as a Princeton undergraduate project by Ted Dumitrescu, was to support dynamic editions based on encoding standards comparable with the most rigorous printed editions. Editions of music in mensural notation have given rise to many changes of editorial opinion. In contrast to print, virtual editions have the possibility of being easily re-rendered to express changing views. On-screen views support the presence or absence of musica ficta and text underlay rationalized to fit the music or clustered at the start of line (as in many period manuscripts). Marnix van Berchem is the current director of the Utrecht-based project.
KernScores is a comprehensive website of musical data for analysis. (Kern is the Common Western Notation encoding format the Humdrum ToolKit, which has its own website and data repository at Ohio State University.) KernScores emphasize piano music. A large number of analytical conversions can be run on-the-fly from the long list of links that follows each title listing. Most repertories are for keyboard. The full collection can be browsed here. (EsAC data has also been translated to the Kern format, and 1000 additional pieces have been added by Damien Sagrillo.) An online Humdrum editor enables users to add their own data and run simple analysis routines on it.
The following conversions of data to sound and notation are among those supported:
- MIDI (sound)
- MuseData (notation, editing, analysis)
- MusicXML (data interchange)
- ABC+ (notation)
- Guido (online notation)
MuseData, based at the Center for Computer Assisted Research in the Humanities at Stanford University, refers to (1) an encoding system for music, (2) the software optimized for it, and (3) several corpora of scores encoded in the system. The representation system and software have been developed with Walter Hewlett from 1984 through the present. The system is described in Beyond MIDI.
The musical corpora contain more than 1,200 fully encoded works, including symphonies, string quartets, operas, oratorios, cantatas, and other kinds of works. The names of encoders and musical sources are embedded in the files together with other metadata. A large number of works have been encoded by Frances Bennion and Edmund Correia Jr. Other contributions have been made by Jean-Pierre Dautricourt, Pamela Decker, Michael Flexer, and Steve Rasmussen. The web interface and data conversion are principally the work of Craig Sapp (also the site manager), with contributions by David Huron and Andreas Kornstaedt.
Mensural extensions by Hewlett have been adopted by the Josquin Research Project and the Tasso Music project (online in 2016). MuseData supports conversion to MIDI, Humdrum Kern, SCORE, MusicXML, and MEI. Direct conversion from MuseData code to PDF is under development.
