Keynote Bio

Craig is a researcher at the Packard Humanities Institute/Center for Computer Assisted Research in Humanities, as well as an adjunct professor at Stanford University. He has a Ph.D. in Computer-based music and acoustics from Stanford, a Master's in composition and piano performance as well as an undergraduate degree in music and physics from the University of Virginia. He has taught at Peabody Conservatory in Baltimore, Maryland, and worked on computational performance analysis of Chopin's mazurkas at Royal Holloway, University of London with Nicholas Cook. Currently he is working on a digital edition of Chopin's early prints at the Fryderyk Chopin Insitute in Warsaw, Poland. He is also technical director of the Josquin Research Project (, and the Tasso in Music Project (


Verovio Humdrum Viewer (VHV, is a web interface that integrates verovio ( and humlib ( into an online music notation editor and music-analysis interface. Music can currently be imported into VHV as Humdrum or MusicXML data, with MEI data import planned in the near future. The VHV interface allows for both textual and graphical editing of the music, as well as a system for applying analysis filters to the digital scores. VHV is currently being used for displaying music for the Tasso in Music Project ( and for several online analysis tools in the Josquin Research Project (, as well as being used for a planned critical edition of early Chopin music prints at The Fryderyk Chopin Institute in Warsaw, Poland. Recent work this summer on VHV has been to integrate real-time data validation, both in terms of basic data structure as well as the rhythmic content, and syntax highlighting. These features allow for faster editing and proof reading of the music.
