Humdrum - Introduction What is Humdrum? A set of general-purpose music software tools, but free Encode, manipulate, and output a wide variety of musically-pertinent representations, created by Prof. David Huron Platform: Designed for UNIX, but cross-platform now. Humdrum Toolkit: more than 60 inter-related software tools 15% in C, 15% in kornshell, 2% in LEX lexical parser and YACC Most written in AWK (a fast prototyping language). Humdrum Syntax: ASCII (text) data Currently roughly 10,000 encoded works consistent with the Humdrum syntax -- most in the **kern representation.

Where to access Humdrum? Music encoded in Humdrum: CCARH CCARH (The Center for Computer Assisted Research in the Humanities) Founded in 1984, has encoded large databases of musical score information, current Director: Walter B. Hewlett engaged in the development of large databases of musical and textual materials for applications in research, teaching, and performance. MuseData (TM) databases : represent a major resource for music research. Availability: J.S. Bach, Chorale Harmonizations J.S. Bach, Brandenburg Concertos (Bach Gesellschaft edition) Archangelo Corelli, Trio Sonatas Antonio Vivaldi, Violin Concertos (including The Four Seasons) Essen Folk melody collection (more than 6,000 European folksongs) Who is using Humdrum Classifying Musical Textures: Complexity in Hadyn String Quartets
