  2. Encoding systems: Goals, Means, Syntax • Binary; time-ordered;var-length; score Types 0, 1] • MIDI: Sound • Event-based 2009 Eleanor Selfridge-Field

  3. Encoding systems: Goals, Means, Syntax • Binary; time-ordered;var-length; score Types 0, 1] • ASCII; score/spatially- ordered; var. no fields • MIDI: Sound • SCORE: Graphics • Event-based • Object-based 2009 Eleanor Selfridge-Field

  4. Encoding systems: Goals, Means, Syntax • Binary; time-ordered;var-length; score Types 0, 1] • ASCII; score/spatially- ordered; var. no fields • ASCII; fixed/expandable; part-ordered [=MIDI Type 1] • MIDI: Sound • SCORE: Graphics • MuseData: Core rep. • Event-based • Object-based • Event-based 2009 Eleanor Selfridge-Field

  5. Encoding systems: Goals, Means, Syntax • Binary; time-ordered;var-length; score Types 0, 1] • ASCII; score/spatially- ordered; var. no fields • ASCII; fixed/expandable; part-ordered [=MIDI Type 1] • ASCII; fixed/expandable; time- or score-ordered • MIDI: Sound • SCORE: Graphics • MuseData: Core rep. • MusicXML: interchange • Event-based • Object-based • Event-based • Attribute-based 2009 Eleanor Selfridge-Field

  6. Encoding systems: Goals, Means, Syntax • Binary; time-ordered;var-length; score Types 0, 1] • ASCII; score/spatially- ordered; var. no fields • ASCII; fixed/expandable; part-ordered [=MIDI Type 1] • ASCII; fixed/expandable; time- or score-ordered • ASCII; score-ordered but no spatial information [=MIDI Type 0]; selective attribute encoding permitted • MIDI: Sound • SCORE: Graphics • MuseData: Core rep. • MusicXML: interchange • **kern: Analysis data • Event-based • Object-based • Event-based • Attribute-based • Event-based 2009 Eleanor Selfridge-Field

  7. Humdrum: Goal and History Goal: encoding for analysis Inventor: David Huron Orientation: Context-free grammar • Adaptable to many repertories • Features and representations can be extended • Features can be minimized • Data content sometimes unpredictable 2009 Eleanor Selfridge-Field

  10. Singer's Humdrum Explorer (Win) 2009 Eleanor Selfridge-Field

  11. Uses of Humdrum Bret Aarden (2000): GPS-based localization of musical features Jane Singer (2000): Melodic analysis 2009 Eleanor Selfridge-Field

  12. Uses…. Veltman (2002) Accent in Palestrina 2009 Eleanor Selfridge-Field

  13. Humdrum Operations Unix-based Unix regular expressions (grep) Humdrum-specific File-manipulation commands (assemble, yank) Sound-management tools (record, perform) Pitch re-identification tools (frequency, cents) Duration and accent tools (beat, accent pos.) Melody tools (e.g. melodic intervals) Harmony tools (e.g. harmonic intervals) 2009 Eleanor Selfridge-Field
