Humdrum: Goal and HistoryGOAL: 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

Uses of Humdrum

Bret Aarden (2000): GPS-based localization of musical features

Jane Singer (2000): Melodic analysis


Uses….

Veltman (2002) Accent in Palestrina


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)
