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
