Scale helpers

Description

Helper functions for working with musical scales.

Usage

scale_diatonic(key = "c", collapse = FALSE, ignore_octave = FALSE)

scale_major(key = "c", collapse = FALSE, ignore_octave = FALSE)

scale_minor(key = "am", collapse = FALSE, ignore_octave = FALSE)

scale_harmonic_minor(key = "am", collapse = FALSE, ignore_octave = FALSE)

scale_hungarian_minor(key = "am", collapse = FALSE, ignore_octave = FALSE)

scale_melodic_minor(
  key = "am",
  descending = FALSE,
  collapse = FALSE,
  ignore_octave = FALSE
)

scale_jazz_minor(key = "am", collapse = FALSE, ignore_octave = FALSE)

scale_chromatic(
  root = "c",
  collapse = FALSE,
  sharp = TRUE,
  ignore_octave = FALSE
)

Arguments

key	character, key signature.
collapse	logical, collapse result into a single string ready for phrase construction.
ignore_octave	logical, strip octave numbering from scales not rooted on C.
descending	logical, return the descending scale, available as a built-in argument for the melodic minor scale, which is different in each direction.
root	character, root note.
sharp	logical, accidentals in arbitrary scale output should be sharp rather than flat.

Details

For valid key signatures, see keys().

Value

character
