downgrade (line 181)

Orders the chords resulting from the four possible second steps of the most dissonant tone, from low to high dsg

  • return: array with the most dissonant tone and four possible chords resulting from moving it
array downgrade (array $chordrec, array $exceptpitchset)
  • array $chordrec: array representing a chord structure
  • array $exceptpitchset: array of pitches to be ignored by the findpmaxcontrib function
extractset (line 75)

  • array $chordrec: array representing a chord structure
psmdissrec (line 277)

Increases an analyzed chord's dissonance, using parallel subset motion

  • return: chord with increased dissonance
array psmdissrec (array $chordrec)
  • array $chordrec: array representing a chord structure
targetrecto (line 23)

Changes dissonance of a chord in the direction of the supplied target dissonance

  • return: changed chord structure
array targetrecto (array $chordrec, int $targetdiss)
  • array $chordrec: array representing a chord structure
  • int $targetdiss: target dissonance
upgrade (line 229)
