Converting into another concept may need context this value does not carry (a root, an octave, a key). Where it is missing the library assumes a default and says so; where a step drops information it is listed.

• Pitch-class set sequence · Pitch-class sets in order

  lossy
  2-9

  Path chord-sequence → pc-set-sequence

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.

• Pitch-class set · Pitch-class numbers

  lossy
  2-9

  Path chord-sequence → pc-set-sequence → pc-set

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.

  D5

  Path chord-sequence → pc-set-sequence → pc-set → chord

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.
  • Drops interpretation. 2-9 is named D5, a detection rather than a spelling.

• Note set · Letter names

  D4-A4

  Path chord-sequence → pc-set-sequence → pc-set → note-set · needs root, octave

  • Assumed root C. No root was given, so the value is read from C.
  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.

• Pitch-class distribution · Twelve weights

  lossy
  0,0,1,0,0,0,0,0,0,1,0,0

  Path chord-sequence → pc-set-sequence → pc-set → pc-space

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.

• Point set · Semitone offsets

  lossy
  2-9

  Path chord-sequence → pc-set-sequence → pc-set → point-set

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.

• Set class · Forte name

  lossy
  2-5

  Path chord-sequence → pc-set-sequence → pc-set → pc-set-analysis

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.

• Grid position · Cells col,row (optional layout@origin: prefix)

  lossy
  aura@C3:2,2 3,3

  Path chord-sequence → pc-set-sequence → pc-set → note-set → grid-position · needs root, octave, layout

  • Assumed root C. No root was given, so the value is read from C.
  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Assumed layout aura. No layout was given, so positions are read on the aura layout.
  • Assumed root C3. No root was given, so the value sounds above C3.
  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.
  • Drops alternative positions. A4 has 2 positions on aura; the one nearest (0, 0) is kept.

• Note distribution · MIDI : weight pairs

  lossy
  62:1,69:1

  Path chord-sequence → pc-set-sequence → pc-set → note-set → note-space · needs root, octave

  • Assumed root C. No root was given, so the value is read from C.
  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.

• Pitch class · Pitch-class number

  lossy
  2

  Path chord-sequence → pc-set-sequence → pc-set → chord → pitch-class

  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.
  • Drops interpretation. 2-9 is named D5, a detection rather than a spelling.
  • Drops quality, bass. A chord symbol's root.

• Note · Letter name

  lossy
  D4

  Path chord-sequence → pc-set-sequence → pc-set → chord → pitch-class → note · needs octave

  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops root function, spelling, bass, N.C.. Each chord's pitch classes, in order; N.C. becomes the empty set.
  • Drops order, duration, chord boundaries. A progression collapses to the union of its pitch classes.
  • Drops interpretation. 2-9 is named D5, a detection rather than a spelling.
  • Drops quality, bass. A chord symbol's root.
