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.

• Note set · Letter names

  exact
  C4-Ab4-C5-Eb5-Gb5

  Path chord → note-set · needs octave

  • Assumed octave 4. No octave was given, so octave 4 is used.

• Pitch class · Pitch-class number

  lossy
  8

  Path chord → pitch-class

  • Drops quality, bass. A chord symbol's root.

• Pitch-class set · Pitch-class numbers

  lossy
  0-3-6-8

  Path chord → pc-set

  • Drops root function, spelling, bass. A chord symbol's pitch classes, with C as 0; which one is the root is forgotten.

• Point set · Semitone offsets

  lossy
  -8,0,4,7,10

  Path chord → point-set

  • Drops root pitch, spelling, compound degree octave placement. A chord symbol's intervals above its root, in close position; compound degrees fold modulo 12, with a slash bass below the root.

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

  lossy
  aura@C3:3,0 2,4 3,4 3,5 6,2

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

  • 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 alternative positions. C4 has 2 positions, Ab4 has 2 positions, C5 has 2 positions, Eb5 has 2 positions, Gb5 has 2 positions on aura; the one nearest (0, 0) is kept.

• Note · Letter name

  lossy
  Ab4

  Path chord → pitch-class → note · needs octave

  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops quality, bass. A chord symbol's root.

• Note distribution · MIDI : weight pairs

  exact
  60:1,68:1,72:1,75:1,78:1

  Path chord → note-set → note-space · needs octave

  • Assumed octave 4. No octave was given, so octave 4 is used.

• Pitch-class distribution · Twelve weights

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

  Path chord → pc-set → pc-space

  • Drops root function, spelling, bass. A chord symbol's pitch classes, with C as 0; which one is the root is forgotten.

• Set class · Forte name

  lossy
  4-27B

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

  • Drops root function, spelling, bass. A chord symbol's pitch classes, with C as 0; which one is the root is forgotten.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.
