• Chord quality without a root

  Invalid chord degrees: received [0,6,10,13,17,20,24,27], expected degrees a chord symbol can name (root, third, fifth, sixth, seventh, 9, 11, 13 and their alterations)

• Scale type without a tonic

  Invalid point set as a scale type: received [0,6,10,13,17,20,24,27], expected offsets 0–11 that form a named scale

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-Gb4-Bb4-Db5-F5-Ab5-C6-Eb6

  Path point-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.

• Pitch-class set · Pitch-class numbers

  lossy
  0-1-3-5-6-8-10

  Path point-set → pc-set

  • Drops octave placement, doubling. Offsets fold into the octave above the root.

• Chord symbol · Chord symbol

  Gbmaj13#11/C

  Path point-set → note-set → chord · 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 octave, voicing. C4-Gb4-Bb4-Db5-F5-Ab5-C6-Eb6 is named Gbmaj13#11/C; register and voicing are dropped.

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

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

  Path point-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 alternative positions. C4 has 2 positions, Gb4 has 2 positions, Bb4 has 2 positions, Db5 has 2 positions, F5 has 2 positions on aura; the one nearest (0, 0) is kept.

• Note distribution · MIDI : weight pairs

  exact
  60:1,66:1,70:1,73:1,77:1,80:1,84:1,87:1

  Path point-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.

• Pitch-class distribution · Twelve weights

  Path point-set → pc-set → pc-set-analysis

  • Drops octave placement, doubling. Offsets fold into the octave above the root.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.

• Pitch class · Pitch-class number

  Path point-set → note-set → chord → pitch-class · 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 octave, voicing. C4-Gb4-Bb4-Db5-F5-Ab5-C6-Eb6 is named Gbmaj13#11/C; register and voicing are dropped.
  • Drops quality, bass. A chord symbol's root.

• Note · Letter name
