Other concepts

Bridges

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.

• Chord symbol · Chord symbol

  lossy
  C/E

  Path note-set → chord

  • Drops octave, voicing. E3-C4-E4-G4 is named C/E (also Em#5); register and voicing are dropped.

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

  lossy
  aura@C3:1,0 3,0 4,0 4,1

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

  • 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, E4 has 2 positions, G4 has 2 positions on aura; the one nearest (0, 0) is kept.

• Note distribution · MIDI : weight pairs

  exact
  52:1,60:1,64:1,67:1

  Path note-set → note-space

• Pitch-class set · Pitch-class numbers

  lossy
  0-4-7

  Path note-set → pc-set

  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.

• Point set · Semitone offsets

  lossy
  0-8-12-15

  Path note-set → point-set

  • Drops root, register. A note set keeps its shape as offsets from its lowest note and forgets where it sits.

• Pitch class · Pitch-class number

  lossy
  0

  Path note-set → chord → pitch-class

  • Drops octave, voicing. E3-C4-E4-G4 is named C/E (also Em#5); register and voicing are dropped.
  • Drops quality, bass. A chord symbol's root.

• Pitch-class distribution · Twelve weights

  lossy
  1,0,0,0,2,0,0,1,0,0,0,0

  Path note-set → note-space → pc-space

  • Drops octave, register. Folds 128 MIDI bins into 12 pitch-class bins, keeping the weights.

• Set class · Forte name

  lossy
  3-11B

  Path note-set → pc-set → pc-set-analysis

  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.

• Note · Letter name

  lossy
  C4

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

  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops octave, voicing. E3-C4-E4-G4 is named C/E (also Em#5); register and voicing are dropped.
  • Drops quality, bass. A chord symbol's root.
