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.

• Note set · Letter names

  exact
  E3-C4-E4-G4-B4

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

• Chord symbol · Chord symbol

  lossy
  Cmaj7/E

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

  • Drops octave, voicing. E3-C4-E4-G4-B4 is named Cmaj7/E; register and voicing are dropped.

• Note distribution · MIDI : weight pairs

  exact
  52:1,60:1,64:1,67:1,71:1

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

• Pitch-class set · Pitch-class numbers

  lossy
  0-4-7-11

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

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

• Point set · Semitone offsets

  lossy
  0-8-12-15-19

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

  • 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 grid-position → note-set → chord → pitch-class · needs layout, root

  • Drops octave, voicing. E3-C4-E4-G4-B4 is named Cmaj7/E; register and voicing are dropped.
  • Drops quality, bass. A chord symbol's root.

• Pitch-class distribution · Twelve weights

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

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

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

• Set class · Forte name

  lossy
  4-20

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

  • 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 grid-position → note-set → chord → pitch-class → note · needs layout, root, octave

  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops octave, voicing. E3-C4-E4-G4-B4 is named Cmaj7/E; register and voicing are dropped.
  • Drops quality, bass. A chord symbol's root.
