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
    D4-F4-A4-C5-E5-G5-B5-D6

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

  • Chord symbol · Chord symbol

    lossy
    Fmaj13#11/D

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

    • Drops octave, voicing. D4-F4-A4-C5-E5-G5-B5-D6 is named Fmaj13#11/D; register and voicing are dropped.
  • Note distribution · MIDI : weight pairs

    exact
    62:1,65:1,69:1,72:1,76:1,79:1,83:1,86:1

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

  • Pitch-class set · Pitch-class numbers

    lossy
    0-2-4-5-7-9-11

    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
    0-3-7-10-14-17-21-24

    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
    5

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

    • Drops octave, voicing. D4-F4-A4-C5-E5-G5-B5-D6 is named Fmaj13#11/D; register and voicing are dropped.
    • Drops quality, bass. A chord symbol's root.
  • Pitch-class distribution · Twelve weights

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

    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
    7-35

    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
    F4

    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. D4-F4-A4-C5-E5-G5-B5-D6 is named Fmaj13#11/D; register and voicing are dropped.
    • Drops quality, bass. A chord symbol's root.

Live coding

Use in Symbolic Cycle

sym('grid-position/chess/aura@C3:c3c4d4d5e5e6f6f7')

The cells sound on the layout .layout() names (wicki-hayden, harmonic-table, janko …), with cell (0, 0) on .root().
