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-A4

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

  • Note distribution · MIDI : weight pairs

    exact
    60:1,69:1

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

  • Pitch-class set · Pitch-class numbers

    lossy
    0-9

    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
    0-9

    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 distribution · Twelve weights

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

    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
    2-3

    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.
3 bridges exist but fail for this value

  • Chord symbol

    note-set→chord: Invalid note set as a chord: received "C4-A4", expected notes that name a chord

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

  • Pitch class

    note-set→chord: Invalid note set as a chord: received "C4-A4", expected notes that name a chord

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

  • Note

    note-set→chord: Invalid note set as a chord: received "C4-A4", expected notes that name a chord

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

Live coding

Use in Symbolic Cycle

sym('grid-position/chess/aura@C3:d1d4')

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