Di-Chord Pictograph System
Each glyph encodes all three Plogger sound factors simultaneously. Bracket shape = pulsation · Shadow direction = F/O factor · Color = harmonicity.
Bracket Shape — Pulsation
- ●Jagged / serratedDissonant · 8 Hz
- ●Smooth / roundedModal · 4 Hz
- ●Straight edgesPerfect · 2 Hz
Shadow Direction — F/O Factor
- ●← Shadow leftFundamental-referring
- ●→ Shadow rightOctave-referring
- ●↔ Both sides[6] Tritone
Color — Harmonicity
- ●Light shadeHarmonic · open · bright
- ●Dark shadeNon-harmonic · closed · dense
- ●Neutral gray[6] Tritone · equidistant
