Fret & Fern · The Voicing Room
Form guitar chords as small harmony puzzles: choose exactly three or four distinct recipe notes, place the requested pitch in the bass and stay within a fretted-span limit. Eight complete voicing studies, 96 solver-enumerated answers, nearest-voicing nudges, undo, keyboard/touch controls, local keepsakes and synthesized plucked-string audio. Adapted theory, chord and tuning algorithms from Guitar Dashboard: https://github.com/mikehadlow/gtr-cof (MIT; 380 stars observed; updated April 28, 2026). Original GPT workbench and pearlescent picks bundled locally. Metadata tags: github-source, game.
