Instrument setup
Adds a separately drawn and independently tuned fourth string. Default: D–A–D–D. In D–A–D–C, the C is below the neighboring D. Chord-shape lines are unavailable whenever four equidistant strings are on.

Choose your frets
Frets 6.5 and 13.5 begin on and may be switched independently. Other chromatic frets begin off.
12 fingerboards selected
Triad chord atlas
Root tones are filled and marked R. Every fretted circle sits just behind its fret. Additional chromatic fret lines appear in rust. Optional chord shapes are available only for approved three-string D–A–D, D–A–A, and D–G–D triads: learn the shapes, then forget the shapes.
