Five frets shows only the stretch the notes sit in, and widens when they will not fit — a chord reaching from an open string to the ninth fret keeps both. Pages that already let you choose how much neck to see keep their own choice.
Applies wherever a note is simply named. Where the spelling is fixed by the music — the chords of a key, the notes of a triad — it stays as written.
The default already covers deuteranopia and protanopia; blue–yellow covers tritanopia, and high contrast drops colour altogether. Every dot is labelled and roots are filled, so the board never relies on colour alone.
Fret number, 1 to 24. Leave it empty for no capo. Notes behind the capo are hidden, since you can’t play them.
