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.

Notes are named the way you have set them under Note names in Settings — sharps, flats, or both. Every interval below lands on one of these twelve.
Please choose a root note.
Add an octave to any of these and it becomes a compound interval, which is where a chord’s upper numbers
come from: a 9th is a 2nd an octave up, an 11th a 4th, a 13th a 6th. A raised or lowered degree can be written
as an altered interval too — the ♯5 of an augmented chord is an augmented 5th, the same eight
semitones as the minor 6th above, named for the fifth it was raised from.
Notes here are named by your own setting rather than by strict interval spelling, so none of them carries a
double accidental. Written strictly, a few intervals from a sharp or flat root would need one — an
augmented 4th has to be some kind of 4th, whatever that takes. It is the same fret either way, and the fret
is the useful half.
