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.
Tap any note on a fretboard to hear it.
Choose a note and see every interval measured from it.
A♯ and B♭ are the same pitch but not the same note, and their intervals are spelled differently. Both are here.
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.
