THUNDERFRET

Fretboard Note Map — Learn Every Note Position

Pick a note — say, every G on the guitar — and the map lights all of them at once, colored by octave, on the neck and the piano together. Seeing the same note in its five or six homes, and seeing which of them are the same pitch versus an octave apart, is the fastest route to actually knowing the fretboard instead of counting up from the dots.

The map works for guitar, bass and ukulele, in any tuning, and there is a whole-neck view that colors every position by octave at once — useful for understanding why the same lick sounds higher on the thin strings even at the same fret. Pair it with the name-the-note drill in Practice mode to turn recognition into recall.
