Notes on the Fretboard

Start with the open strings

Standard tuning, thickest string to thinnest, is E A D G B E. Those are your anchors. Every fret you move up is one semitone (one half-step), so from any open string you can count your way to any note. Master the note names on the low E and A strings first — most chord roots live there, so it pays off immediately.

The 12th-fret reset

Here's the shortcut that halves the work: the neck repeats at the 12th fret. Fret 12 on any string is the same note as the open string, one octave higher. So once you know frets 0 to 11, you already know 12 to 24 — they're the same names again.

Octave shapes — find notes by pattern

Rather than counting frets every time, guitarists use octave shapes. From a note on the low E string, the same note lives two strings up and two frets across(on the D string). These little shapes let you leap around the neck and instantly name notes you haven't memorised, using ones you have as reference points.

Naturals, sharps and flats

There are only seven natural notes (A B C D E F G); the frets in between are the sharps and flats. Two pairs have no note between them — B–C and E–Fare only one fret apart. Knowing those two "no-sharp" gaps stops the most common fretboard mistakes.

The single fastest way to learn this is to see it. In the interactive tool, use Map and Explore to click any fret, hear the note, and watch the same pitch appear elsewhere on the neck and on the piano. Then sharpen it with the "Name the Note" drill. Next up: intervals and scales.
