Bass Fretboard Notes Chart (4 and 5-String)
Quick answer
On a 4-string bass the open strings are E, A, D and G. Each fret raises the note by a half step, and at the 12th fret the notes repeat one octave higher. Learn the natural notes (no sharps) on the E and A strings first; most root notes in beginner songs are there.
4-string bass, frets 0-12
Bright dots are natural notes; darker dots are sharps (also called flats: C# is the same note as Db).
5-string bass (low B added)
Natural notes only
Shortcuts that make it stick
- No sharp between B-C and E-F. Every other pair of natural notes has a sharp between them.
- The 5th-fret rule. The 5th fret of a string is the same note as the next open string up (E string 5th fret = A).
- Octave shape. Two strings up and two frets up is the same note an octave higher (E string 3rd fret G = D string 5th fret G).
- 12th fret. Same names as the open strings, one octave up. Fret markers at 3, 5, 7, 9 and the double dot at 12 help you find your place.
A five-minute drill
- Pick one note, such as C.
- Find it on the E and A strings, then on D and G.
- Say the name aloud each time you play it.
- Check yourself with the bass note finder, which highlights every place a note appears.
Safety notes
- Stop and rest if your hand, wrist or forearm aches; tension is the usual cause.
- Keep amp and headphone volume low to protect your hearing.
