Fretboard Notes for a 4-String Bass Guitar

Standard Tuning (E-A-D-G)

A standard 4-string bass is tuned as follows (lowest to highest string):

• E (4th string, thickest)

• A (3rd string)

• D (2nd string)

• G (1st string, thinnest)

Fretboard Layout (First 12 Frets)

Each fret represents a half-step (semitone). The 12th fret is an octave above the open string.

Key Concepts

• Octaves:

  • Any note played on one string can be found an octave higher two strings up and two frets over. Example:

    • 5th fret of E string (A) → 7th fret of D string (A, one octave higher)

• 5th Fret Rule:

  • The note on the 5th fret of one string is the same as the open string below it, except for the G string.

  • Example: 5th fret of E string = A (same as open A string).

• Harmonics:

  • Natural harmonics exist at the 5th, 7th, and 12th frets. The 12th fret harmonic is an exact octave of the open string.

• Movable Patterns:

  • Since the bass follows a consistent tuning pattern, you can use scale and chord shapes in multiple places on the fretboard.
