A minor pentatonic on Bass

Also called: Aeolian Pentatonic

A minor pentatonic uses A, C, D, E and G. On bass, its root, fourth and fifth are useful landmarks for building short grooves and finding the same pitch in more than one position.

Notation details

A natural minor signature: no sharps or flats. Other alterations are marked on the notes.

The 8 below the clef indicates that Bass sounds one octave below these written notes. This example uses an octave close to the staff for easier reading, keeping the scale’s key and canonical spelling.

Find and hear notes

Flats and sharps can name the same pitch. Staff notes keep their canonical spelling.

Scale root: A. Square markers identify it across the neck.

Keyboard: use arrow keys to move between notes, then Enter or Space to play.

Understand the scale

Minor pentatonic uses 1, ♭3, 4, 5 and ♭7. Its five notes omit the second and sixth of natural minor; compare the three-semitone gaps with its two-semitone steps.

Each note has an interval measured from the root. The graph spaces notes by semitones (one fret each); the numbers between markers show the steps to neighboring notes. The final note is the root one octave higher.

How the fretboard repeats

Fret 12 has the same note name as the open string, one octave higher. The pattern repeats every 12 frets. Between E and F, and between B and C, there is one semitone; the other adjacent natural notes are two semitones apart.

Every neighboring pair of strings is a perfect fourth apart. Fret 5 on one string matches the next open string above it. This consistent tuning lets you move patterns across the neck without the guitar’s G-to-B adjustment.

Try this

  • Begin with open A, then C at fret 3 on A.
  • Play open D at the nut, then E at fret 2 on the D string, and G on the open G string.
  • Return to A at fret 2 on G. Keep each note even and let the root feel like home.
