A Minor Pentatonic - 3 Note Pattern

This lesson expands the familiar A minor pentatonic box shape (5-7-5-7-5-8-5-8) to include notes both lower and higher on the neck. The basic shape covers two octaves, but thinking more horizontally rather than vertically opens up far more of the fretboard.

What You'll Learn:

• What an octave means and why it's called that

• How to think parallel instead of vertical on the fretboard

• The lower extension using open E and G notes (frets 3 and 5)

• The higher extension - the "house shape" at frets 8-10

• How to visualize the house with a triangular roof

• Where your A root notes are located in the extensions

• The important connecting note at 9th fret string 3

• How to slide into the 9th fret position

• Why these extensions are the same notes as C major pentatonic

• How relative major and minor scales share the same notes

Understanding Octaves

The term "octave" comes from "eight" - like an octagon has eight sides. In the major scale, there are eight notes from A to A. The pentatonic scale only uses five of those notes, but the distance from one A to the next A is still called an octave.

Thinking Horizontally

Rather than thinking only vertically (staying in one position and moving across strings), thinking horizontally across the neck opens up new possibilities. This is similar to how the E minor pentatonic works - spreading out parallel to the frets rather than strictly perpendicular.

The Lower Extension

The lower extension includes the open E and G strings, plus notes at frets 3 and 5. The A note at the 5th fret of the low E string becomes the root note, and everything below that is part of the extended scale. This gives you access to a full extra octave without changing positions.

The House Shape

The higher extension is often called the "house shape" because it looks like a building with a triangular roof. Starting at the 8th fret (where the highest note of the basic shape sits), the pattern continues with four crucial notes between frets 8 and 10. This pattern exactly mirrors four notes from the lower position - it's the same shape moved up the neck. The root A notes appear at the 10th fret on string 1 and at the 8th fret on string 3.

Connecting the Positions

The 9th fret of string 3 (the last fret marker on most guitars) is a crucial connecting point. Sliding into this position from the basic box shape is a common move in solos. Once there, the 8-10-8-10 pattern takes over.

The C Major Connection

All these notes are identical to the C major pentatonic scale, because A minor and C major are relative scales - they share all the same notes. The only difference is which note you emphasize as the root. Understanding this relationship is key to seeing how different scales overlap on the fretboard.
