Shape 1 is the 5th fret box. Shape 2 is the 7th-10th. The other three shapes complete the map.
A minor pentatonic, shape 3 (10th fret)
A minor pentatonic, shape 4 (12th fret)
A minor pentatonic, shape 5 (15th fret)
Shape 5 wraps back to a higher-octave shape 1. All five shapes are the same notes (A, C, D, E, G), just at different positions on the neck.
How the shapes overlap
Each shape shares its first and last frets with the neighboring shape. Visualize:
fret: 5 7 8 10 12 13 15
shape: [1][1 +2][2 +3][3 +4][4 +5][5]
Slide between shapes through the overlap notes. The whole neck is one connected scale.
The 12-bar blues challenge
Practice metronome
80BPM
Loop a 12-bar blues in A backing track. Solo using one shape per chorus:
- Chorus 1: shape 1
- Chorus 2: shape 2
- Chorus 3: shape 3
- Chorus 4: shape 4
- Chorus 5: shape 5
Where this leads
Once the five shapes connect, you stop playing "shapes" and start playing the scale. You think melodies, not positions. That is the transition to advanced playing. It takes months.For now: just play the shapes. The pattern recognition will follow.
Next: the Mixolydian mode. One more note added to pentatonic, a whole new sound.
