The blues scale is the minor pentatonic plus one note: the flat five, or blue note, between the 4th and the 5th. Played as a passing note rather than a resting place, it gives blues and rock solos their grit. On the guitar it falls into 5 boxes. Box 1 starts on the root, frets 4-7. The root G♯ is at fret 4 on the low E string and fret 11 on the A string.

Strings from the low E (left) to the high E (right), frets numbered on the left. Magenta dots are the root, G♯. The tab under each diagram plays the position from its lowest note to its highest; play it back down the same way.
The boxes above are slices of this map. They overlap: the highest notes of one are the lowest notes of the next, so once you know two neighbours you can slide from one to the other along a string.
6 notes: G♯ B C♯ D D♯ F♯. In whole (W) and half (H) steps: W+H W H H W+H W. The half steps are where the scale gets its colour.
| Note | Degree | Interval from the root | Half steps | Fret on the low E string |
|---|---|---|---|---|
| G♯ | 1 | Root | 0 | 4 |
| B | b3 | Minor 3rd | 3 | 7 |
| C♯ | 4 | Perfect 4th | 5 | 9 |
| D | b5 | Diminished 5th | 6 | 10 |
| D♯ | 5 | Perfect 5th | 7 | 11 |

Take a minor pentatonic box you already know and add the flat five where it falls. Slide through it, 4 to flat five to 5, instead of stopping on it.
The minor pentatonic is the same scale without the flat five. Compare the two: G♯ minor pentatonic.
Set the tempo low, play each position up and down with the button above, then try it yourself at the same speed. Raise the tempo by 4 BPM only when it is clean.
Going up: G♯, B, C♯, D, D♯, F♯, then G♯ an octave higher. Its formula is 1 b3 4 b5 5 b7.
Start with box 1, frets 4-7: the root G♯ is under your finger 1 on the low E string. Play two notes on each string (three where the blue note falls), from the low E to the high E, then back down. The diagrams and tabs on this page show all 5 boxes.
On the low E string at fret 4, on the A string at fret 11. Those two root notes anchor most scale positions and barre chords.
The minor pentatonic is the same scale without the flat five.
