D Blues Scale on guitar
The blues scale is just the minor pentatonic scale with one extra note added: the "blue note" (a flatted 5th). This adds that classic bluesy tension.
The notes of D Blues Scale
Built on D, the scale degrees spell out like this. The degree is the number you would call that note relative to D:
RiffRoute writes every accidental as a sharp. A sharp and the flat above it are the same fret, so A♯ is B♭ and so on.
Where it lands on the fretboard
Every fret from the open string up to the 12th that belongs to the D Blues Scale, string by string. Root notes are highlighted.
- Low E: 1, 3, 4, 5, 8, 10
- A: 0, 3, 5, 8, 10, 11, 12
- D: 0, 3, 5, 6, 7, 10, 12
- G: 0, 1, 2, 5, 7, 10, 12
- B: 1, 3, 6, 8, 9, 10
- High E: 1, 3, 4, 5, 8, 10
Your anchor points: D is at fret 10 on the low E string and fret 5 on the A string. Start every pattern from one of those and you always know where home is.
Use the blue note as a passing tone. Don't linger on it too long or it will sound dissonant!
