Slow blues is counted in four, but every beat is split into three: "ONE-and-a, TWO-and-a". That gives twelve pulses per bar, which is why it's called 12/8. The feel is heavy and patient, like a slow walk.
This lesson is in A. You use the same two-string shapes as the shuffle: open A with the D string at fret 2 (fifth) and fret 4 (sixth), open D with the G string at frets 2 and 4, open low E with the A string at frets 2 and 4. The difference is that every note of the triplet is played, three strokes per beat, all equal.
Picking
- Downstrokes only. At these tempos you have time, and the sound is fuller.
- Palm-mute lightly. Lift the palm a little on beat one of each bar for a touch of accent, marked > in the tab.
- Index on fret 2, ring on fret 4.
It should sound like a slow, rolling wave: one-two-three, one-two-three, never rushing.
The most common mistake is turning the triplets into a shuffle (long-short) or speeding up. Every triplet is the same length. Tap your foot on the beat and say "one-and-a" out loud.
How to practice
Start at 45 bpm. Stay on the first exercise until the pulse is completely even, then add the changes.
