Blues soloing — phrasing first, scales second
Nobody ever moved a room with a scale. Blues soloing is a language of two-bar sentences, bent notes that live between the piano keys, and the discipline to leave space. Here is the vocabulary in the order it actually matters.
1. Call and response — the sentence structure
The solo inherits the AAB shape of the lyric. Play a short phrase (the call), let it breathe, then answer — by repeating it with one note changed, or resolving it somewhere new. A 12-bar chorus comfortably holds three sentences. Listen to B.B. King on Live at the Regal: he sings a line, Lucille answers. That conversation is the whole art.
2. The two pentatonics — and the mix
Minor pentatonic (1–♭3–4–5–♭7) is grit; major pentatonic (1–2–3–5–6) is sweetness. The masters live in the blend — B.B. and Albert King pivot constantly over the I, then lean minor on the IV. A reliable rule while you build the ear: major-lean on the I, minor-lean on the IV and V. The "blues scale" is just minor pentatonic plus a chromatic ♭5 — seasoning to pass through, never to sit on.
3. Blue notes — playing between the frets
The defining pitches — ♭3 and ♭7, plus the ♭5 — are sung and bent sharp of flat: a ♭3 nudged a quarter-tone toward the major 3rd is the most blues-sounding note there is. On guitar that's the curl: bend the ♭3 up just shy of the 3. Keyboards fake it by crushing ♭3 into 3. This microtonal territory is why the blues can't be fully written down — it must be copied by ear.
4. The B.B. box — one position, infinite mileage
B.B. King spent a career inside a four-fret box around the root on the B string (in A: frets 8–11 on the top strings). It puts the root under the index finger, the 2nd ready to bend to the 3rd, the 6th and ♭7 a finger apart — sweet and sour side by side. Learn it in A, then move it. The box teaches the central truth: where you can sing, you can play.
5. Following the changes (or deliberately not)
Two honest approaches. Down-home: one scale over the whole form, the band's harmony supplies the tension. Uptown (T-Bone Walker onward): target chord tones — land the 3rd of each chord as it arrives (C♯ over A7, F♯ over D7, G♯ over E7). Practise uptown even if you prefer down-home: knowing where the 3rds live is what makes one-scale phrasing land on purpose instead of by luck.
6. Dynamics, space, repetition
- Space: the rests are part of the phrase. Albert Collins silenced rooms with what he didn't play.
- Repetition: one lick repeated three times builds more heat than three different licks. The audience wants to anticipate.
- Dynamics: start a chorus quiet. You can't build from loud.
- Vibrato: the signature under everything — B.B.'s butterfly, Albert King's slow moan. Develop yours on one long note a day.
