Chicago blues

History and character

Chicago blues is the urban electric blues that emerged in Chicago with the Great Migration of African Americans from the South to the industrial cities of the North in the first half of the twentieth century. By the 1930s the city already had a blues scene (the “Bluebird sound” of the Bluebird label with Tampa Red, Big Bill Broonzy, and Sonny Boy Williamson I; clubs such as Ruby Lee Gatewood's “The Gates”); in the early 1940s the Mississippi bluesmen arrived, bringing Delta blues and amplifying it so they could be heard in the noisy clubs of the South Side. Muddy Waters, who arrived in 1943 and was welcomed by Big Bill Broonzy, scored his first electric hit with “I Can't Be Satisfied” (1948) and recorded “Rollin' Stone” (1950), which gave its name to the Rolling Stones and to Rolling Stone magazine.

The peak came between the late 1940s and the early '50s with Chess Records (and its subsidiary Checker), run by brothers Leonard and Phil Chess: Muddy Waters (“Hoochie Coochie Man,” 1954, and “I Just Want to Make Love to You,” both written by Willie Dixon, bassist, songwriter, and producer for Chess), Howlin' Wolf (“Smokestack Lightnin',” “Spoonful”), Little Walter (who put the amplified harmonica at the center of the sound: “Juke,” 1952), Sonny Boy Williamson II, Jimmy Rogers, Elmore James (the slide of “Dust My Broom”), Jimmy Reed, and Otis Spann on piano. It was Muddy Waters who, in 1955, pointed Chuck Berry toward Chess.

From the mid-1950s the West Side sound (Otis Rush, Magic Sam, Buddy Guy, on labels such as Cobra) brought a sharper blues, with B.B. King–style lead guitar and jazz and soul influences, compared with the rawer, more aggressive South Side. In the late '50s and '60s Chicago blues reached an international audience (Sonny Boy Williamson II's English tours in 1963–64 with British groups); in the '70s Bruce Iglauer's Alligator Records documented the new generation (Hound Dog Taylor, Koko Taylor, Son Seals, Lonnie Brooks); the Chicago Blues Festival has been held since 1984. The typical lineup: vocals, one or two electric guitars (solid body), amplified harmonica, piano, bass, drums.

Scales and keys

Blues scale and minor pentatonic

• Minor pentatonic: 1 b3 4 5 b7. On A: A C D E G.
• Blues: 1 b3 4 b5 5 b7. On A: A C D Eb E G.
• Characteristic note: b3 bent toward the 3, with b7 and b5 as passing tones.
• Use: unison riffs for guitar, bass, and harmonica (Hoochie Coochie Man), solos, vocals.
• Real-world example: Muddy Waters — Mannish Boy (one chord, riff on the A pentatonic).
• Common mistakes: playing the scale without the vibrato and bends that make it “vocal.”

Major-minor blend

• Formula: 1 2 b3 3 4 b5 5 6 b7. On A: A B C C# D Eb E F# G.
• Use: West Side soloists (Otis Rush, Buddy Guy, Magic Sam) move from the minor pentatonic to the major depending on the chord: C# over A7, F# over D7.

Major pentatonic

• On A: A B C# E F#. Use: “sweet” B.B. King–style phrases in the West Side style, harmonica answers in first position.

Harmonica: the positions

• Second position (cross harp): a D harmonica for a blues in A; the resulting scale is a Mixolydian (A B C# D E F# G), with the b3 and b5 obtained through bends.
• Third position: a G harmonica for a blues in A → Dorian (A B C D E F# G), used for minor blues.
• Use: Little Walter, Big Walter Horton, Junior Wells, James Cotton.

Mixolydian

• On A: A B C# D E F# G. Use: rhythm guitar boogie riffs (1–3–5–6–b7), bass and piano lines.

Dorian (minor blues)

• On A: A B C D E F# G. Use: West Side minor blues (Otis Rush — “Double Trouble,” Magic Sam).

How to choose

Harmony

Form and function

12-bar blues (I7–IV7–V7), often with stop-time in the verses (the band plays a single hit on the one and the vocalist sings alone: Hoochie Coochie Man), one-chord tunes with a hypnotic riff (Mannish Boy, Smokestack Lightnin'), 8-bar blues, and minor blues (especially on the West Side).

Typical elements

• Unison riff for guitar, bass, and harmonica that serves as the “chorus.”
• Stop-time with hits from the whole band.
• Turnaround I7–IV7–I7–V7 with the descending lick.
• Ninth chords on the rhythm guitar (A9, D9, E9).
• Piano filling with triplets and inverted chords.

Harmonic rhythm

Slow and predictable; the tension is in the voice, the stops, and the interplay.

Voicings

Rhythm guitar with boogie patterns (fifth–sixth) or ninth chords; two guitars interweaving (Jimmy Rogers with Muddy Waters); piano with broken chords and triplets.

Typical progressions

Rhythm and groove

Feel

Triplet shuffle (the most common), slow blues in 12/8, one-chord tunes with an ostinato groove (often with displaced accents), rumba blues (Otis Rush, Magic Sam: straight eighth notes with a Latin figure), boogie and straight eighth notes in later blues.

Backbeat and drive

Drummer Fred Below (with Little Walter and at Chess) is considered one of the first to give Chicago blues a modern backbeat and a “clean” shuffle: loud snare on 2 and 4, ride/hi-hat shuffle, light kick.

Stop-time and hits

The stops are part of the rhythm: the whole band hits the one (or the one and the & of 2) and leaves the voice alone.

Microtiming

A “heavy” groove, behind the beat; harmonica and lead guitar push ahead and lag behind freely.

Drums

Principle

Chicago blues drumming keeps a solid shuffle and a firm backbeat, supports the stops and hits, and leaves room for vocals and harmonica. Drummers: Fred Below, Odie Payne, S.P. Leary, Francis Clay, Earl Phillips (Jimmy Reed), Sam Lay, Willie “Big Eyes” Smith.

Shuffle

• Hi-hat (or ride) in shuffle triplets (first and third triplet), accent on the quarter notes.
• Snare on 2 and 4, loud; sometimes the left hand adds the third triplet (double shuffle).
• Light kick on all four beats or on 1 and 3.

Slow blues

Triplets on ride or hi-hat, full snare on 2 and 4, kick on 1 and 3; triplet fills on the toms at the end of the chorus.

One-chord tunes

Ostinato groove with accents on the band's hits (Mannish Boy: hits on the one and on the “a” of 2, locked in with the guitar and vocal).

Dynamics

Verses quiet, harmonica and guitar solos louder; stop-time with crisp hits.

Interaction

The bass (upright or electric) and kick are one block; the drums follow the leader's cues and the stops.

Sections

Intro (often the riff or a turnaround), verses with stop-time, harmonica solo, guitar solo, final verse, tag.

Fills

Short, in triplets, at bar 12 or before the solos.

Sounds

1950s kit with a muffled 22" kick, a deep snare with snares engaged, dark ride; recorded with few microphones (Chess used a “chamber” echo in the studio's bathroom/basement).

Typical mistakes

Uneven shuffle, too many cymbals, modern rock drumming, missing the stops.

Bass

Sound

Upright bass (Willie Dixon) until the mid-1950s, then Fender electric bass (Precision); a round, deep, short sound.

Lines

Boogie (1–3–5–6–b7), walking shuffle, unison riffs with guitar and harmonica (Hoochie Coochie Man, Smokestack Lightnin'), pedal tones on one-chord tunes.

Relationship with the kick

Unison on the strong beats; the bass carries the shuffle triplet.

Examples

Willie Dixon (Chess), Calvin “Fuzz” Jones (Muddy Waters band), Dave Myers (with Little Walter), Bob Stroger.

Harmonic instruments

• Electric guitars (solid body and semi-hollow: Telecaster, Les Paul, Gibson ES): lead guitar with slide (Muddy Waters, Elmore James) or single notes (Buddy Guy, Otis Rush); rhythm guitar with boogie patterns and ninth chords (Jimmy Rogers, Hubert Sumlin with Howlin' Wolf).
• Amplified harmonica (Little Walter, Big Walter Horton, Junior Wells, James Cotton): played with a “bullet” microphone (Shure Green Bullet, Astatic) into a small, saturated tube amp: it is both a solo instrument and a “horn section.”
• Piano (Otis Spann, Pinetop Perkins, Sunnyland Slim): triplets, boogie, fills, inverted chords.
• Organ and horns in later productions and in soul blues.

Melody and vocals

Vocals

Powerful, rough voices (Muddy Waters as an “authoritative” baritone, Howlin' Wolf with his growl and falsetto, Koko Taylor), preacher-style singing, AAB lyrics with repeated “slogan-like” phrases; lots of interaction with harmonica and guitar.

Call and response

The voice sings 2 bars, the harmonica or guitar answers for 2.

Solos

Amplified harmonica (long, sustained phrases, bends, rhythmic “chugging”), slide or single-note guitar, piano.

Effects

Slapback and chamber echo on the voice (the Chess sound), saturated amps for harmonica and guitar.

Instruments

• Vocals
• 1–2 electric guitars (also slide)
• Amplified harmonica (bullet mic + tube amp)
• Piano
• Upright bass, later electric bass
• Drums
• Sax and organ (in some bands)

Drum patterns

Synths and sounds

• Piano V — Otis Spann–style piano: Bright upright with a bit of “honky-tonk,” triplets and boogie; small room.
• B-3 V — Organ: 1960s–'70s Chicago blues and soul blues: drawbars 888000000, slow Leslie, overdrive.
• Wurli V — Wurlitzer: A “juke joint” color as an alternative to the piano.

Song structure

Form

• Intro (4 bars or an instrumental chorus, often with the riff).
• Verses of 12 bars (2–3), often with stop-time.
• Harmonica solo (1–2 choruses).
• Verse.
• Guitar or piano solo (1–2 choruses).
• Final verse and tag (turnaround and stop on the V7 or a final hit).
• Length 2:45–4:00 (Chess singles); longer live.

Arrangement

A compact band that plays “together”: verses with restrained dynamics and stops, solos with the band louder, last chorus at maximum energy; many tunes end with a fade on the riff.

Mixing and mastering

Sonic goal

A band in a room, saturated and alive: vocal and harmonica up front, raw guitars slightly distorted by small amps, deep bass, drums with a crisp backbeat, chamber echo or slapback.
