The Definitive "Stormy Monday Changes": Chromatic Passing 9ths, Passing Diminished 7ths, and the Jazz ii-V Turnaround
The Allman Brothers Band transformed T-Bone Walker’s slow blues into the holy grail of jazz-blues guitar progressions. Instead of standard three-chord 12-bar blues, they introduce chromatic dominant 9th slides (Ab9 to G9), an indispensable passing diminished chord (C#dim7 connecting C9 to G9), and the legendary descending minor turnaround (Bm7 to Bbm7 to Am7 to D9#5) that turns Texas slow blues into soaring jazz sophistication.
Harmonic Progression (Roman Numerals)
I9 - IV9 - I9 - bII9 - I9 - IV9 - #IV°7 - I9 - iii7 - biii7 - ii7 - V7#5Step-by-Step Movement
- •G9 (I9) & C9 (IV9): Dominant 9th chords replacing harsh dominant 7ths with smooth, rounded jazz-blues warmth.
- •Ab9 (bII9): Chromatic half-step upper neighbor sliding smoothly into G9 on bar 3, establishing the swinging jazz-blues character.
- •C#dim7 (#IV°7): Passing diminished 7th connecting C9 to G9 with chromatic bass motion C → C# → D.
- •Bm7 - Bbm7 - Am7 (iii7 - biii7 - ii7): Chromatic descending minor turnaround that elevates the slow blues into bebop territory.
- •D9#5 (V7#5): Altered dominant chord delivering sharp resolution tension pulling back to the G9 tonic.
Voice Leading & Counterpoint
- ›The bassline and inner voices move in half-steps: C9 (C) → C#dim7 (C#) → G9/D (D), creating an irresistible forward pull.
- ›Duane Allman and Dickey Betts target chord tones during the turnaround rather than running generic blues scales.
- ›Slow 12/8 time (50 BPM) gives each note and microtonal vocal bend space to bloom with singing PAF sustain.

Key Techniques
Chromatic 9th Chord Slides
IntermediateSliding movable dominant 9th chord grips down a half-step on the offbeat to create smooth jazz voice leading
Uses chords:
Progression:
Chromatic slide over G9 - Ab9 - G9
Technique Tips:
- •Keep finger pressure light during the slide so the fingers glide effortlessly over the frets
- •Do not lift your fingers off the strings during the half-step slide
- •Mute the low 6th string with the tip of your middle finger
- •Use a medium-heavy pick (1.0mm) for warm, round chord attack without clickiness
- •Listen to T-Bone Walker's original 1947 recording to hear the stylistic origin of the slide
12/8 Slow Blues Comping
IntermediateCounting four triplet pulses per measure (1-and-a, 2-and-a, 3-and-a, 4-and-a) at an ultra-slow 50 BPM tempo
Uses chords:
Progression:
12/8 comping across G9 - C9 - C#dim7
Technique Tips:
- •Relax your shoulders and breathe deeply with the slow 12/8 pulse
- •Let the chord notes bloom and sustain rather than muting them prematurely
- •Coordinate with the bass player's walking bassline notes
- •Keep your chord volume lower than the lead guitar so the solo cuts clearly
- •Practice playing with minimal wrist tension to sustain the groove over long 8-minute performances
Vocal Microtonal Bends
AdvancedSlow, emotional string bends with wide finger vibrato emulating human vocal inflections and microtonal blue notes
Uses chords:
Progression:
Vocal bends over G9 - C9
Technique Tips:
- •Always back up your bending ring finger with your index and middle fingers for stability
- •Check your bent pitch against a reference fretted note to ensure absolute pitch accuracy
- •Do not bend with finger muscles alone—the power must come from rotating the wrist and forearm
- •Turn your guitar volume down slightly (to 8) for sweet overdrive that responds to touch dynamics
- •Listen to Duane Allman's second solo chorus on At Fillmore East for textbook vocal phrasing
