History and character
The American South
Southern hip hop (or “Dirty South”) encompasses the scenes of Atlanta, Houston, Memphis, New Orleans, and Miami. In the '80s Miami bass is born in Miami (2 Live Crew, MC A.D.E.), derived from electro, with extremely long 808s and explicit lyrics. In Houston, Rap-A-Lot assembles the Geto Boys (“We Can't Be Stopped,” 1991), DJ Screw invents chopped and screwed (slowed-down and “cut up” tracks), and UGK of Port Arthur bring Texan accents and slang. In Atlanta the Dungeon Family (OutKast, Goodie Mob, the Organized Noize production team) combines played instruments, gospel, funk, and soul: OutKast's “Southernplayalisticadillacmuzik” (1994) and André 3000's line at the 1995 Source Awards (“the South got something to say”) mark the turning point. In New Orleans bounce (from the “Triggerman beat”) and the Cash Money and No Limit (Master P) labels dominate sales in the late '90s. In Memphis, Three 6 Mafia create a dark, hypnotic sound.
Crunk
Crunk is born in the early '90s between Memphis (the strip clubs, DJ Paul and Juicy J) and Atlanta; the term appears in the mainstream in OutKast's “Player's Ball” (1993). Lil Jon & the East Side Boyz (“Get Crunk, Who U Wit,” 1997) bring it to the clubs; “Get Low” (with the Ying Yang Twins, 2003) reaches No. 2 on the Billboard Hot 100, and Lil Jon, the “King of Crunk,” produces Usher's “Yeah!” and Ciara's “Goodies” (2004), which open the door to crunk&B. The brief season of snap music (D4L, Dem Franchize Boyz) follows, and then trap (T.I., “Trap Muzik,” 2003).
Aesthetics
Huge TR-808 basses, less sampling and more synths or played instruments, shouted call-and-response choruses, regional accents and slang, a club and party orientation; strong independent labels and early use of mixtapes.
Scales and keys
Natural minor (Aeolian)
- Formula: 1 2 b3 4 5 b6 b7 (2-1-2-2-1-2-2).
- Example in C#: C# D# E F# G# A B.
- Chords: C#m – D#dim – E – F#m – G#m – A – B (i ii° III iv v VI VII).
- Use: crunk synth riffs (2–4 note ostinatos), 808 basses, trap melodies.
Phrygian and harmonic minor
- Phrygian in E: E F G A B C D (b2 = F).
- Harmonic minor in D: D E F G A Bb C#.
- Use: Memphis (Three 6 Mafia) and crunk's “menacing” riffs; the leading tone of harmonic minor in Lil Jon's riffs.
Minor pentatonic and blues
- In G: G Bb C D F; blues G Bb C Db D F.
- Use: Dungeon Family guitars and organs, funk basses, sung hooks.
Major / Mixolydian (gospel and soul)
- Major in F: F G A Bb C D E; Mixolydian in F: F G A Bb C D Eb.
- Use: OutKast, UGK, Goodie Mob, and the soul/gospel of the South; “party” crunk uses major stabs (I–bVII).
How to choose
| Scene | Scale |
|---|---|
| Club crunk | Aeolian / harmonic minor, ostinato riffs |
| Memphis | Phrygian |
| Dungeon Family, UGK | pentatonic, soul major, Mixolydian |
| Miami bass | Aeolian with electro stabs |
| Snap | almost no harmony: a 2-note riff |
Harmony
Ostinatos
In crunk the harmony is a 1–2 bar synth ostinato (often on 2–4 notes: root, b3, b2 or leading tone) repeated throughout the track; the chords are implied.
Played instruments
OutKast and Organized Noize work with richer harmonies: soul, gospel, and funk progressions with sevenths, played guitars and organs.
Bounce and Miami
Minimal harmony: stabs, samples (“Triggerman,” the Showboys' “Drag Rap”), 808.
Harmonic rhythm
Very slow in crunk (one fixed riff), normal in the Atlanta soul scene (one chord per bar).
Voicings
Synth stabs in octaves and fifths (synthetic power chords), organs with gospel voicings, synth brass in triads.
Typical progressions
| Name | Key | Chords | Degrees | How to use it |
|---|---|---|---|---|
| Crunk ostinato | C# minor | C#m C#m | i i | One chord and a 3-note synth riff (C#, E, D#): Lil Jon-style club hypnosis. |
| Crunk with leading tone | D minor (harmonic) | Dm C#dim Dm Bb | i vii° i VI | The leading tone C# in the riff creates aggressive tension; synth lead with pitch envelope. |
| Memphis Phrygian | E minor (Phrygian) | Em F | i bII | The dark sound of Three 6 Mafia: piano or synth a half step apart. |
| Atlanta soul | Bb major | Ebmaj7 Dm7 Cm7 F7 | IV iii ii V7 | Soul progression played with guitars and organs (Organized Noize, '90s OutKast). |
| Party Mixolydian | G (Mixolydian) | G F | I bVII | Festive major stabs: crunk&B and Miami bass. |
| Southern gospel | Ab major | Db Eb Cm Fm | IV V iii vi | Gospel progression with organ: UGK, Goodie Mob, later Zaytoven. |
Rhythm and groove
By scene
- Miami bass: 125–135, straight TR-808 with a very long kick, fast hats.
- Crunk: 75–105, repetitive TR-808/909, double-hit kick, huge claps on 2 and 4, club energy.
- Snap: 70–80, finger snaps in place of the snare, minimalism.
- Chopped and screwed: slowed-down tracks (−5/−10% and beyond), with repetitions (“chops”) and scratching.
- Bounce: 95–105, Triggerman beat, call and response.
Flow
Shouted call and response (crunk), marked Southern accents, relaxed, dragging flow (UGK, Houston), fast (Twista is from Chicago but heavily listened to in the South; Three 6 Mafia with the '90s triplet flow, a forerunner of trap).
Drums
Kick
TR-808 (long) or TR-909 (punchy); crunk: double hit on 1 and 3 (steps 1, 3, 11, 13) or on 1 and the “and” of 1. Miami bass: a very long kick that acts as the bass.
Snare / clap
Huge, layered claps on 2 and 4 (crunk); snaps on 2 and 4 (snap); on 3 in trap.
Hi-hat
Eighth notes with an open hat on the last upbeat (crunk), fast sixteenth notes (Miami bass), rolls (Memphis and trap); in “Yeah!” the hats come in only on the choruses.
Percussion
808 cowbell, whistle, gang vocals as percussion (“Yeah!”, “OK!”, “What!”).
Interaction
The long 808 doubles the kick; the shouted chants land on the drum rests.
Sections
Verse with the basic drums, chorus with hats, stops on the shouted phrases, a crash at the start of every section.
Typical mistakes
Groove too complex: crunk lives on repetition; claps too weak.
Bass
- Long 808 (Miami bass, crunk, trap): very long decay, tuned, doubles the kick.
- Synth bass stabs (crunk): short, heavy notes on the root.
- Played electric bass (Dungeon Family): funk and soul.
- Notes: root and octave; little melody in crunk.
- Range: 30–60 Hz fundamental; harmonics via saturation for the clubs.
Harmonic instruments
- Synth stabs, leads with pitch envelope (crunk), ostinatos.
- Organ, electric guitars, Rhodes (Atlanta soul, UGK).
- Dark piano (Memphis), synthetic strings.
- Horns (bounce, sampled New Orleans brass bands).
Melody and vocals
- Vocals: shouted, call and response (Lil Jon “Yeah!”, “OK!”), gang vocals; relaxed flows and Southern accents; Memphis triplet flow.
- Hooks: chants of 2–4 repeated words, or sung R&B choruses in crunk&B (Usher, Ciara).
- Backing vocals: huge gang vocals, doubled and tripled.
- Effects: little processing; in chopped and screwed, slowed vocals pitched down.
Instruments
TR-808, TR-909, synths (stabs, leads, ostinatos), 808 bass, organ, electric guitar, electric bass, Rhodes, piano, cowbell, whistle, gang vocals, rap and R&B vocals.
Drum patterns
Synths and sounds
- OP-Xa V — Crunk lead and stabs: Bright saws with a short pitch envelope on the attack (+2/+5 semitones, 30 ms) and an HP at 100 Hz: the 'Yeah!'-style lead.
- Jup-8 V — Stabs and pads: Full-chord stabs in octaves for crunk and Miami bass.
- Korg MS-20 V — Aggressive lead and sirens: Resonant, distorted filter for shrill riffs and club FX.
- B-3 V — Southern gospel organ: Full drawbars and Leslie for OutKast, UGK, Goodie Mob.
- Mini V — 808 and synth bass: Triangle with long decay and pitch envelope for a playable 808; filtered saws for bass stabs.

Song structure
| Section | Bars | What happens |
|---|---|---|
| Intro | 4–8 | chant, synth riff |
| Hook | 8 | shouted chant, full kit |
| Verse 1 | 16 | basic drums, riff |
| Hook | 8 | |
| Verse 2 | 16 | |
| Hook | 8 | |
| Bridge / breakdown | 8 | “let me see you…”, dance instructions, stop |
| Hook / outro | 8–16 |
Club tracks 3:30–4:30, with breakdowns for dancing; remixes and chopped and screwed versions stretch everything out.
Mixing and mastering
Sonic goal
Made for clubs and cars: enormous 808, claps that “split,” wide shouted choruses, cutting synths. References: Lil Jon “Crunk Juice” (2004), Usher “Yeah!” (2004), OutKast “Aquemini” (1998) for the played sound, UGK “Ridin' Dirty” (1996). Balance: 808 −1/−3, clap −3, vocal 0, backing vocals −3, synth −5.
Kick / 808
HP 25 Hz; fundamental 40–55 Hz; click 3–4 kHz (909); saturation for harmonics at 100–200 Hz; mono; if kick and 808 are separate, sidechain 3–5 dB.
Clap
HP 200 Hz; body 250 Hz; crack 1.5–3 kHz; 4:1 compression, 4 dB; wide layering (±20); gated reverb or short plate (0.8 s) at −16 dB.
Hi-hat and percussion
HP 500 Hz; pan ±15; cowbell HP 400 Hz, pan ±20.
Synth lead and stabs
HP 100–200 Hz; presence 2–4 kHz; 1.5–2 s hall reverb (high amount, low size) at −14 dB; moderate stereo.
Rap vocal
EQ: HP 90 Hz, −3 dB at 300 Hz, +3 dB at 3–5 kHz; 1176 compression 6–8 dB (shouted vocals); de-esser; light saturation; 1/4 delay.
Gang vocals and chants
Doubles/triples panned ±40–100; HP 150 Hz; heavy compression; room or short plate; level almost equal to the lead vocal.
Buses, sidechain, master
Drum bus with 2 dB clipper; vocal bus with glue. Sidechain kick → 808. Master −8/−6 LUFS (2000s crunk was already loud), true peak −1 dBTP. For Dungeon Family / UGK −10/−9.
Common mistakes
808 covering the clap; chants too low (they're the hook!); leads without an HP that muddy the mix.
