How to Make Jazz Music
From ii-V-I progressions and swing feel to Dorian mode and tritone substitutions. A complete guide for producers and musicians building jazz from scratch.
Step 0: Detect the Key Before You Build
Jazz is the most harmonically complex genre. If you are sampling a jazz record or building alongside a reference track, detecting the key first prevents every mistake downstream: wrong chord voicings, wrong scale, wrong transpositions.
Step 01: BPM and Jazz Subgenre
Jazz spans the widest BPM range of any genre. The subgenre determines tempo, swing amount, and harmonic complexity.
| Subgenre | BPM | Feel | Common Keys | Key Artists | Pro Tip |
|---|---|---|---|---|---|
| Traditional/Swing | 120-200 | Loose, swinging | Bb, F, C, G | Louis Armstrong, Duke Ellington | Walking bass + ride cymbal define the swing era sound |
| Bebop/Hard Bop | 180-300 | Fast, complex | Bb, F, C, Eb | Charlie Parker, Miles Davis | Rapid ii-V-I substitutions, chromatic approach tones |
| Modal Jazz | 90-140 | Open, meditative | D Dorian, Phrygian | Miles Davis, John Coltrane | One or two chords sustained, explore modal colors |
| Jazz Fusion | 100-150 | Funky, electric | Minor, Dorian | Herbie Hancock, Weather Report | Electric piano, synth bass, pentatonic + Dorian solos |
| Neo-Soul/Jazz | 70-100 | Smooth, soulful | F min, C min | D’Angelo, Snarky Puppy | im7-IVm7 vamp with 9th/11th extensions |
| Lo-Fi Jazz | 70-90 | Relaxed, nostalgic | F min, D min | Lofi Girl style | Vinyl crackle, pitch wobble, simple 4-bar loops |
If you are new to jazz production, start with neo-soul jazz. The slower tempo (80-95 BPM), simple im7-IVm7 vamp, and partial swing (55-65%) are achievable with any DAW. Full bebop at 250 BPM requires live musicians or exceptional programming skills.
Step 02: The Swing Feel
Swing is the single most important element that separates jazz from every other genre. Get this wrong and the track will not sound like jazz, regardless of the chords.
Straight 8th notes divide a beat evenly (1 and 2 and 3 and 4 and). Swung 8th notes use a triplet subdivision where the first 8th note is longer and the second is shorter. At full swing (66%), the pattern sounds like a triplet: "1 - and - 2 - and." At 50% it sounds straight. At 70% it is very bouncy.
Jazz Drum Pattern by Style
| Style | Kick | Snare | Hi-Hat / Ride | Ghost Notes | Swing |
|---|---|---|---|---|---|
| Swing | Beat 1 + light 3 | Beats 2 + 4 | Ride cymbal, 1-2-3-4 | Light brushes or mallets | 60-70% |
| Bebop | Sparse, drop bombs | Comping, irregular | Ride melody, interactive | Constant hi-hat on 2+4 | 65-70% |
| Bossa Nova | Beat 1 only | Cross-stick 2+4 | Clave / 8th pattern | Soft brushes | 0% (straight) |
| Jazz Fusion | Four-on-floor or syncopated | Backbeat 2+4 | Closed, funky pattern | Ghost notes on snare | 30-50% (partial) |
| Neo-Soul/Modern | Beat 1 + syncopated | Half-time feel, 3 | Swung 8ths or 16ths | Dense ghost notes | 55-65% |
Real jazz swing cannot be fully replicated by DAW quantization. Authentic swing comes from the micro-timing of live musicians who breathe and interact. For the most natural result, use jazz drum samples that were recorded with live players (many free sample packs on Splice, Looperman, and Noiiz) rather than programming from scratch. Program your swing quantization to 60-66% as a starting point, then adjust by ear.
Step 03: Jazz Chord Progressions
Jazz harmony is built on 7th chords and extended chords, not triads. The ii-V-I is the foundation. Every other jazz progression is a variation, extension, or substitution of this movement.
The ii-V-I is to jazz what the I-IV-V is to blues. In C major: Dm7 - G7 - Cmaj7. The ii chord (iim7) creates tension, the V chord (V7) increases tension, and the I chord (Imaj7) resolves. Every jazz standard uses this movement hundreds of times, often in multiple keys within a single song.
Step 04: Jazz Scales and Modes
Jazz uses a different scale for each chord in a progression, not one scale for the whole song. This chord-scale theory is what makes jazz sound sophisticated and chromatic.
Over iim7: use Dorian mode. Over V7: use Mixolydian (or half-whole diminished for more tension). Over Imaj7: use major scale (Ionian). This is the basic ii-V-I chord-scale approach used by every jazz musician. Each scale change follows the chord and creates horizontal melodic motion that implies the harmony.
| Scale | Formula | Use Over | Sound | Guide |
|---|---|---|---|---|
| Major (Ionian) | 1 2 3 4 5 6 7 | Over Imaj7 chords | Bright, resolved | Major scale |
| Dorian Mode | 1 2 b3 4 5 6 b7 | Over iim7 chords | Minor but bright (major 6th) | Guitar Guide |
| Mixolydian Mode | 1 2 3 4 5 6 b7 | Over V7 dominant chords | Major with bluesy flat 7th | Guitar Guide |
| Melodic Minor | 1 2 b3 4 5 6 7 | Over altered dominant chords | Jazz minor, ascending feel | Guitar Guide |
| Diminished (Half-Whole) | H-W-H-W-H-W-H-W | Over V7 dominant chords | Chromatic, tense, bebop | Guitar Guide |
| Chromatic | 12 half steps | Approach notes, passing tones | Chromatic color | Guitar Guide |
The Dorian mode (1 2 b3 4 5 6 b7) is the most important scale for jazz producers and guitarists. It covers every iim7 chord in every ii-V-I progression. Unlike the natural minor scale, Dorian has a major 6th which creates a brighter minor sound. Miles Davis used D Dorian for "So What," the most listened to modal jazz composition ever recorded.
Dorian Scale Guitar GuideMixolydian (1 2 3 4 5 6 b7) is used over dominant V7 chords. In C major, G Mixolydian fits the G7 chord. The flat 7th in Mixolydian matches the b7 in the dominant 7th chord. Advanced players use the half-whole diminished scale (or "bebop scale") over the V7 for more chromatic tension before resolution to the I chord.
Mixolydian Scale Guitar GuideStep 05: Common Jazz Keys Reference
Jazz uses flat keys (Bb, F, Eb, Ab) more than any other genre because most traditional jazz instruments (trumpet, saxophone, clarinet) are Bb or Eb transposing instruments. Producers working without wind players can use any key.
| Key | Root Hz | 5th Note | 5th Hz | Camelot | Genre Context |
|---|---|---|---|---|---|
| C major | 261.63 Hz | G | 392 Hz | 8B | Jazz standards, beginner-friendly |
| F major | 174.61 Hz | C | 261.63 Hz | 7B | Wind instruments, Bb concerts |
| Bb major | 233.08 Hz | F | 174.61 Hz | 6B | Horn players (Bb instruments) |
| D minor | 146.83 Hz | A | 220 Hz | 7A | Modal jazz, neo-soul |
| F minor | 174.61 Hz | C | 261.63 Hz | 4A | Dark jazz ballads, lo-fi jazz |
| C minor | 261.63 Hz | G | 392 Hz | 5A | Fusion, neo-soul, hip-hop jazz |
Step 06: Jazz Arrangement Structures
Jazz arrangements follow different structures depending on whether you are producing a composed track or a more improvisational format.
Traditional Jazz Song Form (AABA)
| Section | Bars | Content |
|---|---|---|
| A section (1) | 8 bars | Main melody + chords |
| A section (2) | 8 bars | Repeat with variation |
| B section (bridge) | 8 bars | New key center or contrasting chords |
| A section (3) | 8 bars | Return to main melody |
Modern Jazz Production Structure
| Section | Bars | Elements |
|---|---|---|
| Intro | 4-8 bars | Piano or guitar vamp |
| Head (melody) | 16-32 bars | Full band, written melody |
| Solo section | 32+ bars | Improvised or written solo over changes |
| Outro/Head out | 8-16 bars | Return to head melody or fade |
For lo-fi jazz and neo-soul jazz production, you do not need to follow AABA form. A simple 4-bar or 8-bar chord loop (im7-IVm7 vamp or ii-V-I cycle) repeated with textural variation (vinyl crackle, Rhodes filter sweeps, percussion changes) is the standard modern approach. Most lo-fi jazz tracks on YouTube study music channels are exactly this: a 4-8 bar loop with texture.
Step 07: Mix and Master Jazz
Jazz mixing is more natural and transparent than hip-hop or EDM. The goal is space, warmth, and instrument separation - not maximum loudness.
Set every instrument to peak at -18 to -12 dBFS before processing. Jazz has high dynamic range - do not compress the life out of it. Leave headroom for natural peaks.
Piano: cut 200-400 Hz to reduce mud, boost 3-5 kHz for presence. Double bass: keep 60-120 Hz weight, cut above 2 kHz. Drums: minimal EQ, let the room sound breathe. Saxophone: boost 1-4 kHz for attack.
Use gentle compression. 2:1 or 3:1 ratio, slow attack (30-80ms) to preserve transients, medium release (150-300ms). Bus compression at 2:1 with high threshold (-15 to -20 dB) glues the mix without killing dynamics.
Use room or hall reverb (not plate). Small to medium rooms for bebop/hard bop (0.8-1.5s RT60). Larger halls for ballads (2-3s). Pre-delay 15-30ms to separate the dry sound before reverb tail. Send-based reverb, not insert.
| BPM | 8th | Dotted 8th | Quarter |
|---|---|---|---|
| 70 | 429ms | 643ms | 857ms |
| 80 | 375ms | 563ms | 750ms |
| 100 | 300ms | 450ms | 600ms |
| 120 | 250ms | 375ms | 500ms |
Jazz masters quiet. Target -16 to -14 LUFS for streaming (Spotify normalizes to -14 LUFS). True Peak: -1.0 dBTP. Preserve dynamic range - jazz should breathe. Avoid over-limiting. A jazz master sounds quieter than a pop master at the same playback volume.

Jazz Production FAQ
What BPM is jazz music?
Jazz BPM varies widely. Slow ballads run 40-70 BPM. Medium swing jazz is 70-160 BPM. Bebop pushes 180-300 BPM. For producers starting out, neo-soul jazz at 80-95 BPM is the most accessible entry point.
What chords are used in jazz?
Jazz uses 7th chords as the minimum: maj7, m7, dom7, and m7b5 (half-diminished). The ii-V-I (iim7 - V7 - Imaj7) is the foundational progression. Extended chords (9ths, 11ths, 13ths) and tritone substitutions are common in bebop and modern jazz.
What scales are used in jazz?
Jazz uses chord-scale theory: Dorian over iim7 chords, Mixolydian over V7 dominant chords, and major scale (Ionian) over Imaj7. Melodic minor, harmonic minor, and the diminished scale are used for more advanced chord substitutions. The Dorian mode is the most important jazz scale to learn first.
What is swing feel and how do I add it in a DAW?
Swing feel means 8th notes use a triplet subdivision (long-short) instead of equal duration. Set your DAW's swing/groove quantization to 60-66% for standard jazz swing. Better results come from using pre-swung jazz drum loops recorded by live musicians. Real jazz swing is subtle timing that resists perfect quantization.
