History and character
K-hip hop is South Korean hip hop. It was already present in early K-pop (Seo Taiji and Boys, 1992–1996, with songs such as Come Back Home) and grew into an independent scene in the late '90s and 2000s with Drunken Tiger (Tiger JK), Epik High (Tablo, Mithra Jin, DJ Tukutz: Fly, Love Love Love, 2005), Dynamic Duo, Garion, Verbal Jint and Leessang. In the 2010s strong independent labels emerged, such as AOMG (founded by Jay Park), Illionaire Records (Dok2, The Quiett), Hi-Lite Records and H1GHR MUSIC, along with artists like Zico (formerly of Block B; Any Song, 2020, which became a viral phenomenon), BewhY, Changmo, pH-1, Sik-K, Simon Dominic, Beenzino and Lee Young-ji. The talent show Show Me the Money (Mnet, since 2012) and its female spin-off Unpretty Rapstar brought Korean rap into the mainstream.
Hip hop is also a pillar of K-pop idol music: groups have “main rapper” and “rapper” roles, and many idols have independent rap careers (G-Dragon, RM, SUGA/Agust D, Bang Chan, Changbin and Han of Stray Kids as 3RACHA, Mino, Bobby, Soyeon). YG and HYBE were born with a strong hip hop identity (BIGBANG, and BTS in their early days with 2 Cool 4 Skool, 2013).
The sound ranges from jazzy boom bap (jazz and soul samples, Epik High, Beenzino) to trap and melodic rap (Sik-K, pH-1), to drill and rage in the most recent productions, with many pop and R&B crossovers. The Korean language, with its closed syllables and double consonants, allows very fast flows and distinctive internal rhymes; English is used for hooks and punchlines.

How to choose
Jazzy boom bap: Dorian with sevenths. Trap: Aeolian or Phrygian. Drill: harmonic minor. Melodic rap/crossover: Aeolian with the relative major in the chorus.
Harmony
Function
Cyclical, minimal harmony: a loop of 1–4 chords (often a 2–4 bar sample) that repeats throughout the song. Variety comes from the arrangement, the flow and the dropping of parts. In idol crossovers the chorus may have a full pop progression.
Techniques
- Looped sample (jazz, soul, Korean OSTs, traditional music) chopped and re-pitched.
- Chords with sevenths and ninths in boom bap (Rhodes, jazz piano).
- 808 pedal with melodies that change on top in trap.
- Loop change in the chorus or the bridge.
Harmonic rhythm
1 chord every 1–2 bars; many songs have a single chord or an atonal riff.
Typical progressions
| Name | Key | Chords | Degrees | How to use it |
|---|---|---|---|---|
| Jazzy boom bap loop | D Dorian | Dm9 G13 | i9 IV13 | Two chords with extensions: the sound of jazz and soul samples (Epik High, Beenzino). |
| Minor trap loop | G minor | Gm Eb | i VI | The simplest loop: it leaves room for the flow and the 808. |
| Melancholic | A minor | Am7 Fmaj7 C G | i7 VImaj7 III VII | Melodic rap and crossover choruses. |
| Dark Phrygian | E Phrygian | Em F Em F | i II i II | Ghostly bells and piano, 808 on the b2. |
| Harmonic drill | C minor | Cm Ab G Cm | i VI V i | The leading tone B in the major V: drill tension. |
| Soul sample | Eb major | Abmaj7 Gm7 Fm7 Bb7 | IVmaj7 iii7 ii7 V7 | '70s soul loop for “chill” and nostalgic tracks. |
| Pop crossover | D major | Bm G D A | vi IV I V | Pop sung chorus inside a rap song (Zico's Any Song style is close to this light approach). |
Rhythm and groove
Boom bap (80–100): swing 54–62% on the hats and ghost notes, kick and snare “behind the beat” in J Dilla style in the jazzier tracks. Trap (130–150 felt in half-time): triplet hats and rolls, syncopated 808s, snare on 3. Drill (140 felt at 70): snare shifted to 3 and the last sixteenth note, syncopated hats, sliding 808s. In idol songs the beat often changes between verses and chorus.
Drums
Kick
Boom bap: steps 1, 8, 11 (syncopated kick) with varied velocity. Trap: 808 + kick on 1, 7, 11. Drill: sparse, syncopated kicks.
Snare and clap
Boom bap: on 2 and 4 (steps 5, 13), snare sampled from records, ghost notes. Trap: on 3 (step 9) with clap. Drill: steps 9 and 12/16 (“bouncing” snare).
Hi-hat and percussion
Boom bap: swung eighth-note hats, occasional open hat; trap: sixteenth-note hats with triplet and thirty-second-note rolls; drill: hats in syncopated triplet patterns. Percussion: shaker, vinyl samples, Korean percussion (janggu, buk) in some songs.
Interaction with bass and vocals
The rap flow locks in with the drums: the drums are simpler when the flow is complex. The 808 follows the kick.
By section
Verse: full or filtered beat; hook: full beat with layers; bridge: beat removed or changed; outro: fading loop.
Fills
Few: dropping the whole beat for one bar (room for the punchline), stutters, scratches in boom bap, risers in trap.
Sounds and mistakes
Vinyl samples (SP-1200, MPC) in boom bap, 808s and modern samples in trap. Mistakes: quantizing everything in boom bap (it loses the groove); trap hats with no variation.
Bass
- Sound: sampled or electric bass (boom bap), long, saturated 808s (trap and drill), sine sub.
- Notes: root, octave, b2 and fifth; 808 slides in trap and drill.
- Relationship with the kick: boom bap: bass follows the kick; trap: short kick on top of the 808's attack.
- Examples: Epik High — Fly (pop boom bap), Zico — Any Song (light funky bass), Stray Kids/3RACHA (heavy 808s).
Harmonic instruments
Samples of piano, Rhodes, strings, winds and voices (boom bap), bells, piano and dark pads (trap), “Eastern-sounding” strings and flutes (drill), sampled guitars, traditional Korean instruments (gayageum, daegeum, haegeum) in fusion tracks. Voicings with sevenths and ninths in boom bap, fifths and octaves in trap.
Melody and vocals
- Rap: fast, tight flows exploiting Korean syllables, internal and multisyllabic rhymes, switching between Korean and English, flow changes mid-verse; in the more rap-oriented groups, rappers with different timbres (deep, nasal, technical).
- Hook: sung or rapped-sung, often with Auto-Tune; R&B choruses entrusted to a guest singer.
- Ad-libs: short, panned, with effects.
- Effects: Auto-Tune in melodic rap, eighth-note delay on the last words, doubles (dubs) on key words, telephone filter in intros.
Instruments
Rap vocals, singer for the hooks, sampler and drum machine (MPC, SP-1200, 808), 808 and bass, piano/Rhodes, jazz and soul samples, synths, strings, traditional Korean instruments, turntables (scratching).
Drum patterns
Synths and sounds

Song structure
| Section | Bars | Notes |
|---|---|---|
| Intro | 4–8 | Sample or filtered loop, sometimes a spoken phrase |
| Verse 1 | 16 | Rap |
| Hook | 8 | Sung or rapped |
| Verse 2 | 16 | Another rapper or a different flow |
| Hook | 8 | |
| Bridge / verse 3 | 8–16 | Beat changed or removed |
| Final hook | 8 | |
| Outro | 4–8 | Fading loop |
In idol songs the form follows K-pop (pre-chorus, dance break). Length 2:30–3:45.
Mixing and mastering
Sonic goal
Clear rap vocal up front, powerful drums and bass, samples with character. Boom bap: warm and dirty; trap: huge sub and bright highs. References: Epik High — Fly, Zico — Any Song, BewhY — Forever, Stray Kids — God's Menu (idol rap), Jay Park — All I Wanna Do.
Kick
Boom bap: HP 30 Hz, +2 dB at 60–80 Hz, saturation, 4:1 compression at 3 dB. Trap: short kick with click at 3–5 kHz, clipper. Center.
Snare
Boom bap: body 200 Hz, crack 3–5 kHz, parallel compression, short room. Trap/drill: layered clap, HP 150 Hz, 0.6 s plate.
Hi-hat and percussion
HP 400 Hz; boom bap with a light LP (vinyl); trap with hats 15–25% to the sides.
Bass / 808
HP 25 Hz; sub 40–60 Hz; saturation on the mid layer; clipper; mono below 150 Hz.
Samples and instruments
HP 120–200 Hz; tape/vinyl saturation; LP at 10–12 kHz in boom bap; dynamic dip at 2–4 kHz from the vocal.
Rap vocal
- EQ: HP 100 Hz; −2 dB at 250–400 Hz; presence +3/+4 dB at 3–5 kHz; air +2 dB.
- Compression: heavy, 1176 (8:1, 6–8 dB) + LA-2A (3–4 dB).
- De-esser: 5–7 kHz.
- Saturation: for the attack of the consonants.
- Space: dry or a short slapback (80–120 ms), eighth-note delay on the last words.
- Dubs: doubles on key words hard L/R at −6 dB.
Sung hook
Pop chain (tuning, serial compression, plate + delay); wider and more reverberant than the rap vocal.
FX
Scratches, stutters, vinyl crackle, risers.
Buses and groups
Drum bus with 2–4 dB compression and saturation; vocal bus 1–2 dB.
Sidechain
Kick → 808 (trap, 3–5 dB); vocal → beat (dynamic 1–2 dB at 2–4 kHz).
Master
Chain: EQ → compressor 1–2 dB → clipper → limiter. Boom bap −10/−8 LUFS; trap/drill −7/−5 LUFS. True peak ≤ −1 dBTP. PLR 7–10 dB.
Common mistakes
Rap vocal not compressed enough (fast Korean syllables get lost); 808 and kick in conflict; samples with too many mids that cover the vocal.
