Festival trap

History and character

“Festival trap” is the label used for EDM trap made for festival main stages, developed from 2013 onward as trap entered big events: in 2013 Ultra Music Festival hosted five trap producers (including DJ Craze, Baauer and Flosstradamus) and Tomorrowland opened a “trap stage”. The sound crosses EDM trap with the logic of big room house: long builds, drops designed for “shock”, chants and vocal samples for the crowd to shout, synth brass and horns, and sometimes hardstyle- or big room-style kicks in the builds.

Associated artists: Carnage (“Bricks” with Migos, 2014; “Incredible” with Borgore, 2015; collaborations with KSHMR, Timmy Trumpet, Headhunterz), Yellow Claw (a Dutch duo from Amsterdam, active since 2010, mixing trap, hip hop, dubstep, hardstyle and moombahton; “Shotgun” feat. Rochelle, 2013; label Barong Family founded in 2014), DJ Snake (“Turn Down for What” with Lil Jon, 2013), Flosstradamus, Diplo/Major Lazer, GTA, Bro Safari, NGHTMRE, Slander in their early work, Valentino Khan, Henry Fong, Party Favor. The term has no precise birth date and is used mostly by DJs, fans and digital stores; the boundary with EDM trap and hybrid trap is blurry.

The aesthetic is that of the American and European festival of the mid-2010s: “turn up”, stadium energy, humor and aggression, lots of compression, short drops (16 bars) alternating with builds. From the second half of the 2010s the sound merges with dubstep and future bass (hybrid trap) and with melodic “heaven trap”.

Scales and keys

Dark and epic, with “exotic” colors used as hooks. Examples in F minor and E. Roman numerals relative to the natural minor.

Natural minor (Aeolian)

• Formula: 1 2 b3 4 5 b6 b7. On F: F G Ab Bb C Db Eb.
• Chords: i Fm, ii° G°, III Ab, iv Bbm, v Cm, VI Db, VII Eb.
• Use: brass and supersaw leads over i–VI–VII; 808 on the tonic.

Harmonic minor

• Formula: 1 2 b3 4 5 b6 7. On F: F G Ab Bb C Db E. Characteristic note: the leading tone E.
• Chords: i Fm, ii° G°, III+ Ab+, iv Bbm, V C, VI Db, vii° E°.
• Use: “Eastern” leads and trumpets; major V at the end of the build.

Phrygian dominant

• Formula: 1 b2 3 4 5 b6 b7. On E: E F G# A B C D.
• Chords: I E, bII F, iii° G#°, iv Am, v° B°, bVI+ C+, bvii Dm.
• Use: “exotic” hooks (flutes, zurna, trumpets) widely used in festival trap and moombahton.

Minor pentatonic

• Formula: 1 b3 4 5 b7. On F: F Ab Bb C Eb.
• Use: chants, brass riffs, 808.

How to choose

• Stadium drop: Aeolian or pentatonic with brass.
• Exotic hook: harmonic minor or Phrygian dominant (in moderation).
• Build: major V (from harmonic minor).

Common mistakes and an example

• Exotic hooks work if they stay short (a 1–2 bar phrase repeated); harmonizing them with full chords makes them sound “cartoonish”.
• Listening example for the language: the synth trumpet leads and drop chants of Carnage and Yellow Claw.
• Formula to remember: harmonic minor on A = A B C D E F G#; the augmented second F–G# is the “exotic sound”; E Phrygian dominant (E F G# A B C D) is the same material seen from the fifth degree.

Harmony

• Minimal: melodic brass or lead riffs without full chords; 808 as bass and tonal definition.
• Build: progressions of 2–4 chords (VI–VII–V) with supersaws and choirs.
• Pedal in the drop; V–i cadences only before the drop.
• Voicings: power chords and octaves in the brass.

Typical progressions

Rhythm and groove

• Trap half-time at 140–150 with big room-style builds: accelerating snare, sometimes a four-on-the-floor kick in the build that then “falls” into the half-time of the drop.
• Trap hats in eighth notes with rolls, syncopated 808s, snare + clap on beat 3.
• Short (16-bar), very rhythmic drops.

Drums

Convention: 16 sixteenth notes; quarter notes on 1, 5, 9, 13.

Kick and 808

• Drop: kick on sixteenths 1, 8, 11 (as in r-trap) with 808; build: four-on-the-floor kick on 1, 5, 9, 13 (as in r-bigroom) accelerating into eighth and sixteenth notes.

Snare and clap

• Sixteenth 9 in the drop (beat 3); very loud clap + snare; in the build, snare roll 1/4 → 1/32.

Hi-hats and percussion

• Trap hats in eighth notes with rolls; tribal toms in the builds; air horns, gunshots, “hey” samples.

Dynamics and groove

• High, uniform velocities; swing 0.

Interaction with the bass

• Long 808s that follow the kick; brass answering in the gaps.

How it changes by section

• Intro with chant; big room build (four-on-the-floor kick, snare roll, riser, “put your hands up”); trap drop; short breakdown.

Fills and transitions

• Silence with a vocal sample (“drop!”), reverses, toms.

Choosing sounds

• Distorted 808s, fat claps, big room kicks for the builds.

Typical mistakes

• Builds that are too long; untuned 808; drops with no space.

The hybrid “build” in detail (8 bars at 150 BPM)

• Bars 1–4: four-on-the-floor kick (1, 5, 9, 13), clap on 5 and 13, snare roll in quarter notes moving to eighth notes in bar 3.
• Bars 5–6: sixteenth-note snare roll, eighth-note kick, high-pass on the drums rising from 50 to 300 Hz, riser with pitch +12.
• Bar 7: 1/32 snare roll, “hands up” chant, reversed crash.
• Bar 8: silence or just the “drop” vocal sample; on beat 1 of the next bar, impact + 808 + half-time snare on 9.
• Variation: the drop starts with a 1-bar “fake drop” (just 808 and vocal) and then the full drums come in.

Bass

• 808: long, distorted, tuned, with glide; in hybrid drops a growl or reese on top.
• Notes: tonic, b7, 5; octave slides.
• Sidechain from the kick.
• Range: 808 E1–A1.
• Building the 808: a long 808 sample (decay 1–2 s) or a sine with a pitch envelope (+12 → 0 semitones in 40–60 ms); soft saturation (Fruity Soft Clipper, Decapitator, Trash 2) to generate harmonics at 100–300 Hz; mono glide (portamento 80–120 ms) for the octave slides; cut below 25 Hz.
• Tuning: check the 808's note with an analyzer (Wave Candy or a tuner); the kick should be tuned to the same note or to the fifth.
• Mistakes: an 808 that “plays” a different note because the pitch envelope is too long; glide in polyphony; distortion that changes the perceived volume from note to note.

Harmonic instruments

• Synth brass and horns (stabs and riffs), supersaws in the builds, epic choirs, strings in the breakdowns.

Melody and vocals

• Chants and vocal samples for the crowd to sing, guest rappers (Migos, Lil Jon), brass or exotic lead hooks.
• Effects: short delay and reverb in the drop, long reverb in the builds.

Instruments

• TR-808 and trap kits, big room kick for the builds, synth brass, supersaws, choirs, strings, vocal samples, air horns and FX.

Drum patterns

Synths and sounds

• Jup-8 V — Trap brass: Unison saws with a filter envelope (attack 10–20 ms): powerful horns.
• CS-80 V — Wide brass: Epic brass for the builds.
• OP-Xa V — Build supersaw: Wide chords with risers.
• Mini V — Synth 808: Sine with pitch envelope and glide.
• Augmented Voices — Choirs: Epic choirs in the builds.

Song structure

• Length 3:00–3:30; tracks built to be mixed quickly in festival sets.

Mixing and mastering

Sonic goal

• Maximum energy: huge 808, in-your-face clap, wide brass, very high loudness.
• References: Carnage, Yellow Claw, DJ Snake.

Kick

• EQ: high-pass 30 Hz, +2 dB at 60 Hz, −3 dB at 300 Hz, +3 dB at 4 kHz; clipper; mono.

Snare and clap

• EQ: high-pass 150 Hz, +2 dB at 200 Hz, +3 dB at 3 kHz; compression + clipper; short reverb.

Hi-hats and percussion

• High-pass 500 Hz; toms with reverb in the builds.

808

• Saturation/clipper for harmonics, mono, limiter; +2 dB at 100–150 Hz.

Brass, supersaws, choirs

• High-pass 200 Hz, width 140%, sidechain.

Vocals and samples

• Heavy compression, distortion, short delay.

FX

• Air horns and gunshots with a high-pass, controlled level.

Buses and groups

• Drum bus with a clipper; 808 bus; Music bus with sidechain.

Sidechain

• Kick/808 → brass and pads.

Master

• Chain: EQ → glue → clipper → limiter.
• Indicative targets: −5/−3 LUFS integrated for the festival; −7 for streaming; true peak −0.3/−1 dBTP.

Common mistakes

• 808 that disappears on small speakers; brass that mask the clap; too many FX.

Reference tracks for the mix

• Carnage feat. Migos — Bricks (2014); Yellow Claw feat. Rochelle — Shotgun (2013); DJ Snake & Lil Jon — Turn Down for What (2013).

Managing energy between build and drop

• The build has lots of highs (risers, rolls) and little sub; the drop has sub and mids: the spectral contrast makes the drop feel louder even at the same LUFS. Automate a high-pass on the music bus in the build (up to 200–300 Hz) and remove it suddenly at the impact.
• Leave 1–2 dB of headroom in the build compared to the drop on the short-term meter.

Lead vocal (guest rapper)

• EQ: high-pass 100 Hz, −3 dB at 250–350 Hz, +3 dB at 3 kHz; serial compression (FET 6 dB + opto 2 dB); de-esser; saturation; 1/8 delay and short reverb to stay “in your face”; ad-libs panned ±40% with distortion.
