Role in the mix
Brass (trumpet, flugelhorn, trombone, French horn, tuba) and the pop/funk horn section (typically trumpet + tenor sax + trombone, often with alto or baritone sax) bring punch, accents and energy: stabs and "hits" in funk, soul, ska, salsa and Latin pop; melodic lines and countermelodies in jazz and big band; epic pads and fanfares in soundtracks; riffs in modern pop (Bruno Mars, Mark Ronson). Approximate ranges (sounding pitch): Bb trumpet from E3 (≈165 Hz) to C6 and beyond; tenor trombone from E2 (≈82 Hz); horn from B1 to F5; tuba down to about D1. The sound radiates from the bell: it is very directional and has enormous dynamics (pp–fff), with the strongest harmonics between 1 and 5 kHz: loud horns easily become shrill.
Recording and choosing the sound
- Mic 30–100 cm from the bell, slightly off-axis (horns on-axis are harsh); ribbons (Royer R-121, Coles 4038) are a classic on trumpet; condensers for trombone and horn (the horn is often miked from behind, where the bell points, or with the room).
- Section: one mic per instrument + an overall pair; or the section gathered around a single mic. Sound On Sound has specific articles on recording and arranging horn sections.
- Libraries: Native Instruments Session Horns, CineBrass, Spitfire, Chris Hein Horns, Sample Modeling (physical modeling, expressive), Arturia Augmented Brass. Program CC1/CC11, articulations (stabs, falls, doits, shakes, sforzando) and realistic lengths; the breath between phrases.
- Section doubles: in pop the section is recorded 2–4 times (panned) for a bigger sound.
Gain staging
Peaks −14/−10 dBFS; crescendos and sforzandos have peaks of +10/+15 dB: handle them with automation and compression.
Corrective EQ
- HP: trumpet 120–200 Hz, sax 80–120 Hz, trombone 60–80 Hz, tuba 30 Hz.
- Mud 200–400 Hz of the section: −2/−3 dB.
- Honk/nasality 800 Hz–1.5 kHz (sax): −1/−3 dB.
- Shrillness 2–5 kHz of the trumpet at forte: dynamic EQ or a wide de-esser, −2/−4 dB on the peaks.
- Key noise (sax) 2–6 kHz: editing or dynamic EQ.
Creative EQ
- Pop section brightness +2 dB at 6–8 kHz (with a smooth EQ).
- Body +1/+2 dB at 200–300 Hz for trombones and baritone in funk.
- Presence +1/+2 dB at 1.5–3 kHz in dense mixes.
Compression
- FET (1176) on the funk section: medium attack, fast release, ratio 4:1, 4–6 dB: even, aggressive stabs.
- Opto (LA-2A) for jazz lines and solos (2–4 dB).
- VCA on the horn bus (2:1–4:1, attack 10–30 ms) to glue.
- Parallel for "explosive" stabs.
- In orchestral work: none; automation and CC.
Transient shaper
Attack + on stabs in dense mixes (funk, salsa); Attack − on libraries that are too "hard".
Saturation
Tape or tube (Studer, Decapitator in A mode, Distructor) to blend the section; more obvious saturation for a vintage sound (Daptone, Amy Winehouse) or a dirty one (ska punk).
Delay
- Pop/funk: short delays or light slaps for thickness; throws on the final stabs.
- Jazz/orchestra: none.
Reverb
- Plate 1.2–2 s (funk, soul, pop): the classic sound of '60s–'70s horn sections.
- Hall 2–3 s (orchestra, big band in a hall), with brass placed at the back (fewer highs and more ambience).
- Pre-delay 15–30 ms, HP 200 Hz on the return.
Modulation
Rare: light chorus on section doubles in pop; harmonizer as an effect.
Stereo and panning
- Funk/pop section (audience perspective): trumpet −30/−40, tenor sax 0/+10, trombone +30/+40; baritone near the trombone; section doubles at ±60–80.
- Big band: saxes front and center, trombones behind, trumpets at the back; each section spread from left to right.
- Orchestra (American seating): horns left/center-left behind the woodwinds, trumpets center-right, trombones and tuba on the right.
- Never everything in the center: horns clash with the vocal.
Sidechain
- Dynamic EQ at 1–4 kHz from the vocal under the countermelodies.
- Horns are rarely a sidechain source.
Automation (essential)
- Volume: the horns come up on the stabs between phrases and go down under the vocal.
- Crescendos and diminuendos (CC11) in libraries.
- Reverb send on the final chords.
Differences by genre
| Genre | Approach |
|---|---|
| Funk / soul | tight section, FET, plate, L/C/R pan |
| Ska / reggae | stabs on the offbeat, slap, bright |
| Salsa / Latin | powerful trumpets and trombones, 2–3 kHz presence, room |
| Jazz / big band | natural, light opto, hall |
| Modern pop | section doubles, brightness, compression |
| Soundtrack | hall, perspective, CC, no compression |
Common mistakes
- Shrill trumpets at 2–5 kHz at forte.
- Mono section in the center that covers the vocal.
- Libraries with static CC: robotic horns.
- Orchestral brass too close and bright (they lose depth).
