Choirs and Gang Vocals

Role in the Mix

This guide covers ensemble vocals: gospel and church choirs, classical choirs (SATB), pop choirs and "stadium chants," gang vocals (punk, hardcore, pop-punk, metalcore: a group shouting in unison "hey!", "oh-oh"), stadium choirs in EDM and pop ("oh-oh-oh" in the style of Coldplay/Avicii), children's choirs, vocal pads. Unlike backing vocals, here the goal is a sense of mass: many people, one sound, size and space. The mix works on width, density, and perspective, while handling the lack of definition (many voices = scattered consonants and "averaged" pitch).

Recording and Preparation

• Gang vocals with few people: record many passes (4–8), moving the people around a mic (changing distance and angle) and changing positions in the room; even a single singer can create a believable gang with many passes in different voices (register, intention, distance): Production Expert describes this technique with a single singer and a single mic.
• Real choir: stereo pair (ORTF, AB) in front of the choir + spot mics per section + ambience mics; Sound On Sound recommends, where possible, a single mic for several singers, balancing them by distance, and stereo setups for ensembles and choirs.
• Remote choirs (singers recorded separately): Mike Senior has documented remote vocal ensemble productions: they require a lot of alignment and tuning work and a common space created in the mix.
• Libraries: Spitfire Eric Whitacre Choir, EastWest Hollywood Choirs, Arturia Augmented Voices, Strezov; programming by syllable (word builder) and CC dynamics.

Editing

• Align the attacks of the key words (especially in gangs: "hey!" has to be a single hit) with VocAlign or by hand; leave a little looseness in the rest for realism.
• Consonants: keep the "s" and "t" on one or two takes, cut them on the others.

Gain Staging

Peaks per take −16/−12 dBFS; the choir bus can be very dense (low crest factor).

Corrective EQ

• HP 120–200 Hz for gangs and pop choirs (100 Hz for classical choirs with basses).
• Mud 200–500 Hz (the sum of many voices): −3/−5 dB on the bus.
• Harshness 2–4 kHz from the shouts: dynamic EQ.
• Sibilance multiplied: firm de-esser.

Creative EQ

• Gang: +2/+3 dB at 1–2 kHz for "the shout" and LP at 8–10 kHz (they are behind, they must not be as bright as the lead).
• Stadium/EDM choirs: air at 10–12 kHz, moderate presence.
• Gospel choirs: more present warmth at 200–300 Hz, presence at 2–3 kHz.

Compression

• Bus: VCA or opto 3:1–4:1, 4–8 dB for a single block.
• Gang: aggressive compression (FET, 6–10 dB) + saturation.
• Classical choir: none, or 1–2 dB.

Saturation

Light saturation/distortion on gangs for energy (punk, hardcore); tape on choirs for cohesion.

Delay

Rare; short slap for thickness; throw on the last syllable of a chant.

Reverb (Central)

• Gang: large room (1–1.5 s) or short hall for "the room full of people"; plate for pop-punk.
• Stadium choirs: large hall 2.5–4 s, with pre-delay 20–40 ms.
• Classical/gospel choirs: church or hall (2–4 s); consistent with the rest of the arrangement.
• HP 250–300 Hz on the return.

Modulation and Pitch

• Doubler/chorus to multiply a few takes (Waves Doubler, MicroShift, Pitcher with different detune and delays), but one real take is worth more than three artificial doubles.
• Octave below in parallel (Pitcher/Pitch Shifter) for more "manly" choirs in chants.

Stereo and Panning

• Gang: takes distributed across the whole stereo field (−100/+100), with the more "central" ones louder; the lead stays in the center and defined.
• Choirs: SATB layout (sopranos left, altos center-left, tenors center-right, basses right, or other conventions), or a wide stereo pair.
• Wideners on the bus (Spreader) with correlation control.

Sidechain

Ducking the choir from the lead (1–3 dB) or dynamic EQ 2–4 kHz.

Automation

• Choirs and gangs come in on the final choruses and in bridges: volume and reverb automation.
• Crescendo of classical choirs with CC/fader.

Differences by Genre

Common Mistakes

• Copying the same take several times: it doesn't become a choir.
• Unaligned attacks in the gangs: limp "heys."
• Uncontrolled low-mid of the sum: mud.
• Choir brighter and louder than the lead.
