The lead singer (Lead) is the movie star, while the backing vocals (Backing Vocals) are the lighting and the backdrop. If the backdrop is too flashy, the main performer will be overshadowed. If the backdrop is too dark, the scene becomes dull.
In Live Sound, the biggest mistake is mixing the backing vocals… to sound exactly like the lead (Loud, Clear, Bright). At nguyenthiet.com, we will show you how to turn disparate voices into a smooth “velvet carpet” that supports the song.| Contents: |
1. Rule #1: Grouping (Bus Processing)
Don’t process each backing vocal mic individually. Send them all to a Stereo Group (for example: BGV BUS).- Benefit: You only need one fader to raise or lower the entire backing vocal section.
- The Glue: Insert a compressor on this Group. Compress more aggressively than the Lead Vocal (Ratio 4:1, GR 3-5dB). This makes the voices “stick” together into a single cohesive block so no one sticks out or falls back.
2. Panning: Avoid the center
The Center position is the throne of the Kick, Snare, Bass and the Lead Vocal. Don’t let backing vocals crowd it. Strategy:- If there are 2 backing vocals: Pan hard left (100% Left) and hard right (100% Right).
- If there are 3: one in the center (but at low volume), two on the sides.
- If there are 4: Pan L50, R50, L100, R100.
3. EQ: “Bandpass” strategy
Backing vocals don’t need the same full frequency content as the lead. We want them to “blend”, not “stand out”. EQ settings for the Backing Vocal Group:
- Low Cut (HPF): Set higher than the Lead. Around 150Hz – 200Hz. Backing vocals don’t need the low end.
- High Cut (LPF): This is the secret. Roll off the extreme highs (above 8kHz – 10kHz). Reducing the “brightness” (Air) will make the backing vocals sound more distant (Depth), leaving the sparkle to the lead singer.
- Cut the mids: Slightly reduce the 2.5kHz – 3kHz region (where the lead needs presence) to avoid masking.
4. Reverb: Push back into the background
In a 3D space, the more Reverb (Wet) a source has, the further away it will appear.- Lead Vocal: Moderate reverb with longer pre-delay (so the vocal still feels close).
- Backing Vocal: More reverb, short pre-delay (0ms). Use a darker Hall or Plate to blur the backing vocals into a smooth background pad.
Frequently Asked Questions
- 1. How do I deal with sibilance across the backing vocals?
- When multiple singers pronounce “S” at the same time it can sound like a snake hiss. Use a De-esser on the backing vocal Group. Be more aggressive than you are on the Lead Vocal.
- 2. Should I use a Chorus effect on the backing vocals?
- Absolutely! Chorus or a Doubler thickens the backing vocals, widens them and makes them sound smoother, helping to mask small tuning issues.
