The center
In almost all modern genres the center holds: kick, 808/bass, snare, lead vocal. These are the elements with the most energy and must be solid even in mono.
The sides
- Doubled guitars and synths: wide L/R (even at 100%: LCR panning).
- Backing vocals, doubles and ad-libs: distributed, often fanned out.
- Pads and reverbs: wide.
- Hi-hats and percussion: slightly off-center to create the “drums as seen by the audience” or by the drummer (choose and stay consistent).
Width tools
- Panning and real doubles: the most natural way.
- Haas effect: the same sound delayed by 10–30 ms on one side; watch out for mono compatibility (cancellations).
- Chorus and micro-pitch (±5–10 cents between L and R).
- Mid/side: separate EQ on center and sides; cut the bass of the sides below 120–150 Hz.
- Stereo wideners: with moderation.
Depth
The mix also has a front–back axis: more volume, more highs and less reverb = close; fewer highs, more reverb and shorter pre-delay = far.
Checks
- Phase correlation meter always above 0 on the important parts.
- Frequent mono listening: clubs, phones and small speakers are often mono.
Example in A minor
808 and kick in the center in mono; Am – F pad with wide chorus; two doubled guitars or synths L/R; vocal in the center, doubles ±30%, ad-libs ±60%, long reverb filtered on the sides.
Real-world example
Many stereo versions of Beatles records from the 1960s put whole instruments on one side and the vocals on the other: a good comparative listen to understand how much modern panning has become more centered in the low end of the mix.
