Reverb Automation Tip
Another favourite low-effort trick for trance breakdowns:
shrinking the reverb space across the build to add tension that nobody can quite put their finger on.
The method being start reverb big. hall with 3-5s decay or thereabouts, diffusion set low so its smeary and atmospheric. then automate it toward a tight plate, maybe 1-1.5s, high diffusion across the full 16 or 32 bar build.
listener doesnt consciously hear 'oh the rooms getting smaller' but their brain feels it by the time the drop hits. proper subtle tension. basically tricking the ear into needing release.
if your in ableton, two reverb instances on a return crossfaded with one macro works well. or send to both returns and automate the levels in opposing directions. valhalla supermassive is lovely on the hall side if you got it but the stock reverb does the job tbh.
automation 16 bars minimum, longer the better. if you can hear the change happening then you've gone too fast.
Works especially well paired with a slow high pass sweep on the pads or vocal - same principle, shrinking the high end while you shrink the space. combine this with other tension techniques, for load up the layers of tension in your builds.
