The fourth beat of bar two is missing entirely, and that hole is the most important thing in the grid. Everything is soft: the kick tops out at 94, the rimshot sits at 48, and the maracas run every offbeat sixteenth in the low thirties so they read as air moving rather than as a part. Two closed hats a bar. One open hat in the whole loop, on the and of 2 of bar two, filling the bar that is about to lose its downbeat. Play it at low volume with a long reverb and the missing kick will sound intentional rather than absent.

What it is

What happened when techno producers made records for the chillout room and then discovered they preferred them. The Orb, Aphex Twin's Selected Ambient Works, B12, Global Communication and the Warp Artificial Intelligence series are the reference documents, mostly 1990 to 1994. The rhythm is present but demoted: it is there to give the listener something to hold onto while a pad takes ninety seconds to open. This is the one place in the techno family where dropping a beat is normal rather than a mistake, and where the drums are allowed to be quieter than the reverb they are sitting in.

What it sounds like

Soft kicks with the click filtered off, pads that arrive from somewhere behind the speakers, and a maraca or shaker figure so quiet it registers as texture. Melodies are simple and modal, played on detuned digital synths with a lot of chorus. Field recordings, tape noise and long delay tails fill the space between events. Nothing is compressed hard, so the loud parts are actually loud and the quiet parts genuinely disappear.

Key elements

  • A kick that gives wayFour to the floor most of the time, but the arrangement drops beats and whole bars. The pulse is a reference point rather than a rule.
  • Pads with long attacksTwo to four seconds to reach full volume, so a chord change happens across a bar rather than on a beat. The filter opens over sixteen bars on top of that.
  • Reverb as an instrumentReverbs of eight seconds and more, mixed as loud as the source. Most of what you hear on these records is a tail rather than a note.
  • Quiet percussionMaracas or a shaker running sixteenths at velocities in the thirties. It gives the ear a grid without ever becoming the groove.
  • Field recordingsRain, birds, radio, a room. Placed low in the mix and looped at a length that does not divide into the bar, so it never repeats predictably.

How to get them

  • KickTake a 909 kick and low-pass it at around 200Hz, then add a slow fade-in of about 10ms so there is no click at all. It should feel like a heartbeat, not a hit.
  • PadsThree detuned saws, attack at 2 seconds, release at 4, a chorus and a wide stereo spread. Automate the cutoff from 400Hz up to 6kHz across sixteen bars.
  • ReverbA hall at eight seconds with pre-delay of 40ms, high-passed at 200Hz and low-passed at 7kHz. Put the pad wet-dry at about 50 percent, which is far more than any other genre here wants.
  • MelodyFour or five notes on an FM or wavetable patch, delayed by a dotted eighth, and let the delay do the rest of the phrase for you.
  • DynamicsDo not master this loud. Leave twelve decibels of headroom and let the arrangement handle intensity, because a limiter will flatten the entire point of the record.
