How a psytrance track is structured

A psytrance track is built to keep a dance floor moving for seven minutes or more. That only works if it changes all the time without losing the groove. Here is what a track is made of and how its sections fit together.

The building blocks

Kick and bass are the engine. The kick plays a steady four-to-the-floor pattern, and the bass rolls in the 16th notes between the kicks. The bass is usually a saw or square wave through a filter, with modulation that keeps it moving over long stretches.

Percussion adds drive and detail: off-beat hi-hats, claps or snares to mark important moments, and extra percussion loops for texture.

On top sit leads and pads. Leads carry the hooks and often contrast with the bassline, pads fill the background and slowly change through filtering and reverb. Effects such as delay, reverb, flanger and phaser are part of the sound itself, not decoration: they give the track its depth and its psychedelic movement.

Start from a loop

A practical way to begin is a loop with kick, bass and one simple percussion element. If that groove works on its own, the rest of the track has something to build on. Then add sounds that each have their own frequency range and role: a mid-range lead for the melody, pads for space, small effects and one-shots for detail.

Psytrance is arranged in phrases, usually 8 or 16 bars long. New elements, changes and transitions land at the start of a phrase, which makes the track easy to follow on the dance floor and easy to mix for a DJ.

The sections

• Intro: sets the mood and gives DJs room to mix in. In most dance floor tracks it starts with the kick and some percussion and adds elements step by step, so the next track can be blended in cleanly.
• Build-up: the energy rises. More percussion comes in, filters open, and risers that climb in pitch and volume point towards the peak.
• Drop or main part: the full groove with kick, bass, leads and all layers. Briefly removing elements just before it makes the return hit harder.
• Breakdown: the kick drops out and the track breathes. Atmospheric sounds from the intro come back, or a new melody appears. Then the percussion and a filtered bass rebuild the tension for the next drop.
• Outro: elements are taken out step by step, often down to kick and percussion again, so the DJ can bring in the next track.

Most tracks run through build-ups, drops and breakdowns more than once. Each round should bring something new, a changed bass pattern, a new lead or a variation of a motif, so the energy keeps moving forward.

Sound design that keeps things moving

Because the groove repeats for a long time, the sounds themselves have to evolve. A few common techniques:

• Combine oscillators: saw, square and sine waves layered or slightly detuned give a fuller sound.
• Modulate: an LFO or automation on filter cutoff, pitch or volume makes a sound pulse or sweep.
• Shape with envelopes: a slow attack on a pad's filter creates a swell, portamento on a lead makes the notes glide.
• Layer: a sub layer for weight and a mid-range layer for character, each doing one job.
• Add character: distortion and saturation add warmth and bite; chorus and flanger add width and movement.
• Sample: vocal snippets, found sounds and granular processing add textures you can't get from a synth alone.

Mixing with the structure in mind

The mix supports the arrangement. Set kick and bass first and keep them in the centre, high-pass everything else so the low end stays clean, and pan hi-hats, percussion and layers to the sides for width. Use reverb and delay with care: long reverbs suit atmospheric sounds, but too much washes out the rhythm.

Automation ties the sections together: a high-pass filter sweeping up during a build-up creates tension, and dropping it at the drop releases it. When you master, compare your track at the same loudness with releases you like, and take breaks so you return with fresh ears.
