How to Make Dancefloor DnB: Arrangement Tips from DC Breaks (Plus a Sub Focus-Style Lead)

Dancefloor drum and bass lives or dies on its arrangement: a drop that keeps its energy, a second section that moves on, and a breakdown that resets the room. Here is how Dan from DC Breaks turns a sketch into a structure in Logic Pro, from rewinding the drop to reprogramming chords and writing new melodies, plus a dancefloor lead in Serum inspired by Sub Focus. Everything comes from two of our own videos, with screenshots and audio.

DC Breaks’ arrangement video for DNB Academy, taken from their start-to-finish course: Dan works on the track “Sunshine” in Logic Pro. The lead section further down uses our Sub Focus-style lead video.

1.Start from a sketch with a drop

Don’t arrange an empty project. DC Breaks start this stage from a sketch that already has an intro, a build and a first drop, then shape the rest of the track around it.

The “Sunshine” sketch was created in earlier videos of the course, and Dan’s partner Chris had pushed it in his own direction before handing it back. The project runs at 174 BPM. Every part lives in a folder: Pads, Drums, FX, VOX, Bass, Arps, Plucks, Lead and chords, plus an “OLD PARTS” folder for ideas that were taken out (watch at 0:53).

The layering is a lesson in itself: something new arrives every 16 bars, so the energy rises steadily into the drop. “See, this is why we use folders,” Dan says while moving parts around: “it’s really easy to lose your way” (watch at 6:02). Keep removed parts in their own folder instead of deleting them, because DC Breaks pull several of them back in later.

2.Decide what follows the drop: roll out or rewind

After the first drop you have two options in DC Breaks’ workflow: a roll-out section that winds the energy down into the breakdown, or a “rewind” straight back into the start of the drop so the energy keeps going.

A roll-out is “mainly the beats and the bass and a few melodic things”, to take the track down into the breakdown before building back up to the second drop. The other option, which Dan says they do “quite a lot of these days”: when you reach bar 81, rewind back to bar 49, the start of the drop, “so you keep the energy going” (watch at 3:06). That is the route he takes here.

In practice, the second pass through the drop is a copy that changes over time (steps 3 to 7). How long each section should be, and how the classic intro-drop-breakdown-drop-outro layout adds up, is covered in our drum and bass song structure guide, so we won’t repeat it here.

3.Reprogram parts that no longer fit

When one part changes, check everything that plays with it. Here a new, more melodic bassline left the old vocoder chords out of tune, so Dan reprogrammed them as simple two-note chords.

Dan wanted the vocal back in the second section, but Chris had run it through a vocoder, and since the new “melodic bassline that moves around a bit” arrived, the vocoder was “not actually playing the right chords anymore” (watch at 4:00). On screen, the vocoder track is Logic’s EVOC PS followed by Bitcrusher, played from a MIDI part of two-note chords written to follow the bassline (watch at 4:58). “That’s obviously much more in tune.”

Pulling the new bassline (“Mid Bass 2”) into the vocoder section also gave Dan an idea: it “sounded quite cool low down”, so he saves it for the breakdown (step 5).

4.Remove, add or replace elements in each section

A rewound drop can’t just repeat. Change what plays in each section, removing some parts, bringing others back and replacing a few, so the track feels like it is moving forward.

The second section “has got quite a lot going on”, so Dan starts muting: the leads go (“we’ll bring them back in that last section”), and he tries the plucks with and without (watch at 6:23). On screen the Lead folder holds a simple lead, verb leads and a pluck verb, which can be switched on and off section by section.

Dan doesn’t fix everything at once either. The vocal “sounds a bit ropey”, so he notes it and moves on: “if there’s time I will address it”. Arranging is about the big picture first; details can wait.

5.Park ideas for the breakdown as you find them

When a sound would work somewhere else, move it there straight away. Dan copies a modulated pad and the low bassline to the breakdown area, “just in case I forget, which happens all the time”.

Digging through the project he finds a pad with modulation from LFOTool and decides it “sounds pretty cool for the breakdown as well”, even though the project doesn’t reach that far yet (watch at 7:06). On the Sunshine pad, LFOTool runs its SVF LP filter at a 1/8 rate with a rising curve, routed to cutoff and resonance, after a Pro-Q 3.

Parking ideas like this means the breakdown is half-written by the time you get there, with sounds that already belong to the track.

6.Introduce new melodies in new sections

A new section needs something new to keep the energy up. DC Breaks rehash an idea from the original sketch: the same Serum patch, with new movement on its pitch, playing a new melody.

“I’d always be rehashing these kind of things where possible,” Dan says, reopening a Serum part from the original idea (watch at 8:55). He takes out the old pad sample, then drags LFO 3 onto the oscillator semitone control, draws a slightly different shape and sets it to a half bar speed (1/2 on screen) (watch at 10:00). Bypass it and you hear the old line; switch it on and “I’ve got a new melody there”.

It is a quick way to write variation that still fits: the patch, the key and the rhythm stay familiar, and only the movement is new. Our bass patterns tutorial uses the same principle for drop basslines: keep the rhythm, change the sounds.

7.Reuse elements through the arrangement

Reusing a fill, a roll or a sound in more than one place ties the track together. Dan copies his snare roll to the drop as well, then copies the whole drop section across, automation included.

“Quite like my snare roll, so I’m going to keep that in. Do you know what, I’m going to stick it at the drop as well, just see what happens” (watch at 10:50). He then “very crudely” grabs the section and copies it over, checking that the automation comes with it, and plays the result.

By the end of the video the structure has moved on: the drop, the rewound section from bar 81 with the full lead back in, a riser, then a breakdown at bar 97 with the pads and no drums. “I think the breakdown’s quite cool, and I’m liking where it’s going structure-wise.”

8.Bonus: a dancefloor lead in the style of Sub Focus

Big, vocal-sounding leads are a dancefloor DnB signature. Our recreation of the lead from Sub Focus’s “Solar System” builds one in Serum from a supersaw, a moving band-pass filter and plenty of effects. It’s our own take for learning, inspired by the track.

Our Sub Focus-style lead tutorial in Serum: a recreation by DNB Academy, inspired by “Solar System”.

Oscillators. From an init saw, turn the unison right up (16 voices on screen), add a second oscillator with the same settings and put both one octave down. Layer in some noise (AC hum1 on screen). Then add a small pitch bend: an LFO in envelope mode on the oscillators’ coarse pitch, made unipolar (hold Shift and Alt and click the modulations) and set at around -9 (watch at 0:41).

Filter. A band-pass filter creates the “vocal movement” of the lead (BN 12 on screen, with both oscillators and the noise going through it). Route LFO 2 to the cutoff, increase the resonance, map it to the filter’s Freq control so the notch moves from high to low, reshape the LFO and switch it to envelope mode too (watch at 1:37).

Effects. The band-pass takes away highs, so the effects add them back: Distortion on Stomp Box with the drive boosted (64% on screen), a multiband compressor and an EQ boosting the highs. A second EQ band gets the same LFO on its frequency to push the vocal feel further (9.3 dB of gain on screen). Then a delay with “super long tails”, but filtered, and a Hall reverb with the mix boosted (38% on screen) (watch at 2:51).

Final EQ. After Serum, an EQ boosts whatever needs it. In the video that is the highs and the area around 1 kHz: on Ableton’s EQ Eight, a peak near 1 kHz and a high shelf at 6.67 kHz, +8.80 dB (watch at 4:50).

To get the last 10%, experiment with the LFO shapes, the filter cutoff (which changes the vocal movement) and the unison detune. Then try the lead in your own drop: it is exactly the kind of sound Dan mutes in one section and brings back in the next.

Common dancefloor DnB arrangement mistakes

• Arranging before the drop works. Get the main idea right first, then build the structure around it.
• Repeating the drop unchanged. If you rewind into the drop, remove, add or replace parts so the second pass moves forward.
• Keeping parts that clash. When the bassline changes, check the chords, vocoder and pads against it and reprogram them.
• Deleting old ideas. Keep them in an “old parts” folder; DC Breaks pull several back in.
• Waiting to place breakdown sounds. Move a good pad or bassline to where it belongs as soon as you hear it.
• No link between sections. Reuse a roll, a fill or a sound across the track so it feels like one piece.
• Polishing too early. Note small problems, like a ropey vocal, and fix them once the structure is done.
