Techno Production & DJing Glossary
Clear definitions of the terms every techno producer and DJ should know, written by the Seedj team and linked to the courses that teach each technique.
- 909 kick
The 909 kick is the kick drum sound of the Roland TR-909 drum machine: an analogue-synthesised drum built from a pitched body with a fast downward pitch envelope and a clicky attack. It is the most influential kick sound in techno and house.
- Acid bassline
An acid bassline is the squelchy, resonant bass sound created by the Roland TB-303 synthesizer, defined by a sawtooth or square wave run through a resonant low-pass filter whose cutoff is modulated while notes slide into each other. It defined acid house and remains a staple flavour in techno.
- Beatmatching
Beatmatching is the DJ technique of adjusting the tempo and phase of two tracks until their beats align, so one can be mixed into the other without a rhythmic clash. It is the foundational skill of club DJing.
- Clipping
Clipping is what happens when a signal exceeds the maximum level a system can handle and its peaks are cut off. Hard clipping slices peaks abruptly; soft clipping rounds them. Used deliberately, clippers are a core loudness tool in techno — especially on kicks.
- Cue points
Cue points are saved position markers in a track — set in software like Rekordbox, Serato or Traktor — that let a DJ jump instantly to prepared moments: the first beat, a build, a drop or a mix-out point.
- EQ mixing
EQ mixing is the DJ technique of using the channel equalizers — typically low, mid and high bands — to blend two tracks by swapping frequency ranges between them, most importantly never letting two basslines play at full level simultaneously.
- Four-on-the-floor
Four-on-the-floor is a drum pattern in which the kick drum hits on every quarter note of a 4/4 bar — the steady "boom, boom, boom, boom" pulse that underpins techno, house and most club music.
- Groove and swing
Groove is the rhythmic feel of a track — how its hits relate to the grid and to each other — while swing is the specific technique of delaying every second subdivision so the pattern lopes instead of marching. Together they decide whether a loop feels alive or robotic.
- Hoover sound
The hoover is a growling, sweeping synth sound — originally from the Roland Alpha Juno's "WhatThe?" patch — famous from early rave and hardcore, and revived heavily in modern hard techno leads and basses.
- LFO (Low-Frequency Oscillator)
An LFO (low-frequency oscillator) is an oscillator running below audible frequency that is used not as a sound but as a modulation source — automatically moving parameters like filter cutoff, pitch, volume or pan in a repeating cycle.
- Low end
Low end refers to the bass region of a mix — roughly everything below 150–200 Hz, where the kick and bassline live. In techno, controlling the low end is the single most important mixing skill, because the genre's impact depends on it.
- Mastering
Mastering is the final processing stage of a finished stereo mix — EQ, compression, saturation and limiting applied to the whole track — to make it loud, balanced and translatable across club systems, streaming platforms and headphones.
- Modular synthesis
Modular synthesis is sound creation using separate hardware or software modules — oscillators, filters, envelopes, sequencers — connected freely with patch cables, so the signal flow itself becomes a creative decision rather than a fixed architecture.
- Phrasing (DJ mixing)
Phrasing is mixing tracks so their musical sections line up — starting a transition at the beginning of a 16- or 32-bar phrase so that builds, drops and breakdowns of both tracks land together instead of colliding mid-section.
- Rave stab
A rave stab is a short, bright, chord-based synth hit — originally sampled from classic synths and sped-up piano/organ chords in early-90s rave music — used as a rhythmic and melodic accent in techno, hard techno and hardcore.
- Resampling
Resampling is recording the processed output of your DAW (or a track within it) back in as new audio, so you can edit, stretch, reverse and re-process the result as raw material — a cornerstone technique of electronic sound design.
- Rumble bass
A rumble bass is the low, reverb-saturated bass layer that sits underneath the kick in techno, created by sending a kick into distorted reverb and filtering the result so it fills the low end between kick hits. It is the signature of rolling, hypnotic techno.
- Saturation
Saturation is a mild, musical form of distortion that adds harmonics to a sound by gently overdriving it — emulating analogue tape, tubes or transistors — making elements sound warmer, denser and more audible on small speakers.
- Sidechain compression
Sidechain compression is a technique where a compressor on one sound is triggered by a different sound — most commonly ducking the bass every time the kick hits — creating both a cleaner low end and the rhythmic "pumping" feel central to techno and house.
- Sound design
Sound design is the craft of creating and shaping the individual sounds in a track — through synthesis, sampling, layering and effects processing — as opposed to composing the notes those sounds play. In techno, where tracks use few elements, sound design largely is the music.
