DJ Knowledge – Learn The Language





Drop the Mic, feel the vibe, cut the loop, turn on the bass, high frequency… You’ve probably heard these terms, but what do they mean?

Before you buy any equipment or start any investment you better have some knowledge about the DJ and Music World. With the knowledge I’ve got and all the research I’ve made, I created for you a list (non exhaustive) to extend your knowledge.


Amp – Short terms for amplifier.

Ableton live – A software music sequencer and digital audio workstation

Acapella – A track containing only vocals.

Active (Studio Monitors) – Studio monitor speakers have a built-in amplifier meaning that they can be connected directly to mixing consoles or sound sources without the need for an external amp.

Auto Warp – An Ableton Live function that allows the program to calculate and time stretch music.


Balance Control – A control that adjusts the left/right balance of your sound.

Balancing Levels – this is a technique professional DJs used to make sure they get their music as loud as possible without it distorting or sounding rubbish. If you don’t know how to do this, the “sound manager” at a venue will have to turn you down in case you damage the “sound system”. Sometimes this is known as sorting the “Gain Structure”.

Bar – in dance music a bar is 4 “beats”.

Bass – The lower end of the Frequency range you can normally control on a Dj mixer.

Bassline – The driving force to most dance music Produced by Bass frequencies.

BPM Counter – A device used to automatically calculate the BMP of a track.

Break – 1) a bit of a song which sounds great and could maybe be used as a sample to make a new “hook” or “riff” with. 2) A change in a song where one or more instruments stops playing. 3) A change in a song where one instrument does something different e.g. a drum fill.

Crossfader Curve Control – A control that allows adjustment of the crossfaders fade curvature.

Cue –1) to prepare a song to be played. Normally a Dj chooses a point from which to begin a tune that is the beginning of the first beat of the first bar, or occasionally the beginning of the audio if these are not the same. More experienced DJs get creative by cueing from anywhere 2) to cue up can also be used to describe the action of setting an audio path so you can hear something in your headphones 3) on a CDJ, DVS or Controller deck the cue button is used to stutter the beginning of a song or to set a “cue point” which is where the song will begin to play from 4)On some DJ mixers the cue button for a channel will select that channel to be played through the headphones.

This often happens when the original mix is on an album and the extended mix is released as a single for playing in club settings.

Outro – The end of a song, often the same few words being faded out.


P.A. (System) – Another word for a “sound system” the initials P.A. used to mean Personal Address but also get confused with Power Amplifier. So P.A. actually means Personal/Public Address System. P.A. became the recognized nickname for all kinds of “sound reinforcement” equipment. A portable P.A. can be simply two speakers with internal amps while a P.A. (not prefixed with the word “portable”) normally means a larger “sound system” which will require a professional “Sound man” or “Sound Engineer” to set it up and control it.

Phones – nickname for headphones

Phono – phono level relates only to vinyl decks – be sure to put the cable from any vinyl player into a phono input on your DJ mixer.

Phono Cable – Also called RCA, the industry standard cable for DJ and home hifi equipment and I think we discussed this topic earlier.

Phrase – any bit of music you can hear repeating during a song, normally each instrument has its own phrase, the drums do a beat, the bass does a bass line etc. Each repeats the same thing during the chorus or verse but may change in the break/middle-8.

Platter or Plate – The top section of a turntable driven by its motor or belt.

Pitch – Sometimes confused with speed or tempo, the pitch of music is actually the frequency of the waveform which enables us to hear music. The pitch of a sound defines it’s note. A high pitch is a high note (the “chipmunk” vocal sound- effect is achieved by increasing pitch to very high levels). A low pitch is a low or bass note. On old record players if you increased speed or tempo you always increased pitch too so the speed control was called the “Pitch Fader”. Modern CD decks can alter speed without changing pitch but still sometimes call the tempo/speed adjuster the “Pitch Fader” because of the way it used to work.

Pitch control –The ability of a device to change the tempo of a song. This is very important if you are Beatmixing.

Pitch lock –The ability of a device to change the tempo of a song, without changing the pitch. This lets you drastically speed up songs with vocals without a “chipmunk” effect.

Pitch bend –The temporary changing of pitch to get beats in phase. Vinyl DJs typically use their fingers to speed up or slow down the record by pushing/pulling the record by the label. Some twist the spindle in the center to change the pitch momentarily. CD players offer this as buttons. Once the DJ stops bending the pitch, the decks will automatically snap back to the current pitch control settings. This is necessary since its possible for two songs to be playing at the exact same tempo yet have their beats out of phase. By bending the pitch momentarily, the beats come into phase and the DJ doesn’t have to worry about readjusting the pitch control.

Pitch Fader – the control used to alter the speed or tempo of music. See also “Pitch”

Promo – A pre-released version of a track.

Pulse – same as “beat.”


Re-edit – A version of a track produced by re-arranging and/or removing parts of the original. Unlike a Remix, which may change a track beyond recognition, a re-edit simply re-arranges the track’s parts – verses, choruses, Breakdowns etc. – in a different way.

Release – A collection of tracks released by an artist as a single piece. Examples of releases include albums, EPs, Singles etc.

Remix – An alternative version of a tune created by adding/removing track elements, layering samples and/or sound effects on top of the track as well as changing the key, tempo or other characteristics of the piece.

Requests – the public and the people dancing at clubs or parties may often request a song from the DJ. It depends on what type of request it is, what type of party it is, and what type of DJ you are whether you play it or not.

Reverb – Creates the effect that a track/sound is being vibrated or disturbed

Rewind – spinning the song back to the beginning to play it again because the crowd liked it.

Sound Manager – Another name for a sound engineer. Although instances may occur where a sound manager runs the system and a sound engineer runs the desk.

Sound Reinforcement – The term given to all the processes which are needed to amplify sound for projection at events. Sound reinforcement will require a “sound system” or “P.A.”

Sound System – The amplifiers, speakers, outboard units and crossovers that together create the sound in clubs and venues. Not in any way like a home HiFi or a portable P.A. The Sound System requires a “Sound Engineer” to correctly use it.

Spinback – Spinning the disc backwards to finish a mix with a flourish!

Stab – A short sound used as a sample, normally for scratching.

Strobe – A flashing light on a vinyl turntable that lets you check how precisely the deck is spinning. Under strobe light, the dots on the side of the platter are supposed to “freeze” on certain pitch positions.

Time Coded Vinyl – Timecode disks allow you to control your favorite DJ software with turntables or CDJ’s.

Throwing – Giving a record a little push when it starts up so you don’t have any lag time while it gets up to speed. CD players do this by featuring instant start. (normal CD players may take a few tenths of a second before a song starts) Throwing a record null the lag time while it accelerates from zero to 33ish RPM. It sounds silly at first but it is actually very critical for Beatmixing.
