Key & harmony
Mode
A mode is a scale started from a different note of the same set — Dorian, Phrygian, Mixolydian and the rest. Major and minor are two of the seven, and the other five turn up more in club music than people expect.
In practice
A detector calls every mode major or minor. When a "minor" record sounds unexpectedly bright, this is usually why.
Dorian and Mixolydian are the two you will meet most — Dorian is a minor scale with a raised sixth and turns up constantly in house and disco, Mixolydian is a major scale with a flattened seventh and is most of funk. Neither has its own Camelot code, so both hide inside the label a detector gives them. You do not need to identify them to mix; you need to know that the key field is a simplification, so trust your ears when two records the wheel approves of still disagree.

Why it matters
This page is about the musical sense of the word. Slip mode, vinyl mode and export mode are unrelated player and software features with their own pages, and the collision is worth stating plainly because the word is doing three jobs in a DJ booth.
Modes matter to mixing because a detector reduces them all to major or minor. A Dorian track gets labelled minor, which is close enough for the wheel and not close enough to explain why it sounds brighter than the other minor records around it — that raised sixth is doing the work, and no key field records it.
Frequently asked
Is this the same as slip mode or vinyl mode?+
No — those are player features and have their own pages. This is the musical sense: a scale started from a different note of the same set.
Why does a minor track sound bright?+
It may be Dorian rather than natural minor — a raised sixth, which lifts the whole thing. A key detector labels it minor because that is the closest of the two options it has.
Do modes break harmonic mixing?+
No, they just make it approximate. The wheel still gets you to compatible records; the modes explain why two approved records occasionally still disagree.

Scale
A scale is the ordered set of notes a piece of music draws on. Major and minor are the two that dominate club music, and which one a track uses is half of what its key name tells you.
Musical key
The musical key is the note a track resolves to plus whether it is major or minor — A minor, F major. It is the same information a Camelot code carries, written the way a musician would write it.
Slip mode
Slip mode keeps the track running silently underneath whatever you are doing to it. When you release a loop, a scratch or a reverse, playback jumps to where the record would have been if you had never touched it.
Harmonic mixing
Harmonic mixing means choosing the next track by key as well as tempo — staying on the same Camelot code, moving one step around the wheel, or swapping between the major and minor of the same number.
