Tutorial 5 — Harmonic Mixing (Mix in Key)
Goal: blend tracks whose musical keys go together, so the mix
sounds smooth and emotional instead of clashing. This is "harmonic mixing." Pro software shows you keys; GoDJ
actually tells you whether the two you've got work together, and colours your track list so you
can pick a good one.
Turn the coach on in Settings → Training → Show Harmonic-mixing coach (on by default).
The Camelot wheel (the quick version)
GoDJ analyses each track's key and shows it in Camelot notation: a number 1–12
plus a letter — A = minor, B = major (e.g. 8A, 11B).
The rules:
- Same key (
8A → 8A) — perfect.
- Relative major/minor (
8A ↔ 8B) — same number, switch letter.
Smooth, shifts the mood.
- One step on the wheel (
8A → 7A or 9A) — same letter,
±1 number. Smooth.
- Two steps (
8A → 10A) — an energy move; works if you
blend quickly.
- Anything else — a clash; avoid, or only over a breakdown.
The HARMONY row
HARMONY A 8A Am B 9A Em Adjacent keys (one step) - smooth blend
It shows both decks' keys and a verdict, colour-coded green (compatible),
amber (energy/diagonal — use care), or red (clash). It names the relationship
so you learn the rules as you go.
Picking a compatible track from the list
While a track is playing, the library colours two columns for every other track, relative to the
playing deck:
- BPM cell — green = easy to beatmatch (within ±16%, half/double-time aware), amber = a
stretch, red = out of range.
- KEY cell — green = harmonically compatible, amber = energy/diagonal, red = clash.
A row that's green BPM + green KEY is an ideal next track.
Step by step
- Get a track playing. Scan the list and pick a track whose Key cell is green
(and ideally BPM green too).
- Load it to the other deck. Check the HARMONY row — it should read green.
- If it's amber, keep the blend short. If it's red, mix over a breakdown or
pick another track.
- Combine with phrasing: in key and on the phrase = a polished mix.
Tips
- Up the energy by going +1 on the wheel (
8A → 9A) or to the
relative major (8A → 8B).
- Keys are estimates — trust your ears. If green sounds off, re-analyse the track (right-click
→ Re-analyze).
Common mistakes
- Ignoring key entirely. Two clashing keys in a long blend sound sour even if the beats are
locked.
- Forcing a red pair. If you must, do it fast and over a section with little melody.
