Score my transition

Pick two tracks from the catalog and see how well they actually mix — harmonic, rhythmic, energy and vocal compatibility, the technique that fits the pair, and a deep-link into the full key-pair guide.

How this score works

The chemistry score is the weighted average of four independent dimensions, each measured directly from the catalog audio profile of both tracks. No opinion, no editorial bias — just the math.

  • Harmonic — distance between the two Camelot keys on the wheel; same-key, ±1, and relative major/minor score highest.
  • Rhythmic — BPM proximity, with half- and double-time relationships recognised so half-time pairs aren’t punished.
  • Energy — delta in measured energy, normalised so a deliberate lift or ease still scores well.
  • Vocal — instrumentalness compatibility, flagging vocal-on-vocal overlap risks.

FAQ

How is the chemistry score calculated?⌄
Four dimensions weighted equally: harmonic (Camelot key relationship), rhythmic (BPM proximity), energy (catalog energy delta), and vocal (instrumentalness compatibility). The overall score is the weighted average; the breakdown shows each dimension independently so you can see which dimension is driving the verdict.
What kinds of tracks can I score?⌄
Any track in the Mixgraph catalog — 162,000+ tracks across electronic, dance and adjacent genres, all scored on the same six audio dimensions. If a track is not in the catalog yet, request it via the track request form and we will add it.
What does a low score mean — should I always skip those?⌄
A low score means the pair will not blend cleanly without intervention. Some of the most memorable transitions in a set come from purposely-distant pairs (tritone moves, half-time bridges) that succeed because they are planned. Treat the score as data; let it inform whether a pair needs cover (a breakdown, a filter sweep) or whether you should pick a different next track.
Can I share a score with my friends or audience?⌄
Yes — every scored pair has its own shareable URL. Click the Share button below the result; the link includes both track IDs so anyone visiting it sees the same score with the full breakdown.
