Blend
A blend is a transition where both records play together for a stretch — long enough that the overlap is part of the music rather than a join between two pieces of it.
Measured in our catalog
Across 7,243 transitions sequenced by hand here, the median energy gap between adjacent tracks is 4 points on a 100-point scale — DJs blend into records that feel almost identical.
Tempo tells the same story: a median gap of 1.0 BPM and 81.5% within 3. A long blend is not something you rescue with technique, it is something you set up by choosing a near neighbour — and the corpus says that is exactly what experienced DJs do, transition after transition.

Measured on 11 August 2026 across 7,243 adjacent transitions in flows sequenced by hand on Mixgraph (saved flows only, machine-generated running orders excluded, both tracks analysed). Method: the full transition dataset and its chance baseline.
Why it matters
A blend is the technique that makes a set feel continuous instead of sequenced. Done at length it produces something neither record contains on its own, which is the closest DJing gets to composition and the reason a good one is remembered.
It is also the most demanding transition to hold. Every bar the two are together is another bar in which the tempos can drift, the basslines can collide and the phrasing can slip, so the length you can sustain is set by how compatible the pair actually is rather than by how long you want.

Suggestions are scored on how well a pair holds together, so the records offered first are the ones a long blend is possible with.
Frequently asked
How long should a blend be?+
As long as the two records tolerate. Sixteen to thirty-two bars is common in house and techno; two busy arrangements will not survive that and want a shorter overlap or a cut.
What is the difference between a blend and a cut?+
A blend overlaps the two records for a stretch; a cut swaps them on a single beat. A blend is smoother and riskier, a cut is instant and unforgiving of bad phrasing.
Why does my blend sound muddy?+
Almost always two low ends at once. Roll the incoming track’s bass off completely and hand the low end over in one move at a phrase boundary rather than letting both sit there.

Cut
A cut swaps one record for another on a single beat, with no overlap. It is the fastest transition there is and the only one that works between two records with nothing in common.
Transition
A transition is the move from one track to the next — the overlap where both are playing and the point where the first is gone. It is the unit a set is actually built from, rather than the tracks themselves.
Trainwreck
A trainwreck is a transition that falls apart in public — beats drifting out of phase, two basslines fighting, the floor noticing. Every DJ has had one, and most of them start with tempo rather than with key.
Chemistry
Chemistry is Mixgraph’s score for how well two tracks mix, from six weighted dimensions: harmonic key, tempo, energy, groove, mood and vocals. It rates the pair, not either track on its own.
