What is Harmonic Mixing?
Also called: mixing in key
Harmonic mixing is a DJ technique of choosing and blending tracks whose musical keys are compatible, so the transitions sound smooth instead of clashing.
During a long blend, two tracks play at once. If their keys clash, the overlap can sound out of tune even when the beats are perfectly matched. Mixing in key avoids that and lets you hold blends longer and layer vocals over instrumentals.
Most DJs use the Camelot wheel or the circle of fifths to find compatible keys, and key detection software to tag their library. Changing the pitch of a track with key lock or pitch shifting can bring two nearby keys together.
Key is only one factor. Energy, tempo, groove and the mood of the room usually matter more, and a well timed key clash can be a deliberate effect.
