What is Harmonic Mixing?

Harmonic mixing is a technique used by top DJs to blend songs that are in compatible keys. By mixing tracks that are in the same or related keys (like 8A and 9A on the Camelot Wheel), you avoid clashing melodies and create smooth, musical transitions that keep the energy flowing on the dancefloor.
