Harmonic Mixing is an advanced technique used by top DJs all over the world. By mixing tracks that are in the same or related keys you can eliminate key clashes. Many professional DJs move around the Camelot wheel with every mix. If you are not sure how to find the key of a song you could try using Mixed In Key software.

To select a compatible song, choose a keycode within one ‘hour’ of your current keycode. If the song you are playing is in 8A (A minor), you can play 7A, 8A or 9A next. If you are in 12A, you can play 11A, 12A or 1A. This mix will be smooth every time.
You can also mix between inner and outer wheels if you stay in the same ‘hour’. For example, try mixing from 8A (A minor) to 8B (C Major – the relative Major) and notice the change in melody as you go from Minor to Major.
Harmonic mixing is a simple technique, but it opens up a world of creativity.
