"Energy boost mixing" is a great technique to create energy on your dance floor.
Here is how to use it: Detect the key of your current song, and pick the next song to be 1 or 2 semitones above it.
If you're in C Minor, your next key should be D-flat Minor (+1 semitone) or D Minor (+2 semitones). Take a look at the image above. The rule is always the same, just go "right" on the piano from your original key.
The effect is really interesting: Energy on the dancefloor will rise every time. It doesn't work with every song, but most of the time it can create a pleasant effect.
Does this translate to Camelot numbers?
Yes. To go up one semitone, add 7 to your current Camelot number. If you're in E-flat Minor (2A), add 7 and you'll be in E Minor (9A).
To go up two semitones, just add 2 to your current Camelot number. If you're in C Minor (5A), add 2 and you'll get D Minor (7A). Play your next tune in 7A, and you'll experience an energy boost mix.
Who uses it?
I've heard Sasha and Armin Van Buuren use this technique many times. I personally love mixing +2 semitones since it does not clash as much as mixing +1 semitone. Every DJ should try this mix: The effect is really interesting.
