To use Harmonic Mixing techniques, you need to know the key of the music you want to play. Our market-leading software scans your collection and matches the results to our groundbreaking Camelot EasyMix system . It tells you what key your song or sample is in, and what will mix best with it. You don’t even need an understanding of keys or music theory… it’s as easy as 1, 2, 3

We’ve been developing this software for over a decade, and independent tests consistently show Mixed In Key to be the most accurate key detection system on the planet. These days, most DJ software comes with an in-built, inferior system of its own, yet Mixed In Key remains the ultimate choice for the world’s top DJs. We’re the original and best key detection software available.

Doesn’t my DJ software come with Mixed In Key?

In a word, no. Some DJ software uses our Camelot system, but you will only find the accuracy and peace of mind that comes from our Mixed In Key algorithm by downloading our software direct. Mixed In Key will instantly feed your results to your DJ software, giving you the most accurate key information possible and ensuring your mixes are spot on.

Spin the wheel

It’s so simple. Mixed In Key tells you at-a-glance which tracks and sounds will work together. You can stick to the exact same key, ie 5A to 5A, or move through the gears in a harmonically pleasing fashion. 5A can go to 4A, 6A or 5B smooth as a knife through butter. Here’s how that works:

Camelot Wheel

This is the Camelot Wheel. Each musical key is represented by a number and letter combination. The outer ring has Major Chords, while the inner ring shows Minor Chords. Our Camelot Easymix system makes navigating through keys as easy as counting up and down.

Up, Down, Around.

Key matching matters because it makes the music sounds like it belongs together. You could, therefore, stick to the same key for your whole set and everything would sound ‘correct’. But after a while it would get pretty boring. Liven things up by moving around the Camelot Wheel – go up or down one increment in a straight line on the wheel and you’ll sound great. Check it out: 8A goes to 9A or 7A, because they’re one number up/down on the wheel, in a straight line from 8A.

Example of Harmonic Mixing Rules with the Camelot Wheel and Mixed In Key

Mixing from inner circle to outer circle

For a pleasant harmonic mix, you can keep the same number, but change the letter. For example, 8A goes with 8B because the number 8 is the same. You can mix between them.

That gives you four great options. If you’re looking at your Mixed In Key results and trying to decide what song to play next, look for something that’s adjacent to your current Key Code. All of those songs will be harmonically compatible.

Get creative

So you’ve nailed the basics – you can mix up and down on the Camelot Wheel and are loving the results. But don’t be fooled, there’s more to it than meets the eye. Try plotting your way clockwise or anti-clockwise around the wheel… nice, right? Moving in this kind of sequence keeps your set sounding harmonically pleasant, fresh and dynamic. You can even go wild and drop in occasional curveballs. Some top DJs will grab their audience’s attention with a crazy move like slamming a mix from a 3A track to a 9A track. It sounds pretty brazen, and should be used with extreme caution, but goes to show how creative you can get when you master Harmonic Mixing!
