Double Drop: when the DJ manages to mix two tracks reaching the drop at the same time in both of them, thus letting the crowd go bonkers.
Usually, drum & bass DJ sets are rather always double dropped, it’s part of the jungle culture and mixing style. It takes a bit of know-how, though. First of all, even if all the tracks are subdivided in 4 movements per bar, one could have an intro of 30 seconds and another one of 42 seconds, so it’s not simply playing them together. Then, another problem could be the key of the track: for example, a track in G will mix good with a track in G, C and D, due to the musical theory of the chords and the circle of the fifths. However, it is usually a good practice to double drop a certain number of tracks in the same key and then mix another track which is not in the same key in a different manner, maybe looping a region of the song where there are mainly drums (which have no key). A schematic of the circle of the fifths is reported here, and even if (sadly) most DJs don’t know a lot of musical theory, one must remember as a sort of rule that every key in the circle mixes properly only with the two adjacent ones.
To realize a good double drop, one should know the songs very much. He (or she) must know when the drop comes, in order to delay it with a loop waiting for the other track to reach. This sounds trivial, but it’s not. Do you think you really know how many bars are there before your favourite jungle tune drops? I guess 90% of you do not. Usually, one double drops the tracks he knows the most, because he can manage it. For example, try imagine a double drop between these two massive neurofunk tunes, which I usually double drop in DJ sets:
Both tracks come from Noisia and their Vision label, so they have a similar touch in the drums, a similar sound and groove in the synths. This facilitates the double drop issue, and must be taken into account. Moreover, they are in similar keys, which means that they properly mix together. Another thing that enforces the double drop impact on the crowd is the ability to let ’em know what you’re about to DD. Let them smell it, then let them crave for it, then give ’em the meal.
To have an idea on how to double drop two tracks, take a look at the tutorial below! The DJ is a bit of a crazy guy with some serious mental issues but he knows shit. Meanwhile, I hope you understood that DJing is not simply pressing play, but involves a lot of knowledge that sadly a lot of people do not have. Hopefully, the jungle is still massive.
