Because the same elements occur across all genres of this style it's quite easy to get confused as to what is what. With the boom of technology, pretty much anybody with a midi controller and DAW (digital audio workstation) can start producing bass music. They then label it wrong and promote it all over the internet as dubstep when it may actually be drumstep, or neurofunk or neurohop.
Unlike other genres of music, this division of dance music is actually very easily identified. The quality that defines this type of music, is strangely enough, the tempo or the speed of the song. Here is a list of the most popular types of bass music and their tempos:
1. Dubstep is pretty much always at 140 BPM but drums are in half time which makes it feel a lot slower. The drums are usually swung as well. The kick and snare drum hits on every other beat. Artists include, Culprate, Nero, Flux Pavilion and Datsik.
2. Complextro is also at 140 BPM but the drums are not halved so it seems a lot faster. It's basically house music on steroids. The kick and snare drum hits on every beat instead of every other beat. Porter Robinson is a great example of a complextro artist.
3. Drumstep is typically at 160-170 BPM but the drums are also halved and highly syncopated giving this genre a groovy hip hop feel. Some artists include Noisia and Pendulum.
4. Drum and Bass is Drumstep's brother and shares the exact same qualities except the drums are kicking at full speed. Many drum and bass artists make drumstep so checkout Noisia and Pendulum once again. Camo and Krooked is another great artist to check out.
5. Moombahton and Moombahcore are set to a tempo of 110 BPM and incorporate elements of reggaeton. This genre is basically house music at a slower tempo.
6. The newest subgenre is neurofunk which is also sometimes called neurohop and can be mistakenly called glitch hop. This style is typically at about 90-100 BPM and incorporates swinging, syncopated drums with heavy modulated bass along with funky basslines and synths using notes of the blues or pentatonic scale. Neurohop has more of a hip hop feel than a funk feel but often times the two genres are combined.
So there you have it. Now you can pick these differences out like a pro and help others discern betwixt the two (don't you just love that word?) Dance on.
