All music can be analysed according to the interplay and relative amounts of 4 qualities. The Groove. The One. Complexity. Randomness. I've done this before but I'm going to do it again. The Groove is what entrains the brain and body into moving in time with the music. It's what gets the crowd dancing in time with the rhythm. Without the groove or with a groove which keeps changing too often you get lost. It's why Funk works so well and Jungle can be hard to listen to. The One is the build up to the crescendo that resolves into a new beginning. It's the "rip your pants off moment". It's the point where the cycle ends and the new cycle begins and everybody gets back in sync. It builds and builds and then goes "and... one". Complexity and randomness are more subtle. If there's not enough complexity music gets boring. It's tricky to pull off. Music can be complex even with a 3 piece. But usually it's about depth and the hidden cow bell with reverb that you only hear after the 6th listen. Randomness is what keeps the music new. Dub is full of randomness. It's the floaty echobaby'd trumpet that makes you go "WTF?". Now look at some styles. House and Trance are all groove, lots of one but not much complexity and no randomness. donk, donk, donk. Dub Reggae has the groove and randomness but it's missing The One. Miles Davis free form Jazz (In a silent way) has no groove or one but loads of complexity and randomness. It's like he's saying "you know where the Groove and One are, you do it, because I don't want to". Classic Funk has the Groove and The One in spades. They get the complexity by layering more and more instruments. They then add the randomness by "pulling" the beat or in Parliament/Funkadelic's case by invoking the mothership. Mainstream pop tries to fake the groove by over compressing the sound and then adds a gratuitous One while the predictability of it all removes the randomness. and so on. The Groove. The One. Complexity. Randomness. Got it?
