Beat Jugglin'

It's all about the break. That's what the B in B-boy stands for. That's why it's called breakdancing. That's why hip-hop is what it is. See, back in the day, DJs would play two copies of the same record, continuously backing them up to play the same beat over and over. It was the beat that the dancers wanted to hear. Pretty soon, the MCs that were there to hype the DJ started to freestyle over the looped beats and a whole new style of music was born....Once you've got it down, try setting your loop point on the second snare instead of the first kick. You'll get a weird waltz thing going that way. Try throwing in a few scratches on the kicks too.
