Whoops, the example was based on F at 120bpm, so a two steps would equal 14.37 bpm increase. And you can't mix raw numbers. It's a percentage game for bpms and cycles per second. Anyway, the funny thing is that someone like me is rocking hard math on this. I'm a huge fan of the African "2 on 3" found both in South African Soweto Jive and Ghanian Drumming, and I also like a lot of the current tracks created by folks bending temprament and scales without necessarily knowing what their doing. Music is not a science, and it breathes just as much as we do. In fact, my own blood pressure probably has more effect on the way something sounds than whether it's off CD, vinyl, or high-quality mp3. It's fun to dig into the theories, but at the end of the day... Either it kick, or it doesn't. -- There4IM (P.S. We need more dj's willing to experiment and play unlike tracks together. How do you think we _got here_?)
