Dancing and Physics
Lately I’ve been thinking a lot about dance music. I’ve been a DJ for 5 years now, and dancing for longer, but I’ve never taken a step back to ask exactly what it is about music that makes people want to bounce, shake, jiggle, or do whatever they do when a groovy tune comes on.
If my memory serves me correct, physics tells us that all objects have a natural frequency at which they resonate. My mind has been occupied with this phenomenon lately while in the club environment: is dancing merely the resonance of the human body? And if so, what is the natural frequency of the human body?
There are a plethora of dance music styles, with new genres popping up every day. Regardless of the style, most dance music tends to fall into a few natural modes: hip hop and downtempo tends to fall in the range of 60-80 BPM while techno and house are typically 120-140 BPM. Are these related to the natural frequency of the human body, or just stylistic constraints? I want to know.
One has to be careful though. If there is a unique frequency that makes most people bounce wildly, and this number were to fall into the wrong hands, the fate of dancers could be the same as some classic bridges and buildings. Yes, what I’m talking about is a dance track that resonates so much it causes all dancers to shake wildly until their arms and legs are ripped away from their torsos. As soon as I learn the magic frequency, the dance track of destruction will be mine I tell you, MINE! And all ravers will be subject to my control!
