Man, I love this song. I can't help but dance. Why is that?

....

That's it! I know what we are gonna do today!

Music is known to stimulate pleasure, and reward areas like the orbitofrontal cortex, located directly behind one's eyes, as well a midbrain region called the ventral striatum.

Ferb, do you know what this means?

*BLINKS*

I knew you'd understand, Music can carry powerful emotional connotations. Beats automatically motor areas of the brain, according to magnetic resonance imaging studies, and propel our bodies to move spontaneously to the rhythm.

Therefore, fast-tempo songs are directly associated with more energy, movement, and dancing. Which are typically linked with being in a joyful state.

Whatcha doing?

I am trying to figure out why music makes us dance, there is gotta be some sort of math behind it.

Well of course silly, Jolijs feel good index and logarithmic harmonics are all about it!
