00:00Check this, when you put your hand in front of a speaker, you can feel the air vibrating.
00:21That's because sounds of pressure changes, which cause tiny movements in the air, called
00:27waves.
00:28Watch the right, the first bit of air squashes the next bit, and the next bit, bing bang
00:32bong.
00:33Now here's where it gets really interesting, out of that and into this, once the waves
00:38reach your ears, the air moves your eardrum, which sends a signal along the nerve, and
00:43the music connects with your brain, and soul.
00:49This causes a mad reaction, which makes the body groove.
