so, in science and music, we finally get to the awesomer stuff! we learned that pitches are not just sound waves in the air. if you have a regular rhythm, and speed it up, eventually, you get a pitch. and you can combine rhythms to get intervals! An interval of a fifth has a 3:2 ratio of the frequencies of the notes of the fifth, but it can also be formed by a 3:2 ratio of rhythm -which means if you have someone tapping triplets and someone else tapping eighth notes, speeding that up will produce a fifth when we get past the point that our ears cannot distinguish the rhythms, and instead, perceive them as pitches! wow. super long, totemo luosuo de sentence….
the gift certificate i received is only good for entertainment stuff, not clothes. sad.
oh, right. i forgot to mention the flaming speaker. so, the science&music professor hooked up his iPod to a hollow tube. somehow, there’s gas pumping through the tube. the top of the tube has a row of holes, like a wooden flute. he lights a tiny flame in each of the holes, so when he turns on the iPod and plays music, the music is transmitted into the tube, varying the (gas distribution, flow?)idk, but you can see a wave of the little flames, growing shorter and taller. think: little flames=people’s arms doing the wave in a stadium. that’s what it looks like. and when the bass line beat out the rhythm, the flames flickered in time with the beat, and had especially dramatic flickers when there was an accent. wish i took a video of it and could post it. it was truly music+physics.
