It's no secret that Neil deGrasse Tyson is one of my favorite astrophysicists. So when I saw this morning that he was featured in the latest Symphony of Science video (along with Brian Cox and Carolyn Porco), I was overjoyed. But all the joys of symphonies aside, the real reason I'm posting this is to point you toward this piece Tyson did for NOVA scienceNOW explaining how autotune works. In a little less than seven minutes, we're shown the history of autotune, how it works its magic (with a good explanation of pitch and sound sprinkled in), and end on Tyson's singing corrected to a better note. I can't imbed the video, so check it out here.
If you love Tyson as much as I do and want to know when he tweets things like this, follow him on twitter!
