The jazz vocalÂist and ten-time GramÂmy winÂner BobÂby McFerÂrin turns 61 today. To celÂeÂbrate, we’re postÂing this clip from the 2009 World SciÂence FesÂtiÂval, in which McFerÂrin leads an imprompÂtu audiÂence sing-a-long in order to demonÂstrate the powÂer of the penÂtaÂtonÂic scale. We bet you’ve nevÂer seen music theÂoÂry taught quite like this.
McFerÂrin, by the way, is sharÂing the stage with sevÂerÂal sciÂenÂtists, includÂing Daniel LevÂitin, McGill proÂfesÂsor and author of the book This is Your Brain on Music. If this clip hapÂpens to awakÂen your inner croonÂer instead of your inner neuÂroÂsciÂenÂtist, you can also check out a short singing lesÂson with McFerÂrin on Qtv.
