McFerrin, at the end of the video, comments that no matter where he goes in the world, every culture can follow the scale just as well as the audience in the video: I'm not so convinced it is instinctive or embedded in us in some way as he seems to imply. If you watch closely at the beginning of the video, you will see that McFerrin doesn't give the audience just one note to repeat (and the audience intuitively follows), but he gives a second note as well. This suggests to me that he set up a pattern any human capable of seeing a pattern could get, and had he chose the Chromatic scale or some other scale and demonstrated the first two notes, the audience would be able to follow that scale as well -- that is to say there is nothing special about the Pentatonic scale as shown in this demonstration. As an analogy, if I count 1, 2, 3, ..., and ask you for the next number, you would intuitively say 4 and continue counting in that fashion if I asked you to do so -- but the same could be done for the even numbers, odd numbers, prime numbers, etc. The choice of the natural numbers as my analogous 'scale' is as arbitrary for my math sequence as for musical scales. This is not to say cultural and other factors don't influence us into thinking the Pentatonic scale is somehow 'special'. One has only to look at the arbitrary number of degrees in a circle to see that this is so -- but I'm only arguing against this specific demonstration as evidence of that there is something special about the Pentatonic scale when I have a plausible alternative explanation for why the audience followed the pattern. In any case it is a neat demonstration (one, to the consternation of my other house guests, I participated in with the video audience). What do you think? Am I right? Wrong? The sexiest man alive?
