As expected, the Brown Eyed Girls are turning heads everywhere with their concept, choreography, and sound from their "Sixth Sense" comeback.  In particular, their three-part high note near the end of the song has been earning explosive attention, leaving many fans impressed with the ladies' potential. The group recently completed their week of comebacks and sang high notes estimated to be over five and a half levels effortlessly on stage.  It's a note that's difficult for anyone without training to accomplish and is often compared to the high pitched sound dolphins make. One of the most popular stars known for their high notes is Mariah Carey and her song, "Emotions".  As for the Brown Eyed Girls, all three vocalists connect their high notes in the order of Jea, Ga-In, and Narsha.  When the song was first released, many wondered whether the girls would be able to pull it off live, but the girls proved that they could and so much more.
