fedex - 2016-08-03 how is he doing the harmony with himself at the end?
Old_Zircon - 2016-08-04 I'm not a wind player so I don't know exactly how it's done, but the singer in my band in high school was also a flutist and he could do that. It has to do with singing a note at the same time and creating combination tones I think. According to him it's possible to get more than two notes at once if you're a real virtuoso at it.
