I'd like to know what's the main, salient instrument that plays the intro in this video, from 00:04 to 00:17. (Please note that the visuals is, I think, misleading: the players shown are not the ones who play the instrument in question).
I can't figure if it's a flute, an oboe, a clarinet (and if it's one of these, what type of it), or maybe something else.
