They are indeed!
I was clearing some junk today out of the old suitcase because I need another one for my vacation and there was this flute (if that's a correct name). I almost forgot about it...
I love flutes...have a kind of little collection from different countries at home.
I was searching: would you know, by hazard, the name of this kind of flute, but with a deeper sound, which is playing at the beginning of "Stars"?
I really love the sound of this instrument.
