Having practiced this technique for more than 10 years now, Hefele manages to sing a low note and a high-pitched scale at the same time, even moving the notes in opposite directions. The sound she makes is eerie – kinda like the music you hear in sci-fi movies – except this one has no special effects! Prepare to be blown away!
