Watch German vocalist Anne-Maria Hefele demonstrate the technique+ READ ARTICLE
In this video, German vocalist Anne-Maria Hefele demonstrates a technique called ‘Overtone singing’, wherein she simultaneously sings multiple notes at once. 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!
