Overtone singing is a voice technique where it seems like one person sings two notes at the same time. The same technique is used by Tuvan (or Mongolian) throat singers and also Tibetan monks have been practising this for centuries but what this woman does with her voice is really fascinating. In this video below, Anna-Maria Hefele demonstrates polyphonic overtone singing in a blow-minding way. Her ability to create two tones simultaneously is almost inhuman. This is really amazing. A must see!
