Two notes, one voice

Anna-Maria Hefele

Voice Artist


No technical glitch, no audio system failure: what you’re about to hear in this extraordinary talk is totally real, and totally human. It is a technique we can all be trained for, and our speaker Anna-Maria Hefele is one of its most prominent representative. It’s called “Polyphonic overtone singing” and it consists in singing two notes in a single vocal emission. Looks like magic, but it’s science-backed hard work and research. Enjoy!
