Singing two controlled vocalized notes at the same time! German singer Anna-Maria Hefele stunned the world with a viral video showcasing polyphonic overtone singing, a vocal technique that lets her sing two notes at once. By skillfully shaping her mouth, tongue, and throat, she amplifies harmonics above a base pitch, producing clear, flute-like tones. Trained at the Mozarteum University in Salzburg, Hefele has since performed worldwide, blending art, science, and education. Her unique voice has been studied through MRI imaging and praised for its precision and beauty. Through concerts, workshops, and research, she continues to expand the boundaries of what the human voice can do.
