Music: Human Formant Synthesizer

Overtone Singing by Anna-Maria Hefele.

Overtone singing is known from the Mongols.

Anna-Maria Hefele combines it with Western classical music.

Explains the concept:

Sings Mozart – in an MRI scanner. She cut her hair for the experiment. She is not ill.

Recording was done in Freiburg. university website

What she does is , while singing, she shapes a resonant band pass filter with her tongue that amplifies a part of the overtone spectrum of her voice.

Male mongol singers use a guttural deep voice, leading to a very dense spectrum of harmonics, allowing them to have many more possible frequencies to amplify than there are notes on a piano.

Here she shows the spectrum.
