I'm an orchestra and choir opera conductor, but I prefer to analyze vocal formants, sonogram and spectrogram. My workshops are instructions about formantic analysis of overtone singing and opera singing by audio software. I work for disabled children in public secondary school since 1997.
For my compositions I use my voice and my vocal samples (sometimes some whale and dolphin samples).
Sometimes I think that my music is no natural, because I also use my voice digitally processed by software. Ok, I use time streching, reverbs and many filters only.
But I love work with my overtones and process them.
