My Madde simple tutorial. Changing the relation between F1 (the first formant) and F2 (the second) we have different vowels.
In the second part of the clip I change the overtones intensity, so we can listen each overtone frequency.
Digital diapason is not a sinus wave. This is my explanation.
Exercises proposed in the video are part of the method Vocal Harmonics in Motion designed by Lorenzo Pierobon.
Learning to send resonance in the membrane of the drum helps awareness of voice and increases the emission control. The vibration feedback is immediately visible through the colored material that you have on the drum
There are 3 examples. In the first and second we can see the extra-formant in the middle of the screen (~ 2500 Hz - 3000 Hz). Changing the pitch, the position of formants is the same. In the third example I have changed DIGITALLY the pitch, in fact formants change position = the sound seems artificial.
This is a visual-audio mixer software very interesting. It is not mine, I only try to explain it. Each great circle is a sound (obviously you can upload yours mp3). The little balls are pan-pot. Moving circles you can mixing all that you want. Contact me for more explanations. To download: http://visiblearea.com/soundfield/index.html
From Tosca: "Un tal baccano in chiesa!" by the great baryton Leonard Warren. Look at the extra formant to the right.
I have multiplied the frequency of a sinus wave for 1,618 (the magic number) and the result for 1,618 again, and so on. The obtained sound is very strange. I will try with my voice.
