Very Vocal Pedagogy nerd question

Hello Camille,

I have a problem understanding harmonics and formants.

I know the first formant is about the registers where if you have a chest sound we get a high formant and in head voice/falsetto we have a low formant. I also know the second formant is about brightness and darkness where if you have a bright sound we have a high formant and when the sound is dark, we have a low formant.

Now harmonics in my definition are the notes we are singing to get the "actual" note we are singing.

So the part I'm confused about is what takes place in the video Freddie Mercury Vocal Analysis - Ep. 5 Voice Lessons Online. So from and starting from 5:58 Zac Bradford is talking about the use of formants and harmonics to get the resonance for belting. At around 7:28, Zac talks about the third harmonic being the most prominent in the sound specturm. He goes on to make an educated guess that the second formant is giving rise to the third harmonic. Now, in the next example he uses the same process and says that the first formant is giving rise to the second harmonics. Now I get harmonics by themselves and formants by themselves, but how do they relate to each other?

Thanks in advanced Camille and have a wonderful day!

Here's a great explainer on formants and harmonics: https://www.voicescienceworks.org/harmonics-vs-formants.html. The site also has further recommended reading!

I also recommend checking out the work of Ken Bozeman - here's an interview with him on Dr. Dan's channel: https://www.youtube.com/watch?v=9qBTbDXRyik. 

Thanks Camille! I think I'm getting a better understanding of this concept. I have another question though. I saw from a Dr. Dan video that there is actually six formants, but the first two foramants are the called "vowel formants". What do the other formants do?

Most teachers and voice scientists only talk about 2 formants (F1 being the throat, F2 being the mouth). But it's possible he's referring to harmonics? I'm not sure, Aaron!
