The frog twang and the chicken twang

[funkypou]

Hi everybody,

As my first post, I would like to share a video that helped me finding a comfortable twang :

When trying to find the twang, I think I was doing what Kimberley calls "the frog twang", which made me feel a resonance low in the back of my throat. Though I could feel the "buzz", this wasn't very comfortable, especially when trying to apply distinct twang.
Now that I have directed the resonance toward my nose, it feels easier and I think I have less unwanted distortions. Could this be related to what some people call "singing into the mask" ?

I would be glad if this video could help somebody and would appreciate any comment, explanation or criticism.
