I've been trying to learn singing for sometime now and have gone through dozens of videos and articles understanding voice/vocal folds/registers/bridging/exercises-lip-trills-apreggios..etc,. since I'm a lil science driven. Just too much information though, all that. I've also been going to a vocal instructor. There is one thing that I never understood and at the same time feels like would be the key to my primary problem with singing.
So, let's say I'm singing a song and I get to a high chorus with relatively high notes, I start struggling a bit(not too much, but you know some kind of tension) like I'm near the roof of my vocal range(like 'Ugghh!'). Am I supposed to bridge into my mixed voice here?
I can bridge my vocal-registers pretty ok when I'm doing lip-trills or some exercise, but when it comes to implementing it in an actual song, it's very un-natural for me and is almost confusing. And it's damn tough! I either end up with wrong notes, nasal-tone or slip into falsetto totally. Could someone help me out with this? Can this be mastered? What exercises should I be doing? As a beginner, how do I know I'm employing the right techniques to my singing?
