Voice Strain and Head Voice sounds airy

My pleasure, Teodora! Another thing to keep in mind: it's okay (and sometimes necessary) for your body to feel some pressure - we just don't want your throat to feel that. Healthy, strong singing may require us to "lean into" our low body support at times so that our vocal folds and throat muscles don't try to take over and force power from there. 

Dear Camille, it works!!!

I retrained my mind and body to remove the strain from the throat and my voice is recovered now. I do all your warmup exercises daily, but most importantly, I focused on correct breathing. I finally taught my abdomen to maintain expansion while exhaling, that's something I didn't pay attention to before, so I'd run out of breath quickly and place the tension on my throat.

After your exercises I feel that my cords are more elastic and can slide into head voice more easily, it all sounds fuller and everthing is much easier to sing. I have to say that I found those exact or similar exercises online before, but I haven't done them properly because there was no guidance, gradual build-up and a detailed run-through that you provided in your course, so thank you sooo much!

I'll keep you updated and tell you if I want some extra individual training when I do some more advanced things. I am patient but also excited about hearing how I'll sound like in a few weeks. :)

So glad to hear that! I know that it's difficult to change old habits, and it certainly takes patience to see growth, but it's very reassuring when you do. Keep up the great work!
