Ongoing Issue, Losing Notes in Head Voice
Hoping to get some advice on a frustrating issue. I have an appointment with a voice institute next month, but maybe there's something I can do on my own. It started two years ago when I was trying a song that I wasn't ready for (My Kinda Lover by Billy Squier), and kept trying to hit the A4 in full chest voice. Not resting enough in between, and I guess I was beating up my cords in the process. I didn't feel any strain or pain or hoarseness though, no warning signs. But after a few nights I noticed that I could not phonate from about a G4 to a C5, especially in head voice. And it took a few weeks of no singing before I got it back. Well since then I have worked a lot, have added a couple notes to my chest voice, and can pretty seamlessly connect all the way through to E5 in full/mixed voice. I don't sing forcefully, I have good support, and never feel any fatigue or tension or pain in the throat or neck. I have a lot of ping to my voice. I probably do use too much air though. Anyway what happens now is that after I sing for less than a half hour where some notes are in the range A4 to C5, I start to lose my head voice. It starts out gradually, breaking up here and there (especially after a consonant), then it gets to where I can't sing those notes at all in head. I can still sing the A4 and B4 in chest voice, but in head it sounds weak or flips up to some higher note... like I have no control or flexibility. And I can't blend chest with head like I normally can. I don't have mucus to speak of, I eat only a slice of cheese a day and no other dairy, and always hydrate a lot. Sorry for the book, but I'm really hoping to get some insights on what I can do about this.. as it's very frustrating to have put in so much work and made a lot of progress, but be held back by this issue. Thanks in advance for any help!
