A little background: I'm a countertenor that sang faithfully since 1996 with my former church in the choir and as a soloist. I've also done some musical theatre. After we did a recording at church in 2007, I stepped away from music because the project never got released and after all of the hard work, I was frustrated and disappointed. I haven't seriously sung since then.
The confidence I once had in my voice that "could do anything" is gone. I'm a year round allergy sufferer (Thanks Indiana!) and recently started going to vocal lessons to get my voice back as I've recently begun transitioning to musical theatre. I'm not willing to go for a lead role until my voice is back to what it once was.
The one issue my vocal coach has found is I've developed glottal/vocal fry in my chest and lower register (it almost always sounds like I need to clear my throat when I get lower or in full chest voice). I can't take ibuprofen to ease the inflammation; VERY allergic. I've been doing tea and honey religiously along with throat lozenges and Throat Coat and even the exercises he has me doing.
The fry is still there. While I know it won't disappear over night, what, if anything, can I do to smooth this fry out of my voice and give me my true tone and everything back? Any exercises or practicing I can do that you would recommend? I'm open to anything now that I'm back to singing!
