Hello from New Mexico. This is both an introduction and a question...Have been singing, playing music my whole life but don't feel completely comfortable- 'not good enough'. A vocal coach awhile back said I need to get over that, and in passing told me about KTVA. Finally decided to try it. So far, I have a better grasp of what breath support really feels like. I have often been encouraged to open my mouth, my jaw wider. And I can't. Because of worsening jaw pain over the years I finally checked it out, and xrays show I had an old injury, possible a broken jaw and ruptured tmj disc After several specialists and a second/third opinion, it appears that the only remedy is jaw joint replacement surgery, since mine has degenerated from what they call severe reactive arthritis.. Many hoops to jump through and any surgery, if I decide to proceed, will be over a year from now. Problem is, I've lost motivation to sing. Confidence comes and goes. I wonder what's the use if I can't open my mouth wide like really great singers. I suspect that helps, but that it's most important to have good strong breath support. The opening at my throat is also smaller than normal, I have learned since recent eval for sleep apnea. I have learned that sleep apnea can result from jaw displacement. People like my voice, but I don't always 'own it' with a song. I suspect that with good instruction and breath support, I can still sing out stronger. Are there any great singers that don't open their mouth/jaw wide?
