Gradually lose my upper range
I would like to tell you a sad story about how I gradually lose my upper range. I have no idea what's going on and what to do next.
I was able to power up my head voice. I could mix my head voice(C5-A5) with arbitrary among of chesty sound as I wish(I was born with it). However I could never sing on passagio(G#4-B4). Through my entire singing career I am always seeking a way to sing across the bridge. About one year ago, I started to use some unnatural way to sing and do exercises(I thought it was correct). What I did is I forced my soft palette stable when sing across the bridge. One day I found my head voice get harder to reach and there's no support, but it's too late. I am not able to reverse the muscle memory. I am frustrated because I've sing for ten years but lost my voice in only one year and even speaking voice is affected. As I try to do more exercises things get even worse. Although now I can occasionally do what I could do but in most cases I struggles and sometime a bit painful. Is there anybody ever encounter this situation? Is it muscle tension dysphonia?
