I am a natural baritone (I think). My lowest note is C3 and highest G5-B5. Am I correct that I am a baritone? My voice is VERY deep, and I cannot hold a note as high as a tenor. Just to give you an idea, I have the same timbre as Gianluca from the group Il Volo. And I am having a problem when I sing, that is, that too much mucus gets stuck on my throat (I know it's gross) and when I aim for a note it comes all rough. Help please?
