OK, I believe I'm the first one asking this question because I tried to find answer everywhere and just couldn't!
I am 15 years old (almost 16 years old). I always knew how to sing, and two years ago, I joined a choir in my city. After they checked my range they put me as a "young tenor".
Time has passed, and I really don't know if my voice has changed yet, but now I have something really confusing. Right now, this is the situation: my chest voice sounds really low and dark, like a low bass, and that worries me because I want to stay a tenor, as my chest voice can go down to E2 at its lowest and up to E4 maximum.
The weird thing is, my head voice, which I'm not so sure is a head voice and not a chest voice, can go down to to F2 with much diffuculty and maximum up to F6 with falsetto, but regularly my head voice is like a natural lyric tenor, just like Bruno Mars, and when I speak, I don't know which voice I should use, the really low one, which some can say might be my chest voice, or the one I regularly use which is my lyric tenor voice.
