I have been really frustrated for the characteristics of my voice. I have a very light, metallic timbre in it that gets a little warm the higher I sing, but I cannot reach even a Eb4 without straining A LOT.
While the lower register is there (it's consistent) when I get lower than A2 I lose all the resonance and it becomes very airy and weak. After doing research and reading a lot I conclude that for the color and weight of my voice I must be some kind of tenor, but the passagio (I know there is two of them) does not fit with the extremes of my range.
I have never heard of a tenor that strains in Eb4 like I do, it is just impossible to me sing that without strain and change to head. I personally think that it may be the strain in my neck that does not let me go higher, because all muscles just get harder and it feels so uncomfortable.
I was in a choir in November/December last year, and the teacher seems to be so confused about me like I did (and still do). After checking my range and make me sing scales he says: "Yes, you are a tenor". And then he press the E4 key and make sing it, it sounded horrible obviously, and he says: "You should be able to sing there"... But I can't. He never answered my questions, and I was worried about making him get angry.
