Rhydian, you are a baritone and this is where your strength is. Sure, your range is marvelous, but you are not a tenor. Stick to the baritone range only occasionally venturing into the tenors. Classical tenor arias are not for you, Although I love your voice. I tried to become a heroic tenor myself, but had to give it up. It can work, but it does not work for you. Your best notes are around the middle C and even deeper. Then you sound like a man. Stick to the classical baritone repertoire going higher in crossover songs. You are one of the best voices of our time. Do not damage it with notes did are far too high for your lovely natural baritone!
