I’m a male and I’m 17 (it is relevant but not really) and I was singing in the fifth octave, I can hit about an F#5 but after that I have to really try to hit the notes. At one point I thought I wonder how high I can go so I just started ascending until my notes were basically inaudible at G5. Until out of nowhere I hit a C6. Then later I managed to go up to G6. What the heck happened. Should I try to go lower/higher? Or this just a freak anomaly?
