I wanted to test my vocal range, and test how high I can go without forcing too much and without using falsetto. I tried to sing C4 to C5-D5 (I did 3 recordings), but I have the feeling that above B4 I'm forced to sing in falsetto (the last note which is D5 is definitely falsetto).
Can you tell me how high I can go without switching into falsetto?
Here are the 3 recordings :
