Why can't I do head voice
Hello! I've got a question for you! My tessitura is from Bb2 to C#5, my chest voice is from Bb2 to C4; mixed voice is from C#4 to C5. If I push more, I'll sound break a little bit then it ends. My voice continues to go up to C7 with Whistle Register but from C#5 to B5, I can still feel my throat vibrating, I don't understand why? Was I still in mixed- voice from C#5- B5? I thought it supposed to be head voice in that range? Don't I have head voice? And if I push my voice into the 6th octave, my throat stops vibrating and I enter the Whistle Registration. Could you explain it why I can't do head voice? I really appreciated your time! Thank you!
