What do i practice on?

SwanHtet

Hello, everyone. I'm Stephen. My range(chest voice and so called head voice that resonate in the head) is up to D4. Once I go higher My voice becomes instantly lighter and shifts gear into reinforced falsetto or head voice to C5 instantly. I can reach C6 with reinforced falsetto. So, when i want to sing songs in the 4th octave in chest voice. I can't. That area is undeveloped. Do I need to practice mix voice?

Thank you

yes, I would do that, and go back and forth chest and Light chest
