Hello guys. I need your help! My vocal range is F2-A4 in chest voice. My loud and strong head voice starts from D#5. From A4 to D#5 i can't sing loudly. If i push higher on chest voice it's break. If I tried in head voice it's soft and quiet, like falsetto. What i should do, to nicely connect this two registers? Thank you in advance and sorry for my english.
