My name is Stavros and I am 16 years old. My voice changed around 12-13 and my voice stopped breaking around 14. I've always wanted to sing. My current range is B1-F#5. However, I flip into falsetto around F4-F#4. On a very good day I can hit a chest G4 briefly but most days it will crack. I want to be able to sing songs sung by tenors or high baritones (chest voice going up to B4 and C5). I want to be able to expand my chest voice. Am I stuck like this? Or can I change how I am and make my chest voice register wider so I can do higher belts? BTW I am starting vocal lessons in a week. My lessons will be weekly.
