I tested my vocal range today. My voice is well enough to be accurate today. I was able to hit an A2 (without any vocal fry or that bumpy, not-very-solid low note sound) and peaked at a G5. My G5 was definitely head voice. Will I ever be able to bring chest voice that high? How can I expand? I'd like to go both lower and high. My goals are to expand my range from an F1 to a Bb6. Is that an unreasonable goal? Also another goal I have is to be able to sing for like, idk 4 hours. Is that unreasonable?
