I'm not a singer but trained flutist, 22 year old male. I compose melodies but I find struggling to vocalise them. I recently found my vocal range is from B2 to D4, E4 before it breaks. I was disappointed to have a very small vocal range, feels like I'm less "human", its psychological may be.
Although I don't intend to sing brightly, I would like to be able vocalise the tunes I make. Is it possible to improve my vocal range at this age?
