what type of music do you plan on singing. there is a big difference in screamo hardcore bands and the church choir
all singing tho takes good suported breathing. think of your ovaries (if you have any) as lungs and breathe deep filling them up with air. or thats how i think of it
also don't use your throat- ever- its a really ugly sound you'll make. and don't go Nasal- EW- thats my total pet peeve.....
