Help singing???????????

You must sing through your nostrils and mouth, or your notes won't sound right. Here's what I do. Hold out a note, plug your nose, then release. Repeat so you can hear the difference. Or hum, and plug your nose, you'll know you can't hum when your nose is plugged. That's why your nostrils help your singing sound beautiful in its own way. If you're (not) in choir, try out for it or anything else that has to do with singing and using your vocal cords, like cheerleading, musicals, plays, and many more. Sorry this is so long, but if you really want to sing, you need to know the basics to start with "the voice". Just believe in yourself. :)
