A few tips I would like to share:

1. Always be sitting up, no laying down. Why? because it is harder for the air to flow.

2. Relax. If you can step back and see yourself singing you will realize that it's easier to drift into your music when you aren't worried.

3. Tap. If you tap to beat it's easier to remember what word comes next cause alot of songs say stuff on the beat.

4. Project. Even if it is scary, you sing and sound better if you are loud. You and your audience can hear you.

5. Memorize. Memorize the beat and the words. When memorizing memorize what you say with the beat.
