How Not to Embarrass Yourself at Karaoke
Warm up all day. Start by counting aloud when you wake. Later, laugh out loud; we laugh higher than we talk, so you'll be activating your upper register.
Lubricate your voice, especially if you're nervous (stress can dry out your vocal cords). Half an hour before you sing, eat a little bread soaked in olive oil.
Breathe from your diaphragm. You'll generate the air you need to produce a melodious tone. Inhale through your nose and push your belly button out. Exhale and let your navel go back in.
Feel free to change keys. Even the pros sing in a lower register when their voice gets tired.
Sing with joy, from your heart, and no one will care how you sound.
