Tamar Braxton 

U R retarded!!How can youtube not be a verifiable source. I put a clip of her hitting a D and E one octave above Soprano C(D7 and E7) and you say it's not a good source? What is then! I bet if I even got a video of her hitting whistle notes you'd say it wasn't verifiable. Of course it it. if you see or hear her hitting a whistle note, then she's a whistle registre singer. The same applies to all whsitle register singers!!!! U R just stupid!!!!! U and Mr. "I'll bring the food" who totally destroyed the Whsitle register singers category.
