In reply to Stripped Voice.

Add 2 c-sections & possible belly lipo and a female singer loses 1 or 2 octaves from her upper register. Same thing happened to Mariah & Céline; hence the former's reliance on head'n whistle and the latter on super head. Keke Wyatt popped 8 kids the natural route and look how connected her voice is, decent bottom to soaring top. Tamar's top's intact, too.
