In reply to Vocal bible.

All Brandy has over Beyoncé is tone and creativity both being subjective factors. Range, power, pitch accuracy, register transitions, volume control, speed and precision of runs (Brandys got her on artistry in that area) and vibrato Beyonce is the considerably more technically accomplished vocalist.

Brandy is the Vocal Bible for her artistry/musicianship when it comes to use of voice. She provides a guide for singing with accepted rnb/gospel nuance and characteristic.

What is NOT a reference to is technical singing ability
