Inspired by Chimier (whose Vocal Prime comparisons this video is modeled after) and WestVoice (who encouraged me to make the video), this is a comparison between The Songbird Supreme, Mariah Carey and Christina Aguilera on live vocals in their respective primes. When making comparisons between two singers, we are to judge those singers at their best so that a fair and objective conclusion can be reached. Who is the best singer between Mariah and Christina in their prime? Listen and decide for yourselves. I hope you enjoy this video. Mariah Carey's vocal prime: 1990-1996 (7 years) Christina Aguilera's vocal prime: 1999-2004 (6 years) Lower Register Eb3, E3, F3, F#3, G3 Mid/Upper Chest Register G#4, A4, Bb4, B4, C5, C#5, D5, Eb5, E5, F5, F#5, G5, G#5 Head Voice/Falsetto E5, F5, F#5, G5, G#5, A5, Bb5, C6 (No B5) Whistle Register E6, F6, F#6, G6, G#6, A6 Notes: A couple of Christina's clips are out of sync and I apologize for that. Also, this is strictly a VOCAL comparison so keep the comments about their vocals. In other words, no bringing up sales, awards, tours, hits, praise from others, or the personal lives of either of these women. Any comments that stray from the topic of the video will not be accepted.
