Frankly, not enough can be said about Carey’s voice or the emotional goosebumps she puts behind it. Whether she’s shrilling high up into the rafters or anchoring a song with her velvety lower register, her ability to transform her five octave wonder from just a voice to a musical instrument is brilliant. Take a listen to all five of Carey’s octaves complied from over twenty years worth of self-penned music and edited into a one-minute [fanmade] video after the jump!

4 octaves - the maximum range of voices of singers, which is very rare.
Mariah has quite possibly four octaves.
Talk about 5 octaves - is a myth!
Freddie Mercury, for example, 3.5 octaves, he is a genius singer!!
