Getty. Few singers can match Mariah Carey's mind-blowing ability to sing a reputed five octaves -- compared to a piano's seven -- and now the veteran pop diva's vocals have been put to the test. Well, sort of: a cleverly spliced YouTube video shows off the singer scaling, in ascending order, the entirety of five octaves. That's over 65 keys, for those who can do the math, or just make it through the ear-splitting, tea-kettle high notes at the video's end.
The name Isabelle is of French origin. The meaning of Isabelle is G-d oath, pledged to G-d. Isabelle is generally used as a girl's name. It consists of 8 letters and 3 syllables and is pronounced I-sa-belle.
The variant form originated through the loss of the first syllable and the replacement of final /t/ with /l/ (as /t/ does not appear word-finally in standard Spanish). Both forms of the name exist concurrently in Italian (Isabella and Elisabetta) and French (Isabelle and Ãlisabeth). Both names have been borrowed into multiple other languages, giving rise to various local forms.
