Ariana Grande Vocal Range: (C#3-E7) [live & studio]

Please, MAKE SURE THE ANNOTATIONS ARE TURNED ON! :) ...I couldn't find one, so I decided I would make it by myself. It took a lot & I did everything only by ear. So, if something's wrong, please, let me know & I'll fix it.
I also couldn't find a lot of videos of Ariana singing in her head voice or in whistle register, so, those parts are pretty small. Sorry guys!
