Hello can u please do a tutorial or live session on how to do a whistle note Like Mariah Carey or Ariana Grande and/or a raspy kind of singing like Grace Vanderwaal.

Thank you for the suggestion, Hosanna! I cover vocal fry (that raspy sound) in this pop tutorial: https://www.30daysinger.com/tutorial/how-to-sing-like-a-pop-star/1. 

Thank u Camille! but I do not think she is using vocal fry here is the link to her agt audition

Got it! I think what you're hearing is a combination of some vocal fry, some glottal onset, and lots of "pop flip" or "falsetto flip". That would be good to cover in an upcoming lesson! 

Ok thank u Camille
