Nicki 2 octaves, 4 notes

and Nickis chest is capable of hitting the 5th octave.

3 octaves and 2 notes.

Katy has 3 octaves. there was a video of her warming up and talking to her vocal coach and they discussed her full range
the highest note i heard her do live was a D6 from last friday night and E6 during california gurls

Katy Perry has 4.You prolly didn't see her I kissed a girl video live yet.Wiki didn't update her freaking page.

TOPIC: My faves has a lot , she can slay you and still using the note.Either low notes and high notes she has five.

Idk. Gagas needs to be updated tbh

the c7 in her I kissed a girl performance doesn't really count to her range though ,it was more of a pig squeal. Katy's coach said it himself she has 3 octaves in that warm up video from kp3d. but with time i'm sure Katy can extend her range

Allegedly 3 octaves and 3 notes or something like that.

7 on a good day.

minus 6 you were just a little off.

I didn't know you stanned for a keyboard...

Back in the day 5. Now I would say 3-3.5.

Keep it cute, gorl, especially since Rihanna has a wider range than your fave.

I wish I knew Will Young's it seems pretty varient, because He can sing rather high but not sure how low he can go
