Longest Note: 21 Seconds
Vocal Type: Light Lyric Soprano (3 octaves, 1 note and semi-tone)
Vocal Rating: B-
Recommended Listenings: Alice, What The Hell, Tik Tok (Cover)
Positives:
A spunky, rock orientated voice. The piercing quality of the voice allows for her to slice her way through the thick instrumentation she often employs, and gives the voice more resonance. She demonstrates ease when hitting lower notes down to D3.
Negatives:
Though resonant due to the piercing quality, the belts are naturally thin, and can sound like shouting. The voice is also nasal at most times.
The Bb2 is not her but the C#3 is. C#3-C#7
In her album "Rock N' Roll," she sang a harmonized G5.
Here's her longest note, starts at 0:30 and goes through F#5, Eb5 and B4.
