Vocal Type: Soprano
Vocal Range: 2 Octaves 2 notes and a1 semitone F#3-Bb5 (Note: she has claimed to have had a 4 octave range. If anyone knows any lower, or higher notes she has sung, please get in contact or comment.)
Whistle Register: No
Vocal Pluses: Classically trained, powerful yet dexterous soprano, with a gorgeous clarity to her tone and a natural vibrato. Seamless transition between registers. Vocal stamina in her youth - she was on Broadway constantly from the age of 20 - 23. Wonderfully expressive phrasing and emotive interpretation of song. Also a superb actor (Oscar-winning) and dancer.
Vocal Negatives: Due to her reliance on classical technique, she struggles with certain styles (ie her 'Jazz Hot Baby' from 'Victor Victoria' isn't really that jazzy or bluesy!). However superb at musicals, operetta and light classical music.
Thanks To Karen V for directing me to the notes, and providing the positives and negatives.
2 Octave Vocal slide: G3 to G5 (Illustrates her ability to navigate the different parts of her voice with ease.)
Finally, Julie Andrews offers some sage advice to any aspiring singers out there:
