Lea Michele (Rachel from Glee) - Vocal Profile/ Range

Lea Michele

Vocal Type:Soprano

Vocal Range:2 Octaves 1 notes and a semitone F#3-A5

Vocal Pluses:Technical singer with a good grasp of her voice as a whole, thus the sound it produces is always supported well. Her chest voice is crystal clear and has great dynamics, with the higher belted notes being reached through the aid of mixing with the head voice. Her intonation and delivery is also brilliant meaning her voice can effectively communicate a song's emotion and sentiment without sacrificing the audibility of the lyrics.

Vocal Negatives:Her vocal styling means that the vast majority of her performances have a theatrical feel to them, suggesting a limitation to the genres she can sing. Also her chest register can sometimes sound overbearingly strong/piercing, especially when the notes aren't softened with vibrato.

[Vocal Profile] Sade

Sade

Vocal Type: Contralto
Vocal Range: 2 Octaves 3 notes D3-G#5
Vocal Pluses: A voice that is texturally united throughout the range. Warm and smooth, Sade’s strength comes from her tone and timbre [Lovers Rock]; skill emoting [Smooth Operator]; her musicality (e.g.building harmonies) [Slave Song]; and ability to alter dynamics [King of Sorrow]. This puts her in contrast to other “powerhouse” Divas who use more obvious skills- such as melisma and high octave belting- to impress, but it makes her no less a vocalist. Her voice has a “quiet storm” beauty.

As mentioned above, the Diva has excellent volume control and breath support, which she uses to create the requisite mood and ambience to compliment the production. Though often found to be singing with a low/medium volume- something which is often (wrongly) credited as the reason for the soothing quality of the voice- she can shift dynamics without any negative effect on the timbre of the voice [Pearls].

[ Vocal Profile] Lady GaGa

Lady GaGa

Vocal Type: Mezzo-Soprano
Whistle Register: No
Vocal Range: 2.7 octaves (C3-B5 approx)
Vocal Pluses: Powerful, passionate,  multifaceted voice. Not only is it an expressive and well controlled instrument, but it's one that doesn't weigh on melisma to impress (though she is capable of using this vocal technique if required [Do What U Want] ). With her excellent breath control and knowledge, the Diva can hold notes [Fashion], jump octaves [Venus], and play with vocal dynamics at will [Bewitched, Bothered And Bewildered].

Lady Gaga's low notes are well supported, and have a dark, solid and medium weight to them [Scheiße]. The mid-range is as chameleonesque as Gaga herself. It can be controlled, measured and mature [Fashion]; theatrical, poised and smooth [Lady Is A Tramp]; guttural, raw and raspy [ Dope]; or made perfect for pop music with the character stripped back, and a light, bright quality used  [Poker Face]. All this vocal variety stems from Gaga's excellent understanding of placement and technique.

Alexandra Burke - Vocal Profile/ Range

Alexandra Burke

Vocal Type:  Contralto
Vocal Range: 2.3 and a semitone octaves. E3- Bb5 (approx)
Longest Note:10 seconds - 'The Silence'
Vocal Pluses: Rich, deep, silky texture that permeates the low to midrange. Her chest voice impressively retains a weight even up into the fifth octave and has a raspy quality that adds an interesting texture to the voice. She is able to hold notes easily, with or without applying her quick vibrato.
Vocal Negatives: Her head voice is relatively weak and poorly connected to the rest of the voice.
