Vocal Type: Full-Lyric Soprano
Vocal Range: C#3 - Bb5 - EB7 (4 octaves one note)
Vocal Strengths: In possession of a strong, dark, raspy and mid-weighted soprano voice, Demi Lovato is known for her powerful instrument that is piercing in tone and able enough to cut through thick instrumentation [Remember December].
Demi, unlike most "entertainers" of today, relies heavily on her voice to convey the drama and emotion of a song. It's perhaps because of this, she continues to develop and train her instrument. The gains are most noticeable during performances where it has helped to remedy previous live vocal inconsistencies. Alongside this training, Lovato has also improved her musicality, creating a unique, contemporary-oriented style of harmonising that works with her voice and melodies [Lightweight].
The lower register lacks vocal tone and resonance below F#3 and stops projecting below Bb3, however the Diva has been able to sound strong, comfortable and effortless even at the bottom of her range [Neon Lights]. This is, in part, due to the afore mentioned development in vocal technique. Thought the lower range does lack the audibility and strength the voice is known for, it does display a dark, warm timbre [Give Your Heart A Break].
Lovato's mid-range can be manipulated from a light, feminine timbre that showcases Lovato's true soprano voice [Cool For The Summer], to one that is brighter, fuller and more cutting in tone [Never Been Hurt]. Improvements have been seen, with the Diva now being able to make more easy use of melisma in this part of her range [Give Your Heart A Break live]. However, the most common use of Demi's mid-range is as a step into the upper chest or down into the lower extremities without having to break the vocal line or take a breath [Here We Go Again].
As the Diva ascends into the belting range, she gains her signature brightness. With excellent breath control, she is able to sustain notes for extended amounts of time- most usually with her trademark smooth, rolling vibrato applied [Quiet]. There is a duality to this part of the range, with the Diva able to sound free, effortless, bright and resonant [La La Land]- when favouring a head dominate mix- or tight, throaty and pulled [Skyscraper]- if the balance is weighted in favour of the chest. In addition to this ability to manipulate the belting range's tone and texture, Lovato has incredible vocal endurance, able to fire top notes back-to-back [Aftershock] with resonance and phenomenal usage of vibrato [Stay live]. These upper belts can also be sustained for extended amounts of time [Fire Starter].
The head voice has been slowly developed over time [My Love Is Like A Star], becoming full and controlled. Despite its under usage, the voice exhibits freedom and a comfortable, bright nature at its top [You're My Only Shorty].
As a whole, Demi is a good example of how training can lead to improvements in ones voice. From being a poor technician with little musicality, she has grown to become a strong vocalist with musicality (shown in her unique way of harmonising) and incredible versatility. With this growth, Lovato can now change the weight and texture within her voice at any given moment: being light, soft and emotive [Nightingale] at one moment; and dark, full and with more weight [Mistake] the next. It has also afforded her better mastery of dynamics, being able to be to play with the voice's volume without issue.
Vocal Weaknesses: When singing live, the Diva previously tended to favour a high laryngeal position with her upper belts. But over time, this has improved, and the Diva sings with a much better vocal technique. However she is inconsistent when applying this healthier technique.
