Octave Span: ≈ 2.5 octaves
Primary Voice Type: Contralto

Is Gladys Knight a Contralto? Understanding Her True Voice Type
Gladys Knight is widely recognized as a true contralto, one of the rarest female voice types.
A contralto is defined by:
- A naturally lower tessitura
- A dark, rich vocal timbre
- Strong chest dominance
- Comfortable phrasing in notes that mezzo-sopranos or sopranos approach with difficulty
Why Gladys Knight is Classified as a Contralto
- Deep Natural Tone: She consistently sings in a lower register with clarity and vibrancy.
- Chest Voice Strength: Knight carries chest resonance higher than many female singers, a classic contralto trait.
- Lower Tessitura: Her melodic lines sit comfortably between A3 and E5, the typical contralto range.
- Distinctive Warmth: The “smoky,” soulful quality in her mid and low register is uncommon among mezzos or sopranos.
Although early in her career she demonstrated mezzo-like agility, her core identity remains contralto.
