What was Barbra Streisand's vocal range?

Answer 1

Björk's vocal range covers three octaves, from F3 to E6. Taking into account this and her timbre, we conclude she is a soprano (her vocal coach said she was a robusto soprano, which means she has a lot of fullness of sound in each note).

As pop singer, Björk uses her chest voice more often and tends to produce high notes until C6 with this one. In Play Dead, Pneumonia, Human Behaviour, Headphones or Vertebrae by Vertebrae, we can hear her high chest notes that go til C6. In Sun in my Mouth, Anchor Song (live), Bath, Storm... we hear her head high notes, which have that same fullness of chest notes, which is quite unusual.
