A bass singer with an exceptionally low range.
- ‘The towering basso profundo brought a magical tenderness to his opening aria, with cleverly timed political quips and his deep bass lent warmth to the lyrical a capella friendship quartet.’
- ‘That turned the tenor of the day into a somewhat confused basso profundo, capable of little more than a hesitant adagio molto.’
- ‘I was a trumpet in Army, and the basso profundo in the other two.’
- ‘And, since my husband won't sing to me, I don't really know that he's a basso profundo, but his voice is rather low.’
- ‘It is hard to believe he was a Basso Profundo from this recording.’
Mid 19th century: Italian, from basso low + profondo deep.
