Italian voice expert Rodolfo Celletti said of Adelina Patti:
Her voice was a technical marvel. The staccatos were marvels of accuracy, even in the trickiest intervals, her legato was impressively smooth and pure; she connects the voice from note to note, phrase to phrase, lifting and gliding with an exceptional virtuosity. Her chromatic scale was deliciously sweet, and her trill was wonderful and solid.
