Sophia Giustina Dussek (née Corri; later Moralt; 1 May 1775 in Edinburgh – c. 1831 in London)[1] was a Scottish singer, pianist, harpist, and composer of Italian descent.
She was a soloist in the London premiere of the Requiem, given at John Ashley's Lenten Oratorios, Covent Garden, on 20 February 1801.
In an account of uncertain veracity, it was reported that Sophia, who had fallen in love with another man, asked Dussek for money to repair her harp.
She then used the money to leave the house, removing her belongings in her harp case, and claiming to have left for dinner with a female friend.
After Jan Ladislav's death in 1812 Sophia married the viola player John Alvis Moralt.
