While in London, Chopin frequently gave performances at soirées and matinées where he performed Nocturnes, Waltzes, Mazurkas and the Berceuse George Hogarth reported in the Daily News (10 July 1848):
He accomplishes enormous difficulties, but so quietly, so smoothly and with such constant delicacy and refinement that the listener is not sensible of their real magnitude. It is the exquisite delicacy, with the liquid mellowness of his tone, and the pearly roundness of his passages of rapid articulation which are the peculiar features of his execution, while his music is characterized by freedom of thought, varied expression and a kind of romantic melancholy which seems the natural mood of the artist’s mind.
