She wrote brilliant operettas in collaboration with Tourguenief, but they were never published and were performed only in private. One anecdote will show her versatility as a composer. She was a friend of Chopin and Liszt and her tastes were strongly futuristic. M. Viardot, on the contrary, was a reactionary in Mp3 Music. He even found Beethoven too advanced. One day they had a guest who was also a reactionary. Madame Viardot sang to them a wonderful work with recitative, aria and final allegro, which they praised to the skies. She had written it expressly for the occasion. I have read this work and even the cleverest would have been deceived.
