The idea that Tchaikovsky anticipated the experimentalism of the Symbolists and Surrealists runs counter to his conservatism as a person and as an artist, his reverence for the music of eighteenth-century composers, reliance on the number format in his operas, general adherence to the diatonic system, and predilection for German augmented sixth chords. But he embraced these things in order to counter them, or to highlight and enhance them with his own unmistakable signature. – Times Literary Supplement
