" music transports me immediately into the condition of soul in which he who wrote the music found himself at that time. I become confounded with his soul, and with him I pass from one condition to another. But why that? I know nothing about it? But he who wrote Beethoven's 'Kreutzer Sonata' knew well why he found himself in a certain condition. "

― Leo Tolstoy , The Kreutzer Sonata and Other Short Stories
