The well-known Freudian psycho-analyst and digressive interpreter here uses the hitherto unexplored role of music in the subconscious as a theme for variation. Many of the ideas here are original, and once again Reik turns to himself for the greater part of his material. In the first section of the book, Reik uses as illustration the spontaneous musical associations which have frequently given him the answer to a puzzling psychological problem in a patient. The second, and most interesting part of his book, concerns the melody which has haunted him for the last 25 years and which reveals his own identification with Freud.... Reik himself is a Viennese, steeped in the musical culture of that city, and music is apparently a second, or at least a second-nature language to him. But it seems questionable whether music would thus furnish a key to analysts of another background..... The market is a special one, and you can determine yours by the demand for his previous books.
