In the 19th century, the era of romanticism in music, some composers and critics argued that music should and could express ideas, images, emotions, or even a whole literary plot. Challenging Kant's reservations about instrumental music, in 1813 E. T. A. Hoffmann argued that music was fundamentally the art of instrumental composition. Five years later, Arthur Schopenhauer's "The World as Will and Representation" argued that instrumental music is the greatest art, because it is uniquely capable of representing the metaphysical organization of reality. He felt that because music neither represents the phenomenal world, nor makes statements about it, it bypasses both the pictorial and the verbal. He believed that music was much closer to the true nature of all things than any other art form. This idea would explain why, when the appropriate music is set to any scene, action or event is played, it seems to reveal its innermost meaning, appearing to be the most accurate and distinct commentary of it.
