This paper discusses the status of music in the third critique of Immanuel Kant and the book On the Beautiful in Music of Eduard Hanslick. The Critique of Judgment comes from the impossibility of a beautiful musical based on the concepts of shape, reflection, beautiful as a symbol of the morally good and the relation between music and affection. However, Hanslick gives the music the status of fine art to disassociate the subjective affective content of material used for the musical work itself, for him, sounds in movement. To achieve this objective, the author uses the concept of fantasy as a contemplation with intellect prior to any interest or disinterest. Thus, the two conceptions of music influence and reflect the philosophical thought on aesthetics between the eighteenth and the nineteenth century. The work is divided into two chapters: the first turns to the Critique of Judgment in its second edition published in 1793 while the second addresses Eduard Hanslick s book first published in 1854. Completion of this work points to the influence of ideas discussed by the authors in the works of Georg Wilhelm Friedrich Hegel and Arthur Schopenhauer, as well as for possible prosecution of the beautiful music from an element disregarded by Kant and by Hanslick: the time.
