The lectures given by Roland Barthes at the École Pratique des Hautes Études certified the death of rhetorics (L´ancienne rhétorique, 1964-1965); but he wrote at the same time an important paper (Rhétorique de l´image, 1964) that hypothesizes its survival in non-linguistic "texts", more specifically in advertising pictures. Why not in musical works? Barthes studied a Panzani advertisement; we consider Debussy´s Soirée dans Grenade. We first paraphrase Barthes´ analysis (a semiotic analysis using rhetorical concepts, leading to a reception analysis), leading to an understanding of the links between La Soirée and the poetic texts that Alfred Cortot and Federico Garcia-Lorca wrote about this work. We question Barthes´s definitions of the terms "rhetoric", "sign" and "reception", to realize that our reception analysis is neither a rhetorical analysis of La Soirée dans Grenade nor a non-rhetorical one, but a rhetorical analysis of Cortot´s and Garcia-Lorca´s texts.
