“Beau soir” (“Beautiful Evening”) is set to a poem by Paul Bourget. The poem paints the picture of a beautiful evening where the rivers are turned rose-colored by the sunset and the wheat fields are moved by a warm breeze. Debussy uses a gently flowing triplet rhythm in the accompaniment, which contrasts the duplets that drive the light melody. The piano and voice partner to create the sensation of peace that one might feel in the evening in nature, fitting the post-Romantic stye. As any evening fades, however, so does the mood of the piece, and the song modulates from E major to F-sharp minor. The piece reaches its climax when the melody reaches a high F-sharp, paired with the word “beau”, about two-thirds through the piece, before entering its modulated conclusion.
