Poulenc made his début as a composer in 1917 with his "Rapsodie nègre", a ten-minute, five-movement piece for baritone and chamber group; it was dedicated to Satie and premiered at one of a series of concerts of new music run by the singer Jane Bathori. There was a fashion for African arts in Paris at the time, and Poulenc was delighted to run across some published verses purportedly Liberian, but full of Parisian boulevard slang. He used one of the poems in two sections of the rhapsody. The baritone engaged for the first performance lost his nerve on the platform, and the composer, though no singer, jumped in. This "jeu d'esprit" was the first of many examples of what Anglophone critics came to call "leg-Poulenc". Ravel was amused by the piece and commented on Poulenc's ability to invent his own folklore. Stravinsky was impressed enough to use his influence to secure Poulenc a contract with a publisher, a kindness that Poulenc never forgot.
