Souvenir de Porto Rico (Marche de Gibaros) Op. 31, D. 147 is a musical composition by Louis Moreau Gottschalk for solo piano in 1857, during a vacation in Puerto Rico. It is based on the folk song Si me dan pasteles, demenlos calientes, performed by the local peasants known as Jibaros[1]. The piece makes free use of Latin and Afro-American melodies and rhythms almost fifty years before early ragtime and jazz would popularize its use. Souvenir de Porto Rico was written in the fall of 1857 at a sugar plantation just outside the village of Barceloneta, Puerto Rico. At the time, Gottschalk was on vacation with singer Adelina Patti and her father. Gottschalk would decide not to leave Puerto Rico, but instead decided to remain there for what would become another five years. During this period, he composed a number of additional songs that took after the local musical styles.
