This work demonstrates his debt to Falla, with whom he collaborated closely during these years in Granada, researching popular types of music and literature. He is also indebted to the compilations of couplets by Francisco Rodríguez Marín, Antonio Machado Álvarez and other folklorists, as well as to the Arab, Persian and Turkish poetry of the 19th century compiled by Gaspar María de Nova Álvarez. In addition to this is the “poetic memory” of his childhood in the Vega in Granada. The summer of 1921 in Asquerosa (Disgusting) he learned to play the guitar.
