The book is dedicated to his former music teacher, Antonio Segura Mesa. This provoked the anger of Martín Domínguez Berrueta for ever. Some members of El Rinconcillo did not look very favorably on Domínguez Berrueta. The most critical of him was Mora Guarnido.

Federico did not dedicate the book to Don Martín, even changing the passage about San Bruno de Pereira who was greatly indebted to the professor. Domínguez Berrueta felt betrayed. He only mentioned him and his companions at the end of the book, in a letter. But Don Martín returned the book and never spoke to him again. Even their families, once friends, became estranged. The teacher died two years later and Lorca later acknowledged his debt to him.
