Alfredo Tamayo, born in Mérida, Yucatan, is reputed to be the composer of Sueño (Soñó mi mente loca) (Dream, My Mad Mind Dreams), published in 1909 in Cancionero de Chan Cil. In 1920 Manuel Ponce, accused of plagiarising the tune as one of the many folksongs that he harmonized, commented that he did not know ‘the name of the author of that popular song—he has talent’.
