Curet Alonso's mother was a seamtress and his father a Spanish language teacher and musician who played in the band of Simon Madera. He was two years old in 1928, when his parents divorced and together with his mother and sister moved to Barrio Obrero, located in the Santurce section of San Juan with his grandmother. His daily live experiences while living in Barrio Obrero greatly influenced his work as a composer. There he was raised by his grandmother and received his primary and secondary education.

Among his childhood friends were Rafael Cortijo, Ismael Rivera and Daniel Santos. 　　After he graduated from high school, he enrolled in the University of Puerto Rico where he studied journalism and sociology. He worked for the United States Postal Service, a job which he held for more than twenty years. All the while he continued to compose songs.
