Who is Enrique Jorrín?

Context: The creation of cha-cha-chá has been traditionally attributed to Cuban composer and violinist Enrique Jorrín, who began his career playing for the charanga band Orquesta América. According to the testimony of Enrique Jorrín, he composed some danzones in which musicians of the orchestra had to sing short refrains, and this style was very successful. In the danzón "Constancia", he introduced some montunos and the audience was motivated to join in singing the refrains. Jorrín also asked the members of the orchestra to sing in unison so the lyrics might be heard more clearly and achieve a greater impact in the audience. That way of singing also helped to mask the poor singing skills of the orchestra members.
