Arcaño y sus Maravillas was a Cuban charanga founded in 1937 by flautist Antonio Arcaño. Until its dissolution in 1958, it was one of the most popular and prolific danzón orchestras in Cuba, particularly due to the development of the danzón-mambo by its two main composers and musicians: Orestes López and his brother Israel López "Cachao". Such upbeat version of the danzón served as a precursor of the mambo popularized by Pérez Prado, as well as the chachachá created by Enrique Jorrín, a violinist who started his career in the Maravillas. Other important musicians in the Maravillas were pianist Jesús López, timbalero Ulpiano Díaz, violinist Félix Reina and flautist Eulogio Ortiz. Antonio Arcaño, former member of singer Fernando Collazo's La Maravilla del Siglo, founded his orchestra in November 1937 under the name La Maravilla de Arcaño, featuring many of the members of Collazo's group. Collazo himself complained about the similarity in the name, so by 1939 it was changed to Arcaño y sus Maravillas. By then the band had become popular across the island due to hits such as "Mambo". Around 1944, they began to play at radio shows in Havana and the group doubled its roster.
