Changui is a style of Cuban music which originated in the early 19th century in the eastern region of Guantánamo Province. It arose in the sugar cane refineries and in the rural communities populated by slaves. Changui combines the structure and elements of Spain canción and the Spanish guitar with African rhythms and percussion instruments of Yoruba origin. Changui is thought to be the predecessor of son montuno, which enjoyed tremendous popularity in Cuba throughout the 20th century.

The guitar-like tres gives changui its distinctive sound by following the melodic line of the song and guiding the other instruments.

Changui has an accompanying dance, highlighting the coquettishness of the woman and the chivalry of the man.
