Call-response

Coro-pregón (or coro-guía, coro-inspiración) in Afro-Cuban music and Cuban-based Latin music (mainly from the United States and Puerto Rico), most of all salsa, but also in some non-Cuban genres like merengue, refers to a call and response section between the lead singer and the coro (chorus). It is found in most Cuban genres, for example son and son montuno, rumba, cha-cha-chá, timba, and many more.

The practice of call and response singing probably stems from traditional African music and was brought to Cuba by slaves. It can still be found in its ancient form in Cuban religious music. Vocal improvisations are also based on market vendors' chants, called pregón.

The lead singer usually improvises both melody and lyrics (although most singers have some standard lines which they use quite frequently). This is called guía or pregón. The term pregón also refers to a vocal improvisation without coro, and a genre in which such vocal improvisation is very important. The main language for guías is Spanish, but other languages like Bantú, Dahome, Lukumí and Congolese are sometimes featured as well, either for complete guías or as single words within a Spanish guía. In timba music, English and Spanglish are sometimes used as a special effect. Many singers have a special word or phrase that they insert into their improvisation as a trademark. The most famous example is Celia Cruz's "¡Azúcar!" ("Sugar!"). In timba and other more recent styles, the pregón is sometimes replaced by a rap section.
