Trova is one of the great roots of the Cuban music tree. In the 19th century a group of itinerant musicians known as trovadores moved around Oriente, especially Santiago de Cuba, earning their living by singing and playing the guitar. According to one writer, to qualify as a trovador in Cuba, a person should a) sing songs of his own composition, or of others of the same kind; b) accompany himself on the guitar; and c) deal poetically with the song. This definition fits best the singers of boleros, and less well the Afrocubans singing funky sones (El Guayabero) or even guaguancós and abakuá (Chicho Ibáñez). It rules out, perhaps unfairly, singers who accompanied themselves on the piano.
