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.
