Pepe Sánchez (1856–1918), was the father of the "trova" and the creator of the Cuban bolero. He had no formal training in music. With remarkable natural talent, he composed numbers in his head and never wrote them down. As a result, most of these numbers are now lost for ever, though some two dozen or so survive because friends and disciples transcribed them. He also created advertisement jingles before radio was born. He was the model and teacher for the great trovadores who followed him.
