He was taught by his father to play the guitar at a young age. When his mother died in 1947, he went to live with his older sister and was raised in the town of Coamo where he received his primary education and studied music. When he was 11 years old, he participated in a local talent contest with a trio that he had formed. He played the guitar and sang for the trio and they won the first place prize. One of his teachers suggested that he attend the Jose I. Quinton Academy of Music, which he did. It was there that he learned to play the trumpet. In 1956, Valentín moved with his family to New York City, United States, where he attended George Washington High School and continued to take music lessons.
