Leonard Harold Breau (August 5, 1941 – August 12, 1984) was an American-Canadian guitarist. He blended many styles of music, including jazz, country, classical, and flamenco. Inspired by country guitarists like Chet Atkins, Breau used fingerstyle techniques not often used in jazz guitar. By using a seven-string guitar and approaching the guitar like a piano, he opened up possibilities for the instrument.
