Leonard Harold Breau (August 5, 1941 – August 12, 1984) was a Canadian-American guitarist and music educator. Breau 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.
