Leonard Joseph Tristano (March 19, 1919 – November 18, 1978) was an American jazz pianist, composer, arranger, and teacher of jazz improvisation.
Tristano studied for bachelor's and master's degrees in music in Chicago before moving to New York City in 1946. He played with leading bebop musicians and formed his own small bands, which soon displayed some of his early interests – contrapuntal interaction of instruments, harmonic flexibility, and rhythmic complexity.
