Charlie Banacos (August 11, 1946 – December 8, 2009) was an American pianist, composer, author and educator, concentrating on jazz. Banacos created over 100 courses of study for improvisation and composition. His concepts of teaching and his courses influenced educators since the late 1950s. He was the original author of courses named "Hexatonics", "Intervallics", "Tetratonics", "Superimpositions", "Harps", "Overlaps", "Bitonal Pendulums", "Double Mambos", "Twenty-third Chords", "Tonal Paralypsis", and "Triad Pairs," among others. These and many of his other terms for his courses have become part of the basic lexicon in jazz education.
