Javier Arau (September 30, 1975) is an American composer, saxophonist, conductor, theorist, author, and entrepreneur.

Arau's 'Missouri Blues' toys with the edges of funk and fusion, and he puts grit into his tone to match.

[8] Javier's compositions have received awards from ASCAP, BMI, DownBeat Magazine, and IAJE, and are published by UNC Jazz Press and Dorn Publications.

[9][10] Arau has published his "Augmented Scale Theory,"[11] which helps bridge the gap between the chromatic tendencies of modern jazz and the diatonic roots of traditional jazz harmony, enabling the improviser to play creatively over such challenging material as Coltrane's “Giant Steps” and Wayne Shorter classics.

Javier is currently writing a book entitled "Anatomy Of A Melody: A Jazz Improv Primer for All Instruments".
