"Chronos" is a composition by the great jazz pianist, Aaron Parks. Originally arranged for a quartet consisting of piano, upright bass, drums and tenor saxophone, I sought to arrange the piece for a sextet consisting of trombone, alto saxophone, tenor saxophone, guitar, upright, bass, and drums. This thesis outlines my process as I transcribed "Chronos" from the original recording and then arranged it for a new ensemble. It also discusses the difficulties faced in all the phases of the project from transcribing to rehearsing and performing the work. My arrangement is included with the thesis for those who wish to analyze the music as well as a recording of a live performance of my arrangement at The Nash in downtown Phoenix on April 7th, 2015.
