The Coltrane Repertory Ensemble is a repertory ensemble consisting of more advanced students at the school. Participants are selected by audition. In this ensemble, significant Coltrane compositions are chosen as vehicles towards understanding why and how the music of John Coltrane, an icon of Jazz whose breath of creation spans modern music from traditional to futuristic and beyond, pioneered concepts of harmonization. His innovative system was predicated on novel uses of the minor third fourth progression, which attributed to the expanded use of whole tone scales and the twelve-tone system, giving more flexibility to the improviser. Coltrane’s logical resolutions of extended chromatic passages, articulating densely notated compositions and tasteful note placement in slower compositions have become defining factors in Jazz and improvised. All of the above represent challenges unique to Coltrane compositions and an understanding of this great artist.
