Two ensembles are available-Jazz Ensemble Combo (JEC) and an Advanced (JE) Combo. The JEC performs and studies repertoire of the great jazz combos throughout the history of jazz including Art Blakey and the Jazz Messengers, Horace Silver, Cannonball Adderley, and many others. Some jazz vocalists are encouraged to audition for this class. The Advanced JE is a contemporary ensemble that performs very demanding and challenging music of this idiom. A prerequisite is an advanced level of improvisational skills, as well as compositional experience. Transcriptions and the creation of original compositions are integral components of this ensemble.
