These classes function as a link between theory and the actual performance of jazz improvisation. They are conceived as practical extensions of the theory classes above. Students in the lab portion play and practice scales, chords, chord progressions and interconnections, and other aspects of music theory as they relate to improvisational skills. In the ensemble portion (which counts as the Improvisation Ensemble for students placed at this level of Theory and Performance), students learn a repertoire of standards and jazz tunes designed to develop fluency in all 12 major and minor keys. All ensembles are professionally recorded each semester. 1 credit for lab; 2 credits for ensemble.
