Sibley students may participate in Band, Choir or Orchestra. Ensembles are designed to expand students’ skills and knowledge in music literacy, music theory, music history, improvisation, and their playing or singing technique. Performances take place throughout the year. Out-of-school ensembles are available for interested students. Advanced Placement Music Theory is offered as an in-depth study of how music “works,” how it affects the listener, the composer’s intent, and the performer’s choices.
