This course is a performance-based ensemble. Concerts will include Fall, Winter, and Spring Upper School concerts as well as Lumina. Agreement to participate in each of these concerts is a mandatory part of enroling in this course. We may perform outside of school as well, as schedule and repertoire allow. Music is significantly more complex in this course, and selections will come from multiple periods of music history, including some modern pieces. Significant outside-of-class time will be needed to master the music; students should expect extra individual rehearsal to be a needed part of this class.
