Young musicians discover the vibrato of violins, violas, celli, and double basses that form the core of Usdan's four incredible orchestras. Each day, orchestra students come together for one hour of full orchestra practice and one hour in sectional instruction. The orchestras perform major symphonic works and collaborate with other Usdan ensembles. Students must have at least one year of prior instruction with note reading. Sixth graders interested in Senior Division must audition.
