The Orange County Youth Symphony Orchestra is the official youth orchestra of Orange County. Winner of the 2012 American Prize in Orchestral Performance—Youth Orchestra Division, the non-profit OCYSO provides the highest level of pre-professional orchestral training for young musicians in Southern California. Conducted by Music Director Daniel Alfred Wachs, OCYSO’s mission, to introduce great music into the lives of young people, is fulfilled in part through its highly acclaimed “Concerts for Fifth Graders,” in the Renée and Henry Segerstrom Concert Hall at Segerstrom Center for the Arts. This series, presented by the Philharmonic Society of Orange County, has provided music education for more than 500,000 students. Additionally, OCYSO presents a concert series in the historic Memorial Hall Auditorium at Chapman University.
