The All-Chesterfield Orchestra (ACO) unites the six most talented musicians from each high school orchestra in Chesterfield County. Preference is given to Varsity Strings members demonstrating exceptional musicianship. This demanding event spans two days, requiring punctuality and full attendance throughout. Prior to the event, participants must diligently practice and master their music independently. Audio practice files will be added to the Google Folder if they are available. ACO members receive a prestigious medallion and certificate, along with two points toward senior honor cords, recognizing their dedication and skill.
