All City Orchestra Summer Academy Logo

One year after an exciting inaugural season at the Mann, the School District of Philadelphia, the Mann Center for the Performing Arts, The Philadelphia Orchestra, and Project 440 came together once more to co-present the second annual All City Orchestra Summer Academy – this time virtually. The program culminated with a virtual performance of Farandole from Georges Bizet's L'Arlésienne Suite No. 2, conducted by the wonderful Yannick Nezet-Seguin!

Frequently Asked Questions

When is the Academy?

ACOSA 2020 was held from July 20th to 31st in a virtual format.
The final concert date is on Tuesday, August 11th at 11:00 AM and will premiere on our Facebook page.

How many students get in?

While there is not a limit set for the number of students accepted into the program, ACOSA requires the diverse breakdown of instrumentation as is standard to an orchestra.

Our goal is to facilitate an orchestra comprised of 60-80 musicians.

What is “Summer slide?”

“Summer slide” is the tendency for students, especially those from low-income families, to lose some of the achievement gains they made during the previous school year. Most students lose two months of mathematical skills every summer, and low-income children typically lose another two to three months in reading1. Furthermore, this loss compounds year-after-year, meaning, for every summer without access to educational resources, the achievement gap grows larger and larger between students.
Preventing summer slide is most effective when community organizations work together to encourage kids to read, practice their instrument, dribble a basketball, or generally engage with whatever it is they are passionate about2. Utilizing the summer months as a time to stay sharp on a respective skill is paramount to combatting summer slide.
