SōSI 2023

Program Overview

The Sō Percussion Summer Institute (SōSI) brings together ambitious composers and performers for two weeks in July 2023 on the campus of Princeton University in Princeton, NJ, to learn and perform in a hands-on environment with the world-renowned ensemble Sō Percussion and their collaborators.

15TH Anniversary Celebration! 

We can’t believe SōSI has been going strong for 15 years! The more than 350 alumni of SōSI have contributed so much to the percussive world since we started in 2009. For SōSI 2023, we are going to continue looking ahead to the future of new ideas in percussion music, as well as bringing back music written during past festivals. We will also be celebrating 10 years of the composition program by featuring the percussion music of our Director of Composition Andrea Mazzariello.

This unique two-week program allows participants to experience Sō Percussion’s processes for creating and premiering new work firsthand. SōSI features mentorship from the members of Sō Percussion, our composition faculty, a diverse array of guest artists, our artist-in-residence, Princeton faculty, and other special guests.

As in past years, percussion students at SōSI will be placed in groups to perform in numerous concerts and masterclasses throughout the two weeks. Composition students will study with Andrea Mazzariello as well as with members of Sō Percussion & guest faculty. Both undergraduate and graduate composers are welcome to apply. Composition parameters and guidelines are available through the application portal.

Applicants should apply in only one category; however, those with an interest in both performing and composing are invited to inquire about opportunities to explore both during the Summer Institute. Email us at adam@sopercussion.com.

The Institute’s Mission

The emergence of the percussion group as a standard ensemble has been one of the most exciting developments in contemporary music. Sō Percussion was formed to expand this important voice in the 21st century.

Since its inception in 1999, education has become an increasingly important part of Sō’s mission. Its members share a firm belief that inherent in an artist’s career is a responsibility to pass on practical advice and mentorship to young artists. The Sō Percussion Summer Institute seeks to fulfill this promise by providing a unique educational opportunity to percussionists and composers at one of the most critical stages of their development. The program offers a hands-on experience that brings the practical and theoretical together:

      • Commissioning/Creating new music
      • Fruitful collaboration with and among artists
      • The rehearsal and development process
      • Performance

The 2023 Sō Percussion Summer Institute is supported by New Music USA’s Organizational Development Fund with support in part from the New York State Council on the Arts with the support of the Office of the Governor and the New York State Legislature, and supported, in part, by public funds from the New York City Department of Cultural Affairs in partnership with the City Council, with support from The Aaron Copland Fund for Music, Howard Gilman Foundation, and the Geraldine R. Dodge Foundation. Support for the Organization Development Fund is also provided by contributions from the New Music USA endowment.
