SōSI 2021 – Flexible Music

Announcing SōSI 2021 our 13th annual Sō Percussion Summer Institute is officially remote and available to anyone, anywhere from July 11-25, 2021! Whatever your practice, and wherever you are – we hope you will join us!

A note from Sō Percussion…

2020 has reminded us that you can plan for the future (and we do!) but much is out of our control.

Anyway, as we head toward 2021, we still want to plan for our favorite annual event, the Sō Percussion Summer Institute. 2020 taught us that we can successfully offer the magic of SōSI even in online-only circumstances. We are ready to offer breathtaking opportunities online!

Tuition for participation is $1,200. We are excited to offer multiple scholarship opportunities! Check out our FAQ here!

Check out the information about SōSI 2021 here. We hope you can join us! If you’re curious about our last online Sō Percussion Institute, check out the final concert of SōSI 2020 here)

Please email Shelby@sopercussion.com with questions and inquiries. 

We will also be providing an asynchronous SōSI 2021 track for registration for those who need a flexible schedule alongside guest and faculty event audit opportunities!

Information and registration to become available on May 1, 2021!

Flexible Music

Does a musical composition consist of the abstract ideas which animate it? Or is it about the exact sounds a composer hears in their mind’s ear? Must it have notes and rhythms, or could it only be a blueprint for construction? These questions gained new urgency in 2020 when we stopped gathering in rooms together, and when the privilege of access was (once again) thrown into sharp relief.  As we in Sō Percussion started new remote collaborations, we realized that the music we produced during this time would need to have maximum flexibility to work with whatever resources each of us had lying around.

In the spring of 2020, we produced a re-imagining of band member Jason Treuting’s Amid the Noise for video, which was initially composed for what we call “flexible instrumentation.” This piece was in turn influenced by avant-garde works like Terry Riley’s In C. We found that music by composers such as Pauline Oliveros, John Cage, and Julius Eastman already provided a model for how to work this way, and that we have always been more interested in percussion as a realm of openness and exploration than as a collection of instruments and techniques.

These kinds of works have multiple paths of realization. They can happen via remote collaboration or live performance, playable by many possible types of ensembles. For SōSI 2021, we want to focus on the unique challenges and opportunities of flexible music. Participants will take on the idea of artistic openness: composers will explore how and where to relinquish control, and performers will learn how to contribute creatively.

The Institute’s Mission

The emergence of the percussion group as a standard ensemble has been one of the most exciting developments in contemporary western music. Sō Percussion was formed to expand this important voice in the 21st century, taking a cue from groups in North America and Europe, as well as the pioneering composers who inspired them.

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


Applications for SoSI 2021 are closed.

Sō Percussion Summer Institute Opening Concert 2020

Welcome to SōSI! When we founded the So Percussion Summer Institute in 2009, we set out to create the chamber music summer festival we wish had existed when we were students. We launched a two-week program in Princeton, NJ where emerging percussionists and composers could gather and collaborate, benefitting from performing alongside seasoned pros and playing unique works by living composers—often for the first time. Over the last eleven gatherings of SōSI, we’ve done just that, providing hundreds of percussionists and dozens of composers with the opportunity to explore the new, hone their skills, and become part of a community of idealistic creators and interpreters.

This year’s SōSI looks a little different—we’re gathering online, which allows us to welcome artists from around the world—but we are so proud of what these students are creating with us. Enjoy!

When social distance became a necessity (and we faced an abruptly bare concert calendar), we decided to use the time and space to create a new version of a signature work,  Jason Treuting’s Amid the Noise. Written for flexible instrumentation, Amid the Noise lends itself well to  layering and technological artistry. The process of interpreting each movement (some with the quartet, and many more with musical colleagues) helped us understand what felt right for socially distanced creative work – and how we wanted to record and layer it all together. 

This learning process has shaped the structure of SōSI 2020 Online, and we are delighted to premiere the complete Amid the Noise 2020 for you as our opening concert. 

There is much to come over the coming weeks, and we can’t wait to share more work and creative collaboration with the brilliant students of SōSI, and with the greater public. 

Stay tuned, and be well!

-Eric, Josh, Adam, Jason, and Shelby

P.S. – After the show – Jason Treuting will host an Instagram Live to chat the genesis of Amid the Noise – join us on Sō Percussion’s channel –  @sopercussion! 

This is a free concert. Help us continue our work within SōSI by making a donation!  

100% of contributions made during this event will go directly to The Outreach Program

For the past six years, Sō Percussion has partnered during SōSI with The Outreach Program to pack meals for food-insecure families in Mercer County, NJ. COVID had other plans this year, but we’re still committed to The Outreach Program’s great work. When we host SoSI on Princeton’s beautiful campus, our annual food-packing event reminds students that many of Princeton’s neighbors in Mercer County struggle with food insecurity. The percentage of food-insecure residents in Mercer County has grown amidst COVID-19, rising from 8.9% in 2018 to an estimated 13.6% this year. Now more than ever we are honored to partner with The Outreach Program: any gifts to Sō Percussion during SōSI (July 12-26, 2020)  will go directly to The Outreach Program.

After 10 amazing years of SōSI, we have quite a roster of alumni, many of whom have gone on to form their own groups and pursue unique musical interests.  Some of them sent along websites where you can learn more about everything they are doing.

TIGUE: alumni of SōSI 2009


Each year, an amazing team of interns helps us keep this extremely complicated festival going!  Interns join the Sō Percussion team and help us organize gear and other logistics, produce concerts, and keep the ship running day to day.

The bulk of our interns’ duties fall within logistics for a festival which hosts dozens of world premieres by 40-50 participants each summer. They receive free room and board during the festival, and frequently participate in performances themselves. As this years festival is online – the duties and offerings are subject to change and will be announced at a later time.

Applications for our internship program will be made available soon! Come back soon or reach out for questions!
