Sonad workshops aspire to the highest possible levels of artistic and expressive excellence. Further, we bring life to Sonad’s mission to use participatory arts projects to build community across lines of difference. Sonad Glen Brook workshops serve as part of Sonad’s ongoing research to learn how the music-coaching model is reflected in other arts disciplines. Sonad aspires to make the experience of crossing human divides available to everyone, in a variety of disciplines, regardless of previous experience.

“If we genuinely want the horrors of the world to cease, we must  fully commit ourselves to the concept that every voice, every life, is a treasure to be love, and protected, and cared for.”            Eric Stumacher

“Thank you for an absolutely incredible, incredible week. It was just fantastic – there are not even words I can use to describe it. I met such wonderful people, reconnected with friends from college, played amazing music  –just to spend four days surrounded by other talented artists, listening to incredibly beautiful music all day everywhere I walked — it was just phenomenal – and today, the Shostakovich was incredible—and I loved the Tetris, and the Brahms of course always makes me weep — and the readings were beautiful.“  ME

 “Basic friendliness. Good projects. Composer group had multiple good outcomes. Good food, facility contributed to good atmosphere and good working conditions. Nice combination of fun and work. Lots of wonderful people around, and an atmosphere that encouraged nourishing conversation as well as fun.” JS

 “The participants in the painting segment were BRAVE, enthusiastic and curious, like young children first discovering the glory of color. It was refreshing to watch these artists discover another venue for their voice.” JT

 “ I left feeling extremely in touch with who I was as a person.  I felt loved.  I felt appreciated. And, most importantly, I felt alive. This workshop awakened a spirit in me that was dead for so long; a spirit that will not be vanquished so easily anymore.  Thank you!” BP

MARJI GERE, violin

Marji Gere, violinist

MARJI GERE lives and works in Somerville, MA. As a violinist, she is dedicated to the chamber music repertoire and lifestyle, and is most passionate and at home in mixed ensembles (surely the result of growing up in a house with a pianist and two woodwind players). Outside of the chamber, Marji writes libretti and essays, draws cartoons, studies Spanish, welcomes children into the wild world of music, and leads workshops in “active listening” (most recently at the Newport String Project in Rhode Island, the Habla Institute in Mérida, Mexico, and the Harvard Graduate School of Education.)

DAN SEDGWICK, pianist/composer

Dan Sedgwick, pianist:composer

Nurtured by Burncoat High School’s ear-opening music department in Worcester, MA, DAN SEDGWICK studied music at Harvard and then Rice University, graduating with a doctorate in composition in 2009. His current and recent composition projects include theatrical chamber music interwoven with spoken text (for the Sonad Project and Dilijan Chamber Music Series of L.A.), an assortment of rounds in experimental tunings, and a sonata for violin and piano (for violinist Marji Gere). As pianist, Dan has performed chamber music for the Dilijan Chamber Music Series of L.A., Newport String Project, Apple Hill Summer Concert Series, Equilibrium Concert Series, Hill & Hollow Music, and many others.

JOHN STEINMETZ: composer/coach


John’s Quintet has been released on CDs from the Borealis Wind Quintet (Helicon HE 1030) and the Camerata Quintet (Crystal CD756). His Etude No. 5 can be heard on “Bassoon Images” by bassoonist Benjamin Coelho (Albany Records TROY 608). His Sonata for bassoon and piano has been recorded by Michael Burns and Inara Zandmane (Mark Masters 8084).

One and Many, which features children and guest musicians performing alongside a professional ensemble (including sections composed by the children), was featured by the Apple Hill Chamber Players on their “Playing for Peace” tours in the Middle East and Northern Ireland. Mixed Blessings and War Scrap were commissioned by the innovative Los Angeles series Pacific Serenades. Prairie Blessings combines a solo bassoon with a computer, electronics, and slides of unplowed Illinois prairie. His sextet Simple Pleasures was commissioned by the South Bay Chamber Music Society to commemorate their 40th anniversary in 2003, a month before the first performances of his new Concerto for bassoon and orchestra, commissioned by the Los Angeles Chamber Orchestra, the Keene Chamber Orchestra (NH), and the Santa Rosa Symphony. In 2009 the Amman Symphony Orchestra in Jordan premiered his Together for orchestra, beginning string players, and guest musicians playing local music (in this case, playing the traditional Arabic instruments oud and qanun).

John has also written comic pieces that poke fun at the concert ritual and other human foibles. In Possessed a solo cellist speaks the thoughts that run through a performer’s mind during a concert. The Creation of the World for solo bass covers the whole of history with music, a beach ball, a headlamp, and individually-wrapped cheese slices. What’s Your Musical I.Q. (A Quiz) combines musical examples and test questions to parody music appreciation classes, standardized tests, and magazine quizzes.




Gazebo classroom for the authors group

      The authors group at the Sonad Glen Brook Workshop will consist of up to 8 participants of various ages, backgrounds, and experience levels. Participants in this workshop will write a 1- 2 page work based on a movement of chamber music in the workshop. The chamber music work will be selected upon your acceptance, in consultation with the coach.  At the workshop, each of you will workshop your composition, giving and receiving constructive feedback.  You will have extensive opportunities to work with the live musicians playing and coaching the piece of music you will be focusing on. Ultimately you will  present your work in the concert at the end of the workshop. There will also be opportunities for all of you to work with music and poetry, as part of our goal is to encourage cross-pollination among the arts.


The Sonad Glen Brook Workshop will include a composers’ ensemble of 3-4 members. Upon admission to the workshop, each ensemble member will consult with the coach and begin composition of a short piece (5 minutes or less) for the group. At the workshop the ensemble will rehearse and perform each other’s pieces. No previous composing experience is necessary. Compositions may be in any style.                                                                            


During the workshop we will  learn how to make the notation, the compositions, and the performances as communicative and expressive as we can.Our approach will focus on amplifying the most successful qualities in every piece, guided by each composer’s ear and taste. Composers are encouraged to write for the full ensemble, but may choose to write for a subgroup.  Compositions may be  any length from 30 seconds to 5 minutes. 

Composers will need to bring clear, easy-to-read scores and parts. (As players, you know what it takes to make parts easy to read.) Music may be handwritten or computer printed; bring extra paper and/or your computer so that you can make revisions. We will have a printer on hand.
