The Moving Orchestra

Sparked by informal jam sessions in living spaces, The Moving Orchestra is an eclectic mix of musicians and dancers from all backgrounds in New York City. The ensemble specializes in workshopping programs heavily based on improvisation, featuring 6 - 12 performers made up of recurring and new artists. The programs are developed utilizing the skills and personalities of each performing group as well as the possibilities of each venue.

The Moving Orchestra's inception began at the very end of the summer of 2019, when six musicians came together for a friendly jam session in Joey Chang's living room. Lim and Chang, with the help of Carol Chave and Thomas Woodman as dancers, began workshopping ways to produce engaging group-improvisation performances. Using a larger living space as a stepping stone, the ensemble started a monthly performance series, advertised on Groupmuse, in unusual venues throughout New York City.

The ensemble is named "Moving" in reference to its performers moving as well as its programs being held in different venues, and "Orchestra" because of its multidisciplinary artists coming together as one.

Based in New York City, Impromptuo is an innovative improvisation-focused duo made up of violinist Katherine Kyu Hyeon Lim and pianist Joey Chang. The duo has been commissioned and presented by Metropolis Ensemble, House of Yes, (Le) Poisson Rouge, Fifth Wall Performing Arts, and National Arts Diversity Integration Association in 2020. They have also performed as part of the Variousound Sessions 2020 Residency, and co-founded The Moving Orchestra in 2019. Though primarily trained in European classical music, Impromptuo draws influence from traditions of free jazz, experimental electroacoustic music, etc., and suggestions from you!

Lim’s and Chang’s paths as improvisers crossed as the two began jamming together at the start of 2019. Having both undergone training at The Juilliard School, they looked beyond the world of European classical music and came to the practice of free improvisation. As the duo performed more and especially into the COVID-19 pandemic with countless live-streamed concerts together, free improvisation became an essential part of their programming, presenting music eschewing labels and rather combining the duo’s multitude of influences.

Impromptuo uses its classical training and improvisation as a means to present programs full of spontaneity and which question the classical tradition, whether it be open-score works or pieces of the classical canon with added improvisations, while remaining true to its identity and background. Impromptuo blurs the borders between musical styles with the intent to strip away perceived hierarchies in today’s musical traditions.

Impromptuo is a recipient of a Chamber Music America Ensemble Forward Grant, made possible with generous support from the New York Community Trust., which has allowed them a prodigious opportunity to work with composer/multi-instrumentalist Tyshawn Sorey.

Unison Quartet

Formed in the fall of 2018 by Juilliard students Mary Grace Johnson, Katherine Kyu Hyeon Lim, Hannah Burnett and Iona Batchelder, the Unison Quartet has been selected to participate in the Juilliard String Quartet Seminar in May 2019, and in Perlman Music Program’s Chamber Music Workshop and Aspen Music Festival’s Center for Advanced Quartet Studies for the summer of 2020 and 2021. Members of the quartet have been prize winners in the Fischoff and MTNA chamber music competitions and have spent summers of 2017 and 2018 at Kneisel Hall Chamber Music Festival, where they met. Dedicated to the performance of 20th and 21st century chamber music, they have recently performed works by Bartok, Shostakovich, Gubaidulina, and Schoenberg in unconventional venues across New York City. The quartet has studied under renowned chamber musicians Ron Copes, Astrid Schween, Joel Smirnoff, Roger Tapping and Laurie Smukler.


Groupmuse is an online platform enabling communities to come together around great art – an online social network that connects musicians directly to audiences through sociable and connective chamber music gatherings. Before COVID-19, Groupmuse would organize hundreds of chamber music concert house parties (called groupmuses) every month. When the Pandemic struck, the platform quickly moved all our operations online — giving musicians a container with which to hold their live-streamed performances in a socially connective way. Since mid-2020, Lim is a Groupmuse staff emcee and a member of their musician co-op founding council who work closely with the Groupmuse team to develop the platform for musicians and audience.
