"ilSUONO Contemporary Music Week is a collaborative endeavor that emerged organically in 2015 out of my, then, five-year friendship with Mic­hele Bianchini and the members of the co­ntemporary music col­lective Ensemble Suo­no Giallo.


The mission of ilSUONO is to provide young emerging composers and instrumentalists unique oppor­tunities for research, artistic challeng­e, experimentation, and growth. In the ideal environment of Sansepolcro, we created a setti­ng to encour­age and inspire. In this environment, a select pool of you­ng artists, spanni­ng over diverse cultures and aesthetic orient­ations, come together to collaborate cl­osely with highly skilled pr­ofessional instrumen­talists and renowned composers from prestigious academic institutions.­

The founding princ­iples that govern this annual project are de­dication, passion, merit, and the desire to explore the endless pote­ntial of the musical sphere." T.P.


Originally from Greece, Theocharis Papatrechas is a composer and sound artist based in San Diego, CA.  

Praised as attaining "beautiful instrumental intensity" and laying out "an intimate narrative" (il giornale della musica), Theocharis's music arises from a search for reasons and sound images that resonate internally. His creative practice masters and utilizes technology to expand sonic possibilities and engage audiences in immersive 3D acoustic experiences.

His artistic portfolio consists of instrumental, electroacoustic, acousmatic, sound art, and sound installation works that involve acoustic components, pre-recorded media, and generative and interactive processes, employing Dante networking systems and ambisonics in multichannel venues.

Renowned groups that have commissioned and premiered his works include the ensemble IntercontemporainNouvel Ensemble Moderne, Mivos Quartet, Vertixe Sonora, Ensemble Schallfeld, East Coast Contemporary Ensemble (ECCE), Divertimento Ensemble, Ensemble Multilatérale. Notable venues, at which works of his have been presented, include IRCAMCCRMA at StanfordSEAMUS at Berklee College, Anchorage Museum, SPLICE InstituteNew York City Electroacoustic Music Festival (NYCEMF), Vienna Konzerthaus, SpazioMusica, University of Montreal, and Shanghai Conservatory of Music.

Hired to diffuse his creative practice into scientific projects and contribute to the ever-growing research community in acoustics, Theocharis has held appointments at the California Institute for Telecommunications and Information Technology (Postdoctoral Scholar, 2022-23), Scripps Institution of Oceanography (Research Associate, 2021-22), and Center for New Music & Audio Technologies (CNMAT) at UC Berkeley (Visiting Composers and Researcher, 2021). His work deals with acoustic data from underwater and terrestrial environments and, through applying research on acoustics, audio engineering, sound synthesis, and spatial 3D and VR audio, purposes to formulate a broader understanding of the impacts of climate change on the environment. 

Theocharis holds a Ph.D. in Music Composition from University of California San Diego (UCSD) where he worked with Rand Steiger, Lei Liang, and Miller Puckette. Other leading institutions he studied at include the Eastman School of MusicIRCAM, and Sibelius Academy.

His music has been released by ArsPublica. His scores are published by Babel Scores.

Since 2015, Theocharis serves as the Artistic Director of the ilSUONO Contemporary Music Week. The program's core mission is to diversify the practice by bringing together emerging music creators of diverse socio-economic backgrounds, ethnicities, cultures, gender orientations, and aesthetics to learn, share, and collaborate. ilSUONO is delighted to have invited exceptional senior composers, among others, Chaya Czernowin, Rand Steiger, Franck Bedrossian, Edmund Campion, Pierluigi Billone, Ann Cleare, Clara Iannotta, and performers such as the ensembles Schallfeld and Lemniscate. For the last three editions (21', 22', and 23'), ilSUONO is proud to have received grants from the esteemed Ernst Von Siemens Music Foundation.
