Overview
The Collegium musicum at the University of Cologne shapes and represents the university’s musical life and offers a wide range of opportunities for students, university staff, and interested members of the public to experience music—both as active participants in our ensembles and as concertgoers.
The Collegium musicum’s ten ensembles cover a wide range of genres, from the large symphony orchestra and choir to chamber ensembles, a jazz choir, a big band, and a children’s choir. Concertgoers appreciate the UNIVERSITY CONCERTS as a diverse concert series that features not only the university’s own ensembles but also a wide variety of guest artists and ensembles.
Making music and experiencing it as part of a group has a significant impact on the well-being of all members of the university community, transcending disciplinary and status boundaries. Even beyond the campus, university music enriches the cultural landscape and forges connections between the University of Cologne and the city’s residents. On concert tours and through national and international collaborations, the members of the University of Cologne’s ensembles serve as cultural ambassadors. The Collegium musicum is a member of the University Music Network Germany.
We always welcome new musicians and singers to our ensembles, as well as an enthusiastic concert audience.

In 2008, he was appointed University Music Director and Head of the Collegium Musicum at the University of Cologne. There, he conducts the orchestra, choir, chamber orchestra, and chamber choir. From 2007 to 2019, he led the Brühl Oratorio Choir. As a guest conductor, he has led ensembles such as the Bochum Symphony Orchestra, the Neue Philharmonie Westfalen, the Boston Modern Orchestra Project, and the Musikfabrik. He regularly collaborates with the Cologne Vocal Soloists and their founder, Fabian Hemmelmann. He has performed at various festivals, such as the Brühl Castle Concerts and ACHT BRÜCKEN, where he conducted vocal works by Ligeti and Morton Feldman’s “Rothko Chapel,” among others. He has served as rehearsal director for, among others, Pablo Heras-Casado (Luciano Berio’s “Passagio,” with ensemble intercontemporain) and Duncan Ward (Manfred Trojahn’s “Les dentelles de Montmirail,” world premiere, with Ensemble modern). Commissioned by the Gürzenich Orchestra, he formed the Cologne Citizens’ Choir in 2022, which he has led ever since. Together with Martin Herchenröder, he served as artistic director of the 2009 George Crumb Festival NRW. Previously active as a pianist and organist, he also co-founded the chamber ensemble sforzato. In his various roles, Ostrzyga has commissioned, rehearsed, and/or premiered many new works, including those by Friedrich Jaecker, Martin Herchenröder, Jan Masanetz, Markus Schmickler, Anno Schreier, Gerhard Stäbler, and Manfred Trojahn.
The BR described his full-length Christmas oratorio “Puer natus est” (2017), with a libretto by Winfried Bohm, as a “resounding success.” His compositions are published by Breitkopf & Härtel, Bärenreiter, Carus, and Helbling. As a music theorist, his focus lies in composition in historical styles and in instrumentation. Ostrzyga presented a completion of Mozart’s Requiem fragment that, for the first time, brings together music-historical perspectives with historically informed music theory and practice in composition, arrangement, and instrumentation. The edition became a bestseller at Bärenreiter immediately upon its release in June 2022. The CD recording was nominated for an Opus Klassik award in 2021 in the category “Editorial Achievement of the Year.”
Ostrzyga has been president of the Network for University Music in Germany since its founding in February 2024.
Ostrzyga received his early musical training (organ, piano, choir) from Bruno Zaremba before studying in Cologne with Marcus Creed (conducting), Friedrich Jaecker (composition), and Peter Degenhardt (piano), graduating in 2005.

Sophia Herber
Sophia Herber earned a master’s degree in German Studies, Art History, and Theater, Film, and Television Studies from the University of Cologne. Her master’s thesis focused on topographical readings of the novels and short stories by the Turkish-German author, actress, and director Emine Sevgi Özdamar (Georg Büchner Prize 2022). She subsequently served for several years as director of the kunst:dialoge project at the Museum Ludwig in Cologne, where she trained numerous college and high school students in dialogic art education and organized art nights. She worked as a freelance museum educator for the Cologne Museum Service, opened art exhibitions, and wrote catalog essays for contemporary artists. While starting her career, she began private voice lessons and continued her vocal training with contralto Francisca Beaumont, who still coaches her today. As a mezzo-soprano/alto, she has performed in Cologne, Bonn, Berlin, Weimar, Leipzig, Potsdam, and Milan, and also appears as a soloist with ensembles of the Collegium musicum at the University of Cologne.
She joined the Collegium musicum in 2008 alongside Michael Ostrzyga and has served as its executive director since the summer of 2011. In addition to program planning and organizing the UNIVERSITÄTSKONZERTE series, she is responsible for design and public relations. In 2021, during the COVID-19 pandemic, she initiated the “Totentanz” project. In this role, she not only served as director and host but also taught herself how to use Adobe Premiere Pro, conceiving the project’s music videos and handling both the technical and artistic aspects of their editing.
She has also conceived and organized series such as “Musik im Museum” and the “ResonanzProjekt”—in which music is performed in various university spaces not typically designed for that purpose—as well as the “Große Sommernacht” at Wahn Castle during the Shakespeare Year of 2016. Occasionally, she also serves as a concert host and writes texts for the Collegium Musicum’s program booklets.
