Hanns Eisler School of Music Berlin regularly cooperates with renowned cultural institutions and ensembles in Berlin and further afield. Out of these various partnerships, innovative projects for numerous school ensembles as well as other events arise.

Hanns Eisler School of Music Berlin cooperates closely with Konzerthaus Berlin, located in the school’s immediate vicinity. Concerts of the school's Chamber Orchestra, Symphony Orchestra, Choir and Echo Ensemble for New Music are held here, as are the event series Musikforum Gendarmenmarkt, the Graduation Concerts and the regular opera gala in cooperation with Department A.

A cappella concerts of the school choir have been held at Berliner Dom and in the Französische Friedrichstadt Church, while the Echo Ensemble for New Music has previously performed at Staatsoper Unter den Linden and in the Guggenheim Museum. The school’s Symphony Orchestra has regularly performed in the Großer Saal at Berliner Philharmonie, while workshops and masterclasses have taken place at the Berliner Philharmonie’s Kammermusiksaal in cooperation with the Berliner Philharmonie Foundation. The various events and graduation concerts of the bachelor and master courses in jazz are held at the Georg Neumann Saal of the Jazz Institute Berlin.

Numerous school events are carried out in cooperation with other ensembles – for example, graduation concerts have included support from Konzerthausorchester, Brandenburgerisches Staatsorchester Frankfurt, Neubrandenburger Philharmonie and Brandenburger Symphoniker. Das Kritische Orchester® Workshop Interactive Conducting – following up an idea of Klaus Harnisch, founded by Christhard Gössling – takes place in cooperation with the Dirigentenforum of Deutscher Musikrat. It is funded by the Federal Government Commissioner for Culture and the Media. Under the patronage of Berliner Philharmoniker, Konzerthausorchester, Deutsches Symphonie Orchester and Rundfunk Sinfonieorchester Berlin, the project is supported by (former) members of these and numerous other orchestras.

The school nurtures partnerships devoted to the practical training and development of students in the scenic musical area with the three Berlin opera houses, HAU (Hebbel am Ufer) and the Bayreuth Festival. The collaboratively conceived productions are designed and organized in cooperation with the school’s directing course. Conducting, correpetition, voice and instrumental students are drawn in depending on the needs, context and size of the productions.

Cooperation with the Staatsoper at Schiller Theater Berlin includes a series of course-integrated internships for students of direction, workshop stage performances by selected direction students, as well as the engagement of voice students.

The biannual, internationally advertised premiere series “Neue Szenen” is held at Deutsche Oper Berlin’s “Tischlerei” and serves to promote direction, voice and instrumental students in the area of contemporary music.

As part of the “Richard Wagner for Children” project, selected direction students assist each year in the Bayreuth Festival, on a special shortened version of a music theater work by Richard Wagner.

The school also cooperates with the company notengrafik berlin in a project that is supported through means from the "TransferBonus" program of Investitionsbank Berlin and the State of Berlin. As part of this cooperation, both partners develop methods and strategies to adjust digital information processing during the creation of performance material to the needs of contemporary composition.
