4fakultät is a concert series for cross genre improvisation. It is based on a mathematically designed musical score: Four acts of various artistic backgrounds play two sets of their own. These separate sets intersect. All four musicians improvise in a rotating order creating a continuous concert with no breaks or stops. A musical dialogue where improvisation cuts to the bone of genre and style definition: 4fakultät.

Founded in 2016 the concert series takes place four times a year at Künstlerhaus Faktor in Hamburg, Germany. Complementing the single events 4fakultät offers an interdiciplinary working platform to a variety of arists. Derya Yildirim, Kate NV, Anna-Lena Schnabel, Svetlana Maraš, Andrea Belfi, Andi Otto, Nika Breithaupt, Sven Kacirek, Jawad Salkhordeh, Fee Kuerten – all of these musicians are part of the 4fakultaet concept.
