The history of the UniChor began in the summer semester of 1990 in one of the corridors of the music wing, still without a permanent rehearsal room. The courageous 20 or so singers sat on discarded sofas and chairs that had to be brought in from the neighbouring seminar rooms.

The aim of this inaugural semester was to see whether enough students would (more or less) reliably and (not always) enthusiastically get through the first rehearsal phase to a small performance. The attempt was successful: in one of the so-called KMS auditions, the choir presented some lighter a cappella works from different eras.

This marked the beginning of the gradual build-up. Initially, the old assembly hall was used as a permanent rehearsal room. The idea of the FORUM as a performance and concert concept slowly took shape. The first focus crystallised: the promotion of student and local composers and musicians, for whom the FORUM was to be available for performances.

The UniChoir's working rhythm (double-semester rehearsal phases etc.) and the manifestation of the recording mode (no auditions, open starting phases etc.) took place in the mid-1990s.

The proportion of performances of contemporary music and regular premières had steadily increased by then. In 1996, the UniChor set up its own composition competition for the "Carl von Ossietzky Prize of the uniChor", which was then organised every two to three years.

A further systematic expansion of the UniChor's work failed due to administrative and financial difficulties, so that the composition competition was handed over to Prof. Violeta Dinescu and the choir's work was increasingly limited to the preparation and realisation of the now traditional Forum concerts.

Since the winter semester 21/22, the UniChor has been under the direction of Silja Stegemeier.
