Cassiopeia
Cassiopeia is the energetic and youthful mixed choir of the University of Oulu Students’ Union. The choir, active since 1978, has had a varying number of singers ranging from sixty students to a hundred. In recent times, however, the number has set to approximately seventy.
The choir’s artistic activities are extremely wide ranging. However, the May Day and Independence Day concerts form the core of the choir’s yearly schedule. Additionally, Cassiopeia organises a varying number concerts every year. Social activities, such as parties, get-togethers and sports, are also frequently organised within the choir.

TeeKu is the greatest choir of students of technology from Oulu in the world. TeeKu was founded during the Wappu celebrations of 1993. There are approximately 20–30 active singers, about half of which are engineering students and alumni and half study in other faculties. The choir is conducted by Sofia Riippi.
TeeKu’s repertoire mostly consists of easy listening, drinking songs and of course traditional songs of engineering students. One larger thematic concert is held each year, plus a varying amount of smaller concerts such as the annual Wappu concert and graduation ceremonies.
