Seminaarinmäen mieslaulajat aka Semmarit is a male choir from Jyväskylä, Finland formed in 1989. The group extremely seldom performs traditional male choir music. They deliberately break the boundaries of choral music, and it is difficult to place their music in a specific genre. It is however strongly influenced by rock and roll and pop music. All songs are composed and regularly polled amongst the group members. The songs rarely have instrumental accompaniment; however, in some songs instruments are used for special effects. The instruments they have used included the djembe, the didgeridoo, the kazoo, a toilet door, a zipper in the fly of their trousers and water-filled beer bottles to imitate a pan flute. Some group members also physically use their colleagues as air guitars for playing "instrumental" solos. Imaginative props and choreography are an integral part of the show.
