He started to play clarinet when he was 18 years old. From 1969 until 1972 Jörgensmann took private lessons from a music teacher at the Folkwang Hochschule in Essen. At the same time he started working with fellow musicians from the Ruhr industrial area. During this time he was also a chemical laboratory assistant. After a one and half year hitch in the German Army Jörgensmann worked with handicapped children and studied social pedagogics, but he never brought it to a conclusion. Since 1975 he has been a professional musician.
