National and international jazz musicians were invited to the NDR for the Jazz Workshop series. A number of ten to twenty musicians could rehearse for some days and finally present their results to the North German listeners in a live studio concert. The organizer focused on offering some space for experimenting to different musicians who otherwise would never have played together, and to free them from their daily commercial pressures within that period of time. Even though all predominant jazz styles were represented in the workshops, the focus lay on modern jazz, especially on bebop, hardbop and cool jazz. This was later completed by some new styles such as fusion, jazz rock and world music.
