The festival is not only known for it's program but also for the legendary jam sessions that take place. 

Jazz is a universal music style and jazz standards have become the common repertoire of all jazz musicians. This music connects across generations and language barriers. This is evident in Langnau not only in the workshops, but also in jam sessions. They are just as common during the festival as they are in the jazz metropolis of New York. Whenever the opportunity arises, jazz enthusiasts meet on stage. This not only creates musical friendships, but also brings together up-and-coming talent with international stars and long-time course participants with jazz legends. A pleasure for musicians and audiences alike.
