'visiting improvisation‘ is an attempt to explore the various fields in music where improvisation takes place. Many musical cultures incorporate improvisation as one of their main characteristics. The film project tries to find out where sources of improvisation lie and how we can gain access to that state of flow which allows a musician to reach his full musical potential and creativity. I had the experience that lyrics and harmony during improvisation seemed to be poured through me as if they were coming from an outer source. Scientific tests by Prof. Charles Limb show that during improvisation, the brain areas of communication and subconsciousness are active while areas of reason remain silent. In talking to musicians and musicologists from various genres and by filming artists during their performance, I want to illustrate the phenomenon of improvisation - as if opening windows to different musical landscapes.
