An insight into the work by composer and pianist Herman D. Koppel with the American Cantilena Quartet before the first performance of his piano quartet 'opus 114' in 1986. The film is shot at Louisiana, the museum of modern art north of Copenhagen, which serves as a setting literally rich in images. The director and founder of the museum, Knud W. Jensen, talks briefly about Louisiana and what art means to man. Herman D. Koppel also plays a piano piece by Carl Nielsen - conveyed in the film as a study in fingers dancing on the keys.
