The publication illustrates the relationship between art and music in the work of Camille Graeser (1892 - 1980), a well-known representative of Zurich Concrete art. His engagement with the music of Johann Sebastian Bach, Paul Hindemith, and Arnold Schönberg paved the way for a new concrete understanding of painting, based on the fundamental elements of form and color. The focus of the catalog is on Graeser's "Loxodromic Compositions" created between 1947 and 1955, along with the corresponding drawings and sketches that demonstrate how the artist developed this new type of composition based on musical structures. A key feature distinguishing this series from all of Graeser's other works is a dynamic, lyrical arrangement of individual forms.
