Vioilin and Pipe, 1913, by Georges Braque
Collage helped Braque to realize that, "color acts simultaneously with form but has nothing to do with it,". He made collages to inspire painting compositions, but also as works themselves. In Violin and Pipe, he chooses a stringed instrument as his subject matter. Since there is no concrete evidence that this is a violin, one can understand better how Braque is studying the shapes within the object and pulling them apart to move them around, as if shuffling a deck of cards.
By using collage, Braque created a new relationship between "true" and "false". The materials he used were fragments of the "real world", so were more real than a painted or drawn object. And yet, as artworks they were obviously false because the artist were makong real fragments play unreal roles in a flat, pictorial world.
