What particularly attracted me [in his painting 'Still-life with Musical instruments', 1908 – 1909].. ..was the materialization of this new space that I felt to be in the offing. So I began to concentrate on still-life's, because in the still-life you have a tactile, I might almost say a manual space.. .This answered to the hankering I have always had to touch things and not merely see them. It was this space that particularly attracted me, for this was the first concern of Cubism, the investigation of space.. ..In tactile space you measure the distance separating you from the object, whereas in visual space you measure the distance separating things from each other. This is what led me, long ago, from landscape to still-life.
