This work consists of nine cobalt blue rectangles against a yellow ground. Snow explores the dynamic interactions between the quadrilateral forms, which vary in shape and size. The idea for The Drum Book came to Snow in 1960 when he played in Mike White’s Imperial Jazz Band in London, Ontario. Snow recalls: “I was staying in a motel with the superb drummer Larry Dubin. He practiced a lot, often just with drumsticks on his knee or a pillow. He had with him a book of drumming exercises. The layout of a page of illustrations in this book—nine rectangular photos—caught my attention. Back in my studio in Toronto I used this layout as the basis for an abstract painting that I titled The Drum Book.”
