How is it that music that is so precise and obviously well organised can at the same time move with unforced, almost improvisational fluidity? And how can it be that atonal music sounds so natural and accessible? It's because De Raaff's music is nature itself; geometrically and architecturally stylised music it may be, but no different to the way a tree puts out its branches or how a leaf forms its veins. No different to the cosmologic nature of constellations, wave patterns on water, the pictorial architecture of a murmuration of starlings or a shoal of fish. In De Raaff's work calculation and spontaneity merge into a single, monumental but never massive whole.
