From the newly released Agnes Martin: Her Life and Art, by Nancy Princenthal:
Martin’s mature paintings (she destroyed most of her early work) are incontrovertibly right, in the sense that they convince us that not a single preliminary decision or incident of execution could have been changed without damage. Composed of the simplest elements, including ruled, penciled lines and a narrow range of forms—grids, stripes, and, very occasionally, circles, triangles and squares—and painted in a limited palette on canvases that are always square, they reveal an esthetic sense that is, as her friend Ann Wilson said, the visual equivalent of perfect pitch.
What a thing to say about a body of work: pitch perfect. Having just gone through the arduous task of culling through my archives and throwing out a lot of old work, that perfect pitchness looms as a specter. We all want to achieve that with every piece, but it is a rare state.
I am not a perfectionist (which would be a crippling quality for anyone who learns by doing), but my decision to keep a work or to give it a toss came down to which pieces could hold that essential tension, a version of Wilson’s perfect pitch. There has to be something in the intrinsic energetics of the work that holds the parts together in a precarious, “this almost doesn’t work but it does” delicate balancing. In its own way it is a kind of immutability: that a particular painting is just what it must be, and wouldn’t work in any other form.
Noguchi said, “For artists there is no such thing as progress. It’s only a deepening.” That’s definitely the direction.
And apropos to that, another passage from Princenthal’s wonderful book:
To be abstracted is to be at some distance from the material world. It is a form of local exaltation but also, sometimes, even disturbance…Agnes Martin, one of the most esteemed abstract painters of the second half of the twentieth century, expressed—and, at times, dwelled in—the most extreme forms of abstraction: pure, silencing, enveloping, and upending.
