. . . when i first went to seattle and my friends morris graves and others took me to a small aquarium near the in the market near the sound and it cost ten cents and when you got in there were just these boxes of water and i had been warned that if i saw nothing just to wait and after a while a clam went up from the bottom of one of the tanks and went to the top and then having gotten some air sailed back down this way and when he arrived at the bottom that disturbed others and they went up and shortly it was a magnificent display i thought of that when i was at the crown point press on january and i was going to make some prints and i decided to make a series called on the surface i took the whole sheet of paper for the images at the beginning and i cut the same size up into different shapes with chance operations sometimes with straight lines and sometimes with curved lines and then placed the templates at chance determined points and turned them according to which of 360 degrees and when they crossed the surface at the top i then divided the template so that the work began with large shapes and ended after 35 prints with very small shapes and it went down gradually to the golden section in 35 degrees i enjoyed that work so much and then i had the project of a piece for orchestra i decided to do it the same way to cut the music paper up with the same means and to put the templates at chance determined points on the music paper and the whole paper would potentially be sound but there would not be any space between ledger lines let’s say and the next ledger lines of the next instrument so that everything would be sound whatever you’d hit then i noticed that whereas for the etching the top of the paper was important and going down was interesting for music going up and going down were not interesting what was interesting about music was going from the left to the right and so i had to change the direction and the meaning of the chance operations . . .
