MT00108.000 35mm Radiating lines Microtone tests, suggested by John Cage. Neg from 0 to 125 feet. The first 60 feet is essentially a scale test. From 60 to 125 we have neg of “melody”. Then we have a section from 125 to 185 which is a print of melodic part; and 185 to 240 feet is second copy. (See HDSR SO15B10.019)
