Six drums: 32", 29", 26", 26", 23", 20" arranged around the player in a perfect circle naturally triggered thoughts of the common rational approximation of the irrational Pi (221) where the infinitely reducing decimal is sequenced by the values 142857. In a fit of fancy I imagined these values as pitches (that is their chromatic distance from 0) where the first trichord is inverted by the second. This led logically to the construction of a symmetrical row where the original trichord is found in its four natural forms- prime 0,3,1 inversion 5,2,4 retrograde-inversion 10,8,11 and retrograde 7,9,6. As these inner relationships are ubiquitous throughout nature I was excited by the thought of composing music organically. As a tone row it must be admitted there were serious limitations but when applied to well calibrated Time, both large and small, the possibilities were remarkable. Later, it became known that some 40 years previous Anton Webern had already stolen my find for his Konzert (op. 24) but I forgave him seeing his theft as a compliment.
