IN MEMORY: I REMEMBER ERV WILSON

Invited are all memories and/or comments in tribute to Erv Wilson. Please post your own recollections below or just share your thoughts in memory of this man.

A 22 TONE 11 LIMIT CONSTANT STRUCTURE FORMED FROM A SPECIAL HEXANY STELLATION METHOD

This 22 tone scale of Wilson's believed to be from 1967 was found in a series of papers, charts and scales based  stellating Hexanies in  i have not seen before. One particular method resulted in the example below which seems to form the core of the scale above. Wilson took the 1-3-7-11 hexany and stellated it with 5 and /5 to complete the 8 basic triads found within which results in the 14 tone structure to the left. The result of this type of stellation has unexpected results. for instance 4 other hexanies are formed each which occurs twice.  All involve the added 5 plus three factors of the 1,3,7,11 set.  Because of the relationship of most of the added pitches to this stellate being 3/2 above and below, to form this 22 tone scale. 4 more hexanies also appear. The result is one of many 22 tone scales that contain a great variety of compact hexany subsets. 

SOME 5 LIMIT PENTATONICS (1982)

This is an unlabelled set of pentatonic scales in rotation in what first appeared to be a process similar to that used in his Purvi papers but was not in the end. Adjacent pages carry the year 1982. This set of 5 limit scales he has mapped over 53 squares with the whole set comprising 17 different pitches. In 53 unit sizes would be 53232323-53232323-9 implying two tetrachordal like blocks of 4/3 repeated with a 9/8 disjunction. Each interval shift involve the difference of a 25/24. The paper deserves more more attention. Comments and observations are welcome on this one.
