Mexico, D. F. 1927. Like Partch, he realized such Harmonic Constructs were not scales and added first the 6 pitches of the 9 limit plus the 21/20 and the 16/15 and their inversions which he illustrates: 1/1 21/20 16/15 10/9 9/8 8/7 7/6 6/5 5/4 9/7 4/3 7/5 10/7 3/2 14/9 8/5 5/3 12/7 7/4 16/9 9/5 15/8 40/21 2/1 -- Kraig Grady North American Embassy of Anaphoria Island http://www.anaphoria.com
