7 different clusters, each containing two or three different pitches.
Ascending pitch order     : 7 6 1 4 5 3 2
Working backwards, new nos: 1 2 3 4 5 6 7 ascending pitch clusters.
        appear in order   : [1] 3 7 6 4 5 2 1 - this could be used as form series, [whim?] 7 : complex
                                - ----- -----  or also  -    -  -   - lengths of variations: simpler
        [or, descending   :[1a] 5 1 2 4 3 6 7 - this could be used for time series, high=short
        [       order           - ----- -----
                                for time series, use [position of?] this row, so that longest become
                                 shorter [l.u.v.?]
                               :fn determining time series, sound time was from row [1a] & rest time from row [1] - or [prog.a?]
                                for each note, an even rhythm would be established
                             extend pitch series to over two 8ves.
