ORDER OF CLUSTER COMBINATION TONE
BASS NOTES IN ORIGINAL ROW
ANALYSIS I - CLUSTERS
21st May
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.
[Diagrams, trigonometry and calculations]
