Take a major scale... And through it away.
Make 9 tone scales from 'scratch'
Just throw 9 intervals together
C D# E F F# G A A# B (C)
1 #2 3 4 #4 5 6 #6 7 (octave/8)
Then take a straight 8ths rhythm in 7/8, write it out:
♪♪♪♪♪♪♪
Then erase 1 8th note: (.'s will be where 8ths previously were, or think of it as an 8th note rest)
♪♪.♪♪♪♪
Then make all the permutations for taking one note away.
Then take 2 notes away:
♪♪.♪.♪♪
Do this for all permutations, moving on to taking 3, 4, 5, and 6 notes away.
Then add some rhythms togther, I will use the two I wrote
:
|♪♪.♪♪♪♪|♪♪.♪.♪♪|
Then assign notes from thye scale you made up
| C C . D# D# E E | C C . D# . E E |
tuh duh!
This can generate some intersting sounds.
Try using different time signatures, odd and normal ones. Like 8/8 (4/4), 11/8, 9/8, 6/8, etc...
Also try scales with less notes, like whole tone scales, pentatonic scales, mutant freak pentatonic scales with odd intervals.
Then combine time sigs and scales for über crazy rhythms.
Then try to make melodies out of it, skip octaves, insane strin skipping from the low B and high E, all that jazz. Hell, try sweeping, it comes up with weird sounds.
