Here are some scales I made up. Sure, they probably already exist somewhere else. But actually - discovered them from some seven-note chords I had stumbled across and scribbled down. For me these are new parent scales.
Except for the Egyptian scale. Got that from Miles's autobiography.
Experiment with using them with seven chords - like you might use a Gmin or Dbmin scale for C7 .. ... ....
blue print is IONIC scale
- means flat [b]
+ means sharp [#]
PS Tasmanian scale is -2, -3
