Fwd: A great new keyboard pattern in Blackjack (for Joseph Pehrson)

Did anyone notice that with this keyboard pattern, each chord looks
like a subset of a diminished seventh chord on the keyboard. In fact,
if you play what looks like a diminished seventh chord arpeggiated
all the way up and down the keyboard, you get the Mohajira scale, or
what Graham Breed calls (I think) the "neutral diatonic" scale.
Graham uses _still other_ chords with this scale, such as
the "neutral seventh chord", which is obtained in a majority of
positions on the keyboard when using the pattern TT-TT-TT. Which
reminds me, the pattern P5-P5-P5 gives you a nice "just" augmented
triad (in some inversion) _everywhere_ on the keyboard.

Thanks, Paul... I'll try this!
