hidden crosses!

Of particular note, at least to me, are the "hidden crosses" of
the "otonal augmagic" and "utonal augmagic" chords in Blackjack.

If both otonal and utonal elements are added, it's a "cross like"
structure.

It sounds great, but one has to be careful in the voicing.

For example: E>:Ab^:C:D:D< contains *both* the otonal D and the
utonal D<.

Since they are quite close together the create quite a dissonance,
but if voiced in different octaves the effect is (subjectively) nicer
or at least doesn't seem to have an "out of place" dissonance...
