I liked the idea of splitting the orchestra into high and low of Capricorn. In the spirit of it how about two-note "chords" with short and long notes, perhaps with some of the articulations of Andromeda:
- minor and major thirds
- fourths
- fifths
- sixths
Then you can builld chords putting the lower and higher registers together. Of course the orchestra could also be split up into three non-overlapping regions.
Or simply additions to the chord hits of Black Eye:
- half-diminished
- sus4 and sus4 - think pop music
- open fourth - think metal - ;)
- 1st and 2nd inversion of major and minor chords (and others?)
Ok, the ideas are not really thrilling
