'might as well post this little thing that never became anything, a year or two back... (here's to stumbling over one's own fingers...)

It was supposed to have some lyrics, sung by merchant, lamenting the fact that those nice D'ni people, who had made him so rich and powerful, never seem to come around anymore and how his little empire has consequently crumbled. Never got around to learn any D'ni though - I couldn't find references to the interogative, as I recall and the stuff would be mostly "why?, how?, where?, have I?". Well, the D'ni wouldn't teach their language to erthahrohtahn anyway, I guess.
Here is the general chord progression, if anybody want to run with the thing and improve it:
Am - Am/C - Esus - Ddim
F - Bb6 (or G/h) - Cadd9 - Cadd9
Asus2 - ehm...x22003 - Cadd9 - D - Esus
The rest is just a few variatations of Am and E, with an F and a C thrown in.
Played using whatever arpeggio pattern you feel like.
It should be easy to vary the theme between hardly noticeable background muzak and a more cinematic flair, at some sort of revelatory moment, simply by altering intensity, I believe - if one want to keep orchestration at a minimum.
