I used some of the ideas I came up with from that post. I thought about kilrathi physiology to think about how they would have to play an instrument, and that helped me determine placement of notes, then I used some very basic acoustical physics to come up with pitches for an atonal synthetic scale. That also contributed to rhythm (the agility of a Kilrathi's fingers on an instrument for example). From there I thought about warrior-like Earth cultures and their music - a lot of tribal, ritualistic sounding stuff. A lot of awkward dance beats (something where you would need training to be able to dance it it), so that led to me coming up with an asymetrical repeating beat pattern. I used my synthetic scale to come up with a melody and thought about the sounds war-like cultures would like, and kept in mind the idea of cats ( for example, purring. The strings do a tremolo throughout the piece).
The scale I used is as follows (Using post modal chord theory, as I understand it - you assign 1-12, 1 being tonic, and each chormatic note higher being given the next number in the sequence):
1, 4, 7, 8 9, 11, 12
In the key I ended up using (C as the tonic), this became C, Eb, F#, G, Ab, Bb, B
Part of that was me saying "I like how this sounds" and wasn't entirely scientific, although I did use some scientific base in that.
My rhythmic pattern was (in even notes, in my case eighth notes)
1 2, 1 2 3, 1 2, 1 2 3, 1 2, 1 2, 1 2 3, 1-2 3
Some of the ideas discussed in that Kilrathi music thread did find there way in, as you may have heard in the intro.
I don't know if any of that made any sense... if you all are reading that saying... uh... yea... right... I'll clarify.
