Creating Cold

So for the past couple of days I've been turning my energies to creating cold sounds. I've come up with a neat idea or two out of it. Initially I was working on a phase shifting figure. It's melodically based on the whole tone scale and consists of four different patterns (it's a piano part). In the right hand the rhythmic pattern is a two-bar figure in 4/4 and the melodic fgure takes up 7 of those eight beats. The left hand part consists of another different two-bar 4/4 figure and the melodic material took six of the eight beats. So it wound up taking 40 or 50 something bars before it repeated. I thought it was kinda cool but it was a little static so I'm trying to see how I can incorporate parts of it in perhaps a more interesting way. I think in this section I'm going to use the cello for more of an atmospheric sort of element, perhaps using some extended techniques. We'll see what happens!
