OK, here’s another technique I tried out yesterday when composing possible tracks with Ableton Live. I had a section where I wanted pad-like melodies, but not the same one to avoid sounding boring.
So instead I took four different pad loops, and had each one playing just one bar, but all together it was four bars. This way it sounded really intriguing, like four different sections each playing their own part.
I think in orchestral music this is also used to emphasize parts, let’s say violins play a part, then the horns. But with loops and editing it’s really easy to do something similar.
