I interpreted Serial Composition as 7 lines of 6 bars. Each bar has three notes: three horizontal lines with the first on the bottom. Each note can be split in three, so vertical lines are in fact triplets.
The color is the velocity empty/black/red -> 75/100/127.

The composition has 5 voices from the Epic Solo Taiko. Each voice performs each line from top to bottom but loops on each line for a random number of iterations (thanks to Live follow up actions).  I got the idea from In C, and was happy enough with the results here. I keep all voices synchronized on 6 bars, but they do not start all at the same time. The composition stops when all voices have reached the final line.
