An explanation of movements
The piece opens with a single Eb in the tuba. The entire movement has a single goal which is to build an ascending Fibonacci chord (IC +[1,1,2,3,5,8]) This is, as the title of the movement suggests, the birth of the process. This single iteration is drawn out over the course of a minute and a half with is starkly juxtaposed with the material in the next movement.
This movement stems from the Ab which the trumpets end the first movement on. It is comprised of four strands which simultaneously occur. The intervals used in these strands are also derived from a Fibonacci sequence, but the intervals may go in any direction from one note to the next. Each instrumental group (Trumpets, Horns, Trombones, and Euphoneums and Tuba) are each assigned an individual process. The goal of the movement is the convergence on a middle C which leads the Consumption.
Consumption is made from every strand of every possible process. The Fibonacci intervals expand in bother directions from every note from the past step in the process. The ensemble works as an individual unit which grows from an increasing number of points while expanding and converging.
This movement is made up of only descending Fibonacci chords which invoke a bluesy lament. The movement is comprised of a lament melody which is blurred and cascaded down the register until it finally lands of the Eb on which the process for the piece began.
