“Metabolism is the set of life-sustaining chemical transformations within the cells of living organisms. The word Metabolism also can refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells.” - Wikipedia
In this piece, I wanted to focus on blood cells and their voyage from one vessel to another. The blood cells transport a variety of materials including oxygen, nutrients, waste, and signals to organs and tissues throughout our body. These substances are expressed in the music as different stratifications of foreground and background, as well as sparkling gestures. Vessel diameter and length vary enormously and they influence the resistance to blood flow within a single vessel. The changes of density in the music depict the blood flow as blood cells travel from place to place. As blood cells move towards the heart, the pulsation in the piece becomes more prominent.
