The nitrogen cycle is, as the name suggests, a biogeochemical process in which nitrogen takes on many different chemical forms. The main steps of the nitrogen cycle include nitrogen fixation, ammonification, nitrification, and denitrification—all of which are musically analogized in this piece as it relates to the linear process.

The relative toxicity of these chemical compounds—ammonia, nitrite, and nitrate—correspond to dynamics. At an early moment in the piece, ammonia—the most toxic compound—is introduced to the aquarium. As it is the most toxic out of the three, it has the loudest dynamics. Conversely, nitrate is the least toxic with the softest dynamics. It is through the use of these dynamics and an additive tetrachord pitch system, as they relate to continuously shifting levels of chemicals, that Especially in the Context of Aquariums depicts the nitrogen cycle. More specifically, it sonically represents the data of the cycling process collected from my new aquarium in Spring 2021.
