"lo" is the introductory movement of a four-part suite, entitled Four Moons for Brass Quartet. As suggested by the title, the four movements of the work were modeled after a specific set of astronomical entities, the four Galilean moons of Jupiter. These celestial satellites provided inspiration for this work in a number of different ways. Scientific observations and measurements for each moon, such as diameter, mass, density and composition, provided melodic and harmonic ideas through a 20th century musical process that is commonly referred to as "pitch set theory." The visual and physical qualities of each moon, and their relationships with one another, also influenced many musical decisions. The programmatic directions of the various movements were derived, in part, from the Greek mythology associated with the names of each moon: 10, Europa, Ganymede and Callisto.
