Program Notes:

The title, orbital eccentricity, is a term in astrophysics that determines how far the orbit of a celestial body around another body deviates from a perfect circle. In this work, the traditional ensemble is divided into two opposing groups: a quartet and an octet. These two forces develop their own distinct material, and as the work progresses, these ideas eventually meld together and are then swapped between the two groups.



Commissioned by Zach Shemon and the University of Missouri-Kansas City Saxophone Ensemble.
