Quadrabonix was composed for the Elysian Trombone Consort in the spring of 2015. The eight-minute work is scored for a trombone quartet of three tenor trombones and one bass trombone.  

As the musical ideas of Quadrabonix are introduced, they are recycled and added to subsequent ideas to create a confluence of interrelationships. The concept of a composition as a sonic "time hole" has always fascinated me. Simply put, musical ideas that appear near one another form a relationship; they are colored and influenced by one another. "Time holes" are not purely linear, but that is the traditional way of experiencing them, or that is how we generally believe that we are experiencing them. In music, as in the new physics, time is not only linear – it is multidirectional. Of course, this has always been true, but it has not always been acknowledged or accepted.

Quadrabonix appears in roughly three parts. The outer sections are generally more active, while the inner section takes more time to unfold.
