Event Horizon





Event Horizon was written on a commission from the Volusia (located in the east-central part of Florida) All-County Honor Band, Dr. Gary Green – Conductor, by John Dupius (see below) in 2023.


From the composer:


“I was inspired to write this piece after I learned of the power and mystery of a Black Hole’s event horizon, a point that marks the boundary between a Black Hole and the rest of the universe.





Nothing inside the event horizon can ever escape—the gravity being so strong that not even light can make its way out. The piece begins with an ominous fanfare at a fast pace (152 beats per minute). The phrase following the introduction presents the first appearance of the A theme, followed by a developmental section and transition into the B theme. The C theme serves as a chorale-like movement of peace in an otherwise energetic, pounding and forward-moving work. The piece continues in a return of modified B theme material, a final statement of the A theme, and ends boldly with the initial rhythmic motif introduced first in the ninth measure.”





Composer John Dupuis (b. 1980) received his Bachelor’s degrees in Music Education and Music Composition and his Master of Music degree in conducting, music education and music composition from the University of South Florida.
