About the Composer: Erik Morales

Erik Morales was born in New York City in 1966 and began composing during his high school years in South Florida, when his former band director commissioned him to arrange music for the marching band in 1985. He earned his bachelor's degree from the University of Louisiana, Lafayette in 1989, after studying composition at Florida International University. His catalog now includes more than 150 published works spanning wind ensembles, orchestral settings, jazz, and chamber music, with performances featured internationally.
Morales has built a reputation for balancing artistic merit with pedagogical value, a philosophy evident across his educational wind, jazz, and string publications. As a trumpet player himself, he has made significant contributions to the trumpet repertoire; his trumpet ensembles earned first place at the 2006 and 2008 National Trumpet Competitions, and his Concerto for Two Trumpets was premiered at the 2013 International Trumpet Guild conference. He was inducted into the Louisiana Association for Jazz Education's Hall of Fame in 2016 and continues to receive commissions from schools and organizations nationwide.
Why we love this
Morales writes with genuine understanding of what energizes young musicians. The multi-meter structure feels organic rather than forced, giving students genuine rhythmic challenge without overwhelming them at Grade 2.5/3. The relentless percussion battery and layered countermelodies create a soundscape that rivals film scores, which means your ensemble will feel like they're performing something genuinely substantial even as the technical demands stay accessible.
What to expect
Imagine orchestral grandeur filtered through a contemporary sensibility. Vast, resonant sonorities open the work before a driving pulse emerges, propelled by the relentless percussion writing. The music alternates between moments of cosmic stillness and propulsive energy, creating a narrative arc that keeps both players and audiences engaged from start to finish.
Who it's for
Conductors leading Grade 2.5 and 3 concert bands who want their students to experience an accessible but sophisticated work with real theatrical sweep. This piece works for groups seeking meaningful festival or contest repertoire that doesn't require advanced technical chops but demands focused musicianship.
How to get the most out of it
- Establish the ostinato pattern early in rehearsals; once the percussion section locks it in, the entire ensemble finds its rhythmic anchor and can focus on the layered melodies above it.
- Balance the celestial passages by resisting the urge to rush. These moments need space to breathe before the power returns.
- Bring out the countermelodies in the upper woodwinds and brass separately during sectionals so they're audible in the full ensemble mix.
- Use dynamics to shape the journey between sections; the contrast between ethereal and epic is what makes this piece memorable.
How to use it
Program this as a centerpiece work on a festival or contest program where you want to demonstrate your ensemble's range and maturity. It pairs well with more introspective selections earlier in the concert, allowing the work's epic trajectory to provide the climax your audience will remember.
