David Heuser began composing almost immediately after his first piano lessons at the age of seven, writing short tunes in imitation of the exercises he was studying. He continued to write music throughout his childhood, some for piano, chorus, and wind ensemble, and some for the rock bands he was in. After high school, he attended the Eastman School of Music and then the Indiana University School of Music, where he received his doctorate degree in music composition in 1995. A native of New Jersey, Heuser has resided in San Antonio since 1997. He is an Associate Professor at the University of Texas at San Antonio teaching music composition and theory, and electronic music.

Heuser is a storyteller, crafting emotional journeys for listeners, but his stories go beyond words to things only music can speak to. His over 70 compositions range from exuberant orchestral works to intimate chamber pieces. His most characteristic works are rhythmically active, strongly melodic, and often deal with extremes of tempo, dynamics and register. Just as a painter fills space, a composer fills time, and it is Heuser’s goal to lead the listener through the time his music occupies in a way that is compelling and moving.

Heuser's music has been performed by various groups and individuals and on festivals and conferences throughout the United States and abroad. He has received commissions from such ensembles as the San Antonio Symphony, the New York Youth Symphony, the SOLI Chamber Ensemble, and the Texas Music Festival Orchestra. Heuser has won the 2007 Columbia Orchestra American Composer Competition, the 2006 Fauxharmonic Orchestra Composition Contest, and, most recently, was awarded a grant from the Artist Foundation of San Antonio. He is currently writing his second piece on commission from the Texas Music Festival Orchestra, to be premiered in June, 2008.
