Stephen Mager, Composer in Residence


Stephen Mager was appointed composer-in-residence for the Bach Society of Saint Louis in 2004. He has written extensively for chorus and orchestra, and his works have been performed by such distinguished ensembles as the Cleveland Orchestra and Chorus; the Indianapolis Symphony Orchestra Chorus; VocalEssence, Minneapolis; and the Dallas Symphony Chorus.

His choral symphony, Sinfonia Pastorale, received its Saint Louis premiere in 1997 with the Bach Society, to critical praise. The Bach Society has commissioned many of his major choral works: an Easter choral cycle, The Lamb’s High Feast (2005); I saw eternity (2006); in 2008, Missa lucis (“Mass of Light”), aptly described as “lushly lyrical” (Saint Louis Post-Dispatch); an extended, dynamic setting of the Te Deum (2012); and in 2014, Hommage à Saint-Michel, lauded by the Post Dispatch as “a highlight of the program…filled with lovely melodies and interesting effects.” In 2016, his Sarabande (“Arise, shine, for thy light has come”) was composed and premiered to commemorate the 75th anniversary of the Bach Society.

His opera, Dream of the Pacific, was commissioned by Opera Theatre of Saint Louis for the bicentennial of the Lewis and Clark expedition (2004), and subsequently produced by Opera Omaha (2005), Kansas City Lyric Opera (2005), and Washington National Opera (2006), the latter by the young artists program sponsored by Plácido Domingo. “Mager excels at conveying a wide variety of feelings…all in a musical language that is both lyrical and comprehensible” (Washington Post).

His carol settings have also received critical attention and are featured on two compact discs, Joy for Every Age (1998); and more recently, Let Our Gladness Have No End, (2016). “These excellent carol settings . . . exhibit a slightly different kind of charm and sophistication that owes much to their more expansive…fully integrated orchestrations” (David Vernier, His carols are featured on a dozen or more commercial recordings by choral ensembles in the United States. Dr. Mager’s music is published by Oxford University Press and MorningStar Music.

An active choral and opera conductor, he holds a Doctor of Music degree from the Jacobs School of Music, Indiana University, where he also completed his master’s studies. His teachers have included Jan Harrington, Julius Herford, Thomas Binkley, Robert Shaw, Margaret Hillis, Robert Porco, Dale Warland, John Poole, and Carmen-Helena Tellèz. Dr. Mager has served as Artistic Director and Conductor of the Masterworks Chorale, Belleville, Illinois, since 2009. The ensemble performs in an annual subscription concert series, serving the southwest Illinois region.
