A native of Portland, Oregon, Alexander Kienle has performed as Assistant Principal/Utility horn at the Dallas Symphony Orchestra since 2014. Kienle’s musical adventure started at age five, banging toy bells at a Montessori school, and he began studying piano at six. When his school band already had enough trumpet players, Kienle began studying the horn at 11.

Kienle attended the Juilliard School in New York from 2004 to 2010, where he studied under Jerome Ashby and Julie Landsman. He graduated with a master’s of music in 2010, receiving Juilliard’s William Schumann Award for Outstanding Graduate Student. He has performed with ensembles around the world, including the Los Angeles Philharmonic, the Australian Chamber Orchestra, the St. Paul Chamber Orchestra, the Cincinnati Symphony Orchestra, the Florida Orchestra, and the Verbier Festival Orchestra. He has appeared as a soloist with the Dallas Symphony, the New World Symphony, and the Aspen Conducting Academy Orchestra. Since 2015, Kienle has performed each summer with Music in the Mountains festival orchestra in Durango, and since 2021 has taught at the Aspen Music Festival and School.
