Dylan Madoux

Dylan earned his graduate degree (MM) at Oklahoma City University where he studied Harpsichord Performance with Professor Anastasia Abu Bakar and Professor Joseph Ripka as well as having completed his Orchestral Conducting degree with Professor Jeffrey Grogan.

Dylan has had success as a conductor and is known for his unique “vignette-style” programming where he is able to masterfully capture the essence of a given time and place. He currently serves as Artistic Director of the Oklahoma Baroque Orchestra and Music Director of the Vitam Musica Foundation. After founding Vitam Musica and the Vitam Musica Chamber Orchestra, Dylan has collaborated with numerous musicians and artists across Oklahoma. In partial collaboration with the University of Oklahoma School of Dance, Dylan premiered the original ballet, “Bloch to Bach—A Tour de Force”, at Vitam Musica’s debut performance in Spring 2019. Since then, he has led the Vitam Musica Chamber Orchestra and Oklahoma Baroque Orchestra in numerous concerts featuring a wide range of soloists and repertoire. 

From fall 2020-spring 2022, Dylan served as an Apprentice Conductor at the Oklahoma City Philharmonic and an Assistant Conductor at Oklahoma Youth Orchestras. In the summer of 2021 and 2022, Dylan had the opportunity to conduct and work with the Boise Baroque Orchestra and Maestro Robert Franz during their workshop and festival and has performed as guest principal harpsichordist since during their normal concert.

Dylan has played continuo in Oklahoma City University’s Early Music Ensemble, the Boise Baroque Orchestra, University of Oklahoma Collegium Musicum, Tactus Chamber & Vocal Ensemble, and various other recital and concert settings. While Dylan does not consider himself an organist, he has found joy in instrument repairs and in his work as a Pipe Organ Technician at the Red River Pipe Organ Co..
