Mark Miller | Decani Tenor

Tony Domenick | Decani Bass

Tony is a performer, teacher, conductor, and composer from Denver, Colorado. His primary instrument was alto saxophone until his high school band director convinced him to try trombone, his Presbyterian choir director convinced him to sing, and a close friend taught him to play “Take 5” and “Für Elise” on the piano. Tony also plays ukulele, and loves the different ideas each of these instruments can inspire. He performs with choirs, rock bands, improv troupes, at weddings and funerals; teaches private voice, piano, song writing, and music theory lessons; conducts choirs and orchestras; and composes choral music, songs of all genres, and chamber music. Tony embraces music as a language, and he loves to help others become fluent. When he's not making music, he is making spicy burritos, reading philosophy, hiking with his partner Kelsie, over-analyzing the economic implications of board games, and meditating.
