Spencer Simpson
Tenor Spencer Simpson, tenor, is originally from Frederick, Maryland, and spent ten formative years singing in the Frederick Children’s Chorus, from third grade through high school. He continued his musical education at the University of Delaware School of Music, earning a Bachelor of Music in Applied Music – Voice, studying with Blake Smith. Spencer went on to earn a Master’s Degree and a Graduate Artist Certificate in Voice Performance at the University of North Texas College of Music, studying with Molly Fillmore and Mark Tempesta. Spencer’s performance career has encompassed a wide range of genres and styles, including opera, art song, choral music, early music, oratorio, and concert repertoire. His work has taken him to England, Scotland, the Czech Republic, Croatia, and France. Most recently, he appeared as the tenor soloist in the UNT Symphony Orchestra’s performance of Honegger’s King David and performed the role of Ferrando in UNT Opera’s production of Mozart’s Così fan tutte. He has sung with ensembles such as Verdigris Ensemble and Orpheus Chamber Singers, and has taught private voice lessons for three years. Today, while maintaining an active performance career, Spencer serves as the Music Admissions Administrator in the Shepherd School of Music at Rice University. Spencer is fortunate to have had many incredible mentors throughout his life, but he owes a great deal of his success to his time in the Frederick Children’s Chorus. The “Holy Trinity” that is Judy DuBose, Lee DuBose Fuhr, and Ann DuBose, shaped him into not only the musician but also the person he is today. Through their guidance, he not only learned to sing and read music, but also learned patience, empathy, understanding, collaboration, and, above all, that early is on-time, and on-time is late. These remarkable women embodied the spark that ignited Spencer’s lifelong passion for music and created a community where children felt safe to grow, be themselves, learn from mistakes, celebrate joy, and find comfort in times of sadness. Performing tonight as the tenor soloist fulfills a dream Spencer developed thirteen years ago when his voice had (finally) changed and he got to join the Chamber Singers in his very first FCC Messiah. He thanks his parents and grandparents for their steadfast support—especially his grandmother, Nyna, who made every Tuesday night rehearsal special with dinner and a DuBose-Approved Arrival Time™—his brothers, who tolerated his constant singing around the house, and his family, friends, and mentors who have guided him along the way.
