Praised for her “enchanting, glowing timbre and perfect intonation, with a good helping of theatrical spirit” (Weiler Zeitung), British-American soprano Agnes Coakley Cox is specialist in the performance of early Baroque music and a sought-after ensemble musician.


Agnes' desire to bring early music to life has led her to become an expert in the historical performance practice of singing, and she actively applies historical gesture, pronunciation, and ornamentation to her performances. Agnes’ singing is characterized by a genuinely expressive style, a deep level of engagement with the text, and a passion for connecting with the audience. She enjoys collaborating with early music ensembles such as Seven Times Salt, La Fiocco, Long and Away, Les Canards Chantants, MIRYAM, and Les Enfants d’Orphée.


Known for her clear, bright tone and high-caliber musicianship, Agnes is also in demand as a choral musician. She appears regularly with Washington D.C.-based choir The Thirteen, soloing on their 2019 recording Truth & Fable, and has sung with the Washington Bach Ensemble, the Choir of the Church of the Advent, the Schola Cantorum of Boston, Cappella Clausura, and the Boston Camerata.


After graduating summa cum laude in Music at Yale, Agnes studied voice, historical performance practice, and pedagogy at the Schola Cantorum Basiliensis in Basel, Switzerland, where her teacher and mentor was Evelyn Tubb. Agnes lives in Medford, MA with her husband Nathaniel and son Simon. When she is not singing, she can be found knitting, baking, or spotting turtles along the Mystic River.
