Academic Dean, Young Musicians Program

At the encouragement of her mother, Cara Haxo begrudgingly attended Walden as a student in 2004.

I am an oboist, singer, educator and composer, and do my best to avoid being boxed into any of these categories. I am currently completing a master’s degree in baroque oboe at the Juilliard School, and have performed with the Juilliard415 orchestra in Lincoln Center, Paris, New Zealand and San Francisco. I sing in the professional choir at St. James Episcopal Church in Manhattan as a mezzo-soprano. I am a music theory teaching assistant for Juilliard’s Evening Division, and previously served as oboe fellow for Juilliard’s Music Advancement Program (MAP) where I had the opportunity to design and teach advanced music seminars.

Before moving to New York I enjoyed life as a freelance musician in Seattle, singing at St. James Cathedral, teaching piano and composition at Puget Sounds Piano Academy, and teaching oboe for the Seattle Youth Symphony. I founded Les Chanterelles, a professional a cappella ensemble specializing in medieval and contemporary music, and performed in concerts presented by Early Music Seattle, Music at 9th and Stewart, and Tacoma Early Music. I gave numerous solo recitals, premiering my own compositions and other new works alongside classic repertoire.

Some of my favorite musical moments have been experimental, genre-bending collaborations: playing in a funk orchestra with jazz bassist Evan Flory-Barnes for his show “On Loving the Muse and Family,” playing with the Seattle Rock Orchestra, and collaborating with Jason Everett’s Deep Energy Orchestra in a fusion between Indian classical and prog rock. I have worked with people of various spiritual traditions, including as a soloist with the Medieval Women’s Choir, a season with the Seattle Jewish Choir, gospel music with St. Paul’s UMC in Brooklyn, new music composed for a Hare Krishna service, and monthly improvisations for Taizé (Christian mysticism).

I hold a MA in solo voice ensemble singing from the University of York (UK) and double bachelor’s degrees in neuroscience and oboe performance from Oberlin College and Conservatory. In my spare time I enjoy creative coding, 3D printing, vegetarian cooking and urban cycling.
