Lauded for her "spectacular tone" and "impressive extension", Boston-based coloratura soprano Caroline Spaeth is becoming known for her ease with exciting vocal pyrotechnics. She has been particularly regarded for her "dead-center accuracy" in fast passagework and “fantastic” notes above the staff. She spent July 2019 performing with the prestigious Trentino Music Festival in Fiera di Primiero, where she sang Najade and covered Zerbinetta in Ariadne auf Naxos. August 2019 marked her debut with the Cambridge Community Chorus, with whom she performed the soprano solos in Carmina Burana. A regional winner in the 2019 CS Music Competition, she also debuted with the Contemporary Theater Company in Wakefield, RI as Lucy in Menotti’s The Telephone in February 2019. She later reprised the role in the famed Arctic Playhouse in Warwick, RI.

In August 2018, Caroline sang the notorious Queen of the Night in Mozart's  Die Zauberflöte with Seattle's German Vocal Arts Institute. She also appeared as the soprano soloist in Masterworks Chorale’s Messiah Sing, a celebrated tradition in the Boston area. Caroline’s 2016-2017 season included her European debut with the Assisi Performing Arts Festival in Italy, where she sang Gilda in Rigoletto. In Boston, she was heard as a soprano soloist with Calliope Music in Mozart's Davidde Penitente and Dvorak's St. Ludmila. 2017 also featured debuts with Cambridge Chamber Ensemble, where she sang the roles of Miss Silverpeal (The Impresario) and Clarice (A Game of Whist) in a set of sold-out performances. Later that season, she was seen as the tempestuous Lilli Vanessi/Katherine, considered one of musical theatre’s finest soprano roles, in the MIT Gilbert and Sullivan Society's production of the Cole Porter classic Kiss Me, Kate. She received a 2018 BroadwayWorld Regional Theatre Award nomination as Best Actress in a Musical for her performance. Caroline’s other roles in preparation include Olympia (Les contes d’Hoffmann), Marie (La Fille du Regiment), and Tytania (A Midsummer Night’s Dream).

A frequent interpreter of Mozart, Caroline's other solo engagements include the Requiem with Masterworks Chorale and the Mass in C minor with Calliope Music. In 2015, she was selected as a Vocal Apprentice with the Vermont Music and Arts Center. Subsequently, she appeared as a soprano soloist in works such as Bach's Magnificat and Schubert's Erstes Offertorium with the Festival. She also sang notable works for soprano and chamber ensemble such as Die Hirt auf dem Felsen.

Caroline is also no stranger to the recital stage. She regularly appears around the Boston area with award-winning pianist Caroline Ly, with programs ranging from lieder to Broadway showtunes. Her warm stage presence and theatrical interpretations have made her a favorite with older and younger audiences alike. A roster artist with Longwood Opera, she has performed to much audience acclaim during their annual summer concert series.

Besides performing, Caroline has a special passion for teaching and sharing the joy of singing with students. She teaches singers and beginning to intermediate pianists of all ages privately in the Metro Boston area, and serves on the faculty of MJ's Music School in Waltham and Amy Dancz Studio in Downtown Boston.
