Washington based mezzo-soprano, Rosamund Dyer has been described as a “powerhouse” possessing “beauty and depth”. As a 2025 Studio Artist with the Chautauqua Opera Company, Rosamund was seen as Mrs. McNeil (Ida by Lamplight), and as Mrs. Baron alongside soprano Christine Georke in composer Missy Mazzoli and librettist Royce Vavrek’s newest commission from the The Metropolitan Opera, Lincoln in the Bardo. She was the Studio Artist at Pacific Northwest Opera for their 2024-2025 season, covering Dame Quickly (Falstaff), Ježibaba (Rusalka), and the Foreign Princess (Rusalka). A passionate Teaching Artist, she has worked with Seattle Opera as Ruth (The Pirates of Penzance), and spent two springs with the Chautauqua Opera Company in Joshua Borths’s operatic adaptations - the Third Little Pig (Who’s Afraid of the Big, Bad Wolf?), and Aunt Bartolo (The Barber of Seville in California).


As a concert soloist, Rosamund was the Alto soloist in Gustav Mahler’s Symphony No. 2 with the Chautauqua Symphony Orchestra and the Buffalo Philharmonic Chorus, the Alto soloist in Handel’s Messiah with the Columbus Symphony and Columbus Symphony Chorus, and a featured soloist in Music of Remembrance’s program “Echos of Conscience”, performing songs from the French resistance written in reaction to WWII. Rosamund has joined the Bellingham Chamber Chorale’s performances of Handel’s Messiah as the Alto Soloist, and sung all of the baritone solos in their recently reimagined Fauré’s Requiem.

Most recent operatic appearances include the Marquise of Berkenfield (La fille du régiment), Eustazio (Rinaldo), Dorabella (Così fan tutte), Alise (Lucia di Lammermoor), and Hera (La Callas). She was awarded third place (2024) and second place (2025) in the Seattle Opera Guild’s Annual Singers’ Development Competition.

This coming season, Rosamund is excited to have four role debuts - Prince Orlofsky (Die Fledermaus), Fenena (Nabucco), The Third Lady (The Magic Flute), and her Vashon Opera debut as Elizabeth Proctor (The Crucible).

Rosamund has a Bachelor of Music in Vocal Performance from the Oberlin Conservatory of Music, graduating in 2020 with highest honors as a National Music Honor Society Pi Kappa Lambda Scholar. Rosamund has studied with Marilyn Horne, Timothy LeFebvre and is currently studying with Metropolitan Opera Baritone, Erich Parce.

Beyond the stage, Rosamund has worked in Arts Administration at Carnegie Hall, the American Opera Projects, Heartbeat Opera and the Beth Morrison Projects to nurture emerging composers and librettists in the creation of meaningful contemporary opera.
