About Cynthia

Described by The Observer [July 2018] as the “unchallenged sovereign of the Ondes Martenot”, Cynthia Millar is in demand with top orchestras around the world. The 2024/25 season will see Cynthia perform Messiaen’s large-scale Turangalîla Symphonie with the BBC Philharmonic at the BBC Proms and Finnish Radio Symphony Orchestra.

Recent seasons have seen Cynthia perform with the Berlin Philharmonic, Orchestre National de France, Brussels Philharmonic, Staatskapelle Dresden, New York Philharmonic, São Paulo Symphony, and the London Symphony Orchestra in London and at the Edinburgh International Festival, working with Sir Simon Rattle, Jaap van Zweden, Kazushi Ono, Simone Young, Cristian Măcelaru and Nicholas Collon. In 2022/23 Cynthia also returned to the LA Philharmonic and San Francisco Symphony to perform Messiaen’s Trois petites liturgies de la présence divine under the baton of Michael Tilson Thomas.

In 2016 Cynthia premiered the Ondes Martenot part specially written for her by Thomas Adès in his opera The Exterminating Angel at the Salzburg Festival, and subsequently at the Royal Opera House, Covent Garden, The Metropolitan Opera and the Royal Danish Opera in March 2018. The 2016-17 season also saw her take part in a ten-concert tour of the Turangalîla Symphonie with the Simon Bolivar Symphony Orchestra and Gustavo Dudamel, beginning in Caracas and culminating in a sold-out concert at Carnegie Hall, New York.

Cynthia has recorded Turangalîla with the Bergen Symphony Orchestra for Juanjo Mena; and the Trois petites liturgies with the Seattle Symphony for Ludovic Morlot and the London Sinfonietta for Terry Edwards. She has played in well over 100 film and television scores and has written music for film, television and theatre, including scores for Robert Wise, Arthur Penn, Martha Coolidge and Peter Yates.

  • Turangalîla-Symphonie

    London Symphony Orchestra
    Jun 2023
    • ★★★★★ [Rattle] was joined by the pianist Peter Donohoe and the ondes Martenot specialist Cynthia Millar, both of whom are steeped in the unique and unbridled sound world of this inimitable score. The rapport between them, allied to Rattle’s control of the work’s many loud but also its quieter sections – the latter contain some of Messiaen’s best writing – were all of the highest order.

    • ★★★★★ Millar brought consummate expertise and humour to her part.
