Cynthia Reynolds was described as "irresistible" by New York Magazine. Her operatic appearances have included a revival of The Accomplish'd Maid (one of the golden hits of 1762!) and a series of rarities presented by the Vineyard Opera.

The Long Island Philharmonic presented her in a touring production of The Magic Flute. Her concert repertory includes such works as The Creation, Messiah (with the Long Island Choral Society and the Waukegan Symphony Orchestra), and both the Poulenc and Vivaldi Gloria. Her theme recital My White Knight, a Hope Chest of Romantic Ballads, has been presented by Arts at St. Paul's in South Nyack and the Donnell Public Library in New York City.  She has participated in a resuscitation of Liza Lehmann's once-famous In a Persian Garden, before a rapt audience at the Liederkranz Club (sound clip below), where she has also been heard in recitals of unusual repertoire on the Elizabeth Hastings Friday Night series.

Her New York career has called her again and again to the G&S repertory; she has starred in The Mikado, Utopia Limited, The Pirates of Penzance and The Gondoliers with New York Gilbert & Sullivan Players, and toured as a member of their select vocal trio. In special concert presentations at The New York Gilbert & Sullivan Society she has added leading roles in The Sorcerer, The Yeomen of the Guard, Ruddigore, Patience, Princess Ida and soon Iolanthe to her "little list." Together with her husband, tenor Richard Slade, she has presented as series of duet concerts featuring romantic scenes from the Gilbert & Sullivan operettas, as well as a concert version of Gounod's Roméo et Juliette.

Miss Reynolds sings regularly in concerts at the First Unitarian Society of Westchester in Hastings on Hudson and has sung victoriana at midnight at the Bowerie Lane Theatre on the Bowery in NYC.

She made her debut with the Asbury Summer Theater in Tuckahoe, NY as the role of Marie in Frank Loesser's operatic music theatre work The Most Happy Fella, has been the soprano soloist on numerous concerts with Sound Shore Chorale in New Rochelle and sang both operatic and art song solos and duets of Arthur Goring Thomas at Symphony Space in New York City (sound clips below).

Miss Reynolds appears frequently as the soprano soloist with the Sound Shore Chorale, most recently as Dido in Purcell's Dido and Aeneas.
